SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

      Statements in this prospectus supplement, the accompanying prospectus and the incorporated documents that are not historical facts are hereby identified as “forward-looking statements” for the purpose of the safe harbor provided by Section 21E of the Securities Exchange Act of 1934 and Section 27A of the Securities Act of 1933. Although we believe that our expectations are based on reasonable assumptions within the bounds of our knowledge of our business and operations, there can be no assurance that actual results will not differ materially from our expectations. Factors that could cause actual results to differ from expectations include:

      Readers are cautioned that other factors discussed in the documents incorporated by reference in this prospectus supplement and accompanying prospectus, although not enumerated here, also could materially impact our future earnings.

      You should not construe these cautionary statements as an exhaustive list or as any admission by us regarding the adequacy of our disclosures. We cannot always predict or determine after the fact what factors would cause actual results to differ materially from those indicated by our forward-looking statements or other statements. In addition, you are urged to consider statements that include the terms “believes,” “belief,” “expects,” “plans,” “objectives,” “anticipates,” “intends” or the like to be uncertain and forward-looking. All cautionary statements should be read as being applicable to all forward-looking statements wherever they appear.

      We do not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed herein might not occur.

USE OF PROCEEDS

      The net proceeds from the sale of the SBC common stock will be approximately $233,560,000, after deducting underwriting discounts and commissions and estimated offering expenses. These proceeds will be used for general corporate purposes.

PENDING ACQUISITION OF AT&T

      On January 30, 2005, we agreed to acquire AT&T Corp., or AT&T, using shares of SBC common stock. Based on the closing price of SBC common stock on January 28, 2005, the total transaction is valued at approximately $16 billion, including a special dividend to be paid to AT&T shareholders at the closing. The transaction has been approved by the board of directors of each company and also must be approved by the shareholders of AT&T. The transaction is subject to review by the Department of Justice and approval by the Federal Communications Commission and various other regulatory authorities. Information about the merger and AT&T is

contained in the documents listed in the section of the accompanying prospectus entitled “Documents Incorporated by Reference”.

PER SHARE MARKET PRICE DATA AND DIVIDEND INFORMATION

      The table below sets forth, for the calendar quarters indicated, the high and low sales prices per share reported on the NYSE composite transactions reporting system and the dividends declared on SBC common stock.

      On May 31, 2005, the last sale price per share of SBC common stock was $23.38 on the NYSE composite transactions reporting system.

UNDERWRITING

      SBC, its subsidiary, SBC Hedging Management L.L.C., and Deutsche Bank Securities Inc. have entered into an underwriting agreement with respect to the shares offered hereby. Subject to certain conditions, the underwriter has agreed to purchase the 10,000,000 shares.

      The underwriter is committed to take and pay for all of the shares being offered, if any are taken.

      Shares sold by the underwriter to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. If all the shares are not sold at the initial public offering price, the underwriter may change the offering price and the other selling terms.

      In connection with the offering, the underwriter may purchase and sell shares in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriter of a greater number of shares than it is required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the SBC common stock while the offering is in progress.

      The underwriter also may impose a penalty bid. This occurs when a particular dealer repays to the underwriter a portion of the underwriting discount received by it because the underwriter

has repurchased shares sold by or for the account of such dealer in stabilizing or short covering transactions.

      These activities by the underwriter may stabilize, maintain or otherwise affect the market price of the SBC common stock. As a result, the price of the SBC common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriter at any time. These transactions may be effected on the New York Stock Exchange, the Chicago Stock Exchange, the Pacific Stock Exchange, in the over-the-counter market or otherwise.

      We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $90,000.

      We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933.

      The underwriter and its affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses.

VALIDITY OF COMMON STOCK

      James D. Ellis, Senior Executive Vice President and General Counsel of SBC, is passing upon the validity of the shares of SBC common stock for us.

Summary Description of the Securities We May Issue

      We may use this prospectus to offer up to U.S. $10,500,000,000 (or the equivalent) of:

      In the case of securities that are exchangeable for securities of a third party issuer, the applicable prospectus supplement will give you more information about this issuer, the terms of its securities and the document in which they are described. Our securities include securities denominated in U.S. dollars, but we can choose to issue securities in any other currency, including the Euro.

      A prospectus supplement will describe the specific types, amounts, prices and detailed terms of any of these securities.

Description of Debt Securities We May Offer

      As required by U.S. federal law for all bonds and notes of companies that are publicly offered, our debt securities will be governed by a document called the indenture. The indenture is a contract between us and The Bank of New York, which acts as trustee for you. The trustee has two main roles:

      We may issue as many distinct series of securities under the indenture as we wish. This section summarizes terms of the securities that are common to all series. Most of the financial terms and other specific terms of your series are described in the prospectus supplement attached to the front of this prospectus. Those terms may vary from the terms described here. The prospectus supplement may also describe special federal income tax consequences of the debt securities.

This Section Is Only a Summary

      This section and your prospectus supplement summarize all the material terms of the indenture and your debt securities. They do not, however, describe every aspect of the indenture and your debt securities.

      The indenture and its associated documents, including your debt securities, contain the full text of the matters described in this section and your prospectus supplement. The indenture and the debt securities are governed by New York law. A copy of the indenture has been filed with the Securities and Exchange Commission, or SEC, as part of our registration statement. See “Where You Can Find More Information” below for information on how to obtain a copy. Section references in the description that follows relate to the indenture.

Legal Ownership of Debt Securities

      We can issue debt securities in registered or bearer form or both, or in the form of one or more global securities. We refer to those who have debt securities registered in their own names on the books that we or the trustee maintain for this purpose, or who hold bearer certificates representing bearer debt securities, as the “holders” of those debt securities. These persons are the legal holders of the debt securities. We refer to those who, indirectly through others, own beneficial interests in debt securities that are not registered in their own names as “indirect holders” of those debt securities. As we discuss below, indirect holders are not legal holders, and investors in debt securities issued in book-entry form or in street name will be indirect holders.

      We may issue debt securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means debt securities may be represented by one or more global securities registered in the

name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, in turn, hold beneficial interests in the debt securities on behalf of themselves or their customers.

      For registered debt securities, only the person in whose name a debt security is registered is recognized under the indenture as the holder of that debt security. Debt securities issued in global form will be issued in the form of a global security registered in the name of the depositary or its participants. Consequently, for debt securities issued in global form, we will recognize only the depositary as the holder of the debt securities and we will make all payments on the debt securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the debt securities.

      As a result, investors in a book-entry security will not own debt securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the debt securities are issued in global form, investors will be indirect holders, and not holders, of the debt securities.

      In the future we may terminate a global security or issue debt securities initially in non-global form. In these cases, investors may choose to hold their debt securities in their own names or in “street name”. Debt securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those debt securities through an account he or she maintains at that institution.

      For debt securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the debt securities are registered as the holders of those debt securities and we will make all payments on those debt securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold debt securities in street name will be indirect holders, not holders, of those debt securities.

      Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to the legal holders of the debt securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a debt security or has no choice because we are issuing the debt securities only in global form.

      For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose — e.g., to amend the applicable indenture or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the applicable indenture — we would seek approval only from the holders, and not the indirect holders, of the debt securities. Whether and how the holders contact the indirect holders is up to the holders.

      When we refer to you, we mean those who invest in the debt securities being offered by this prospectus, whether they are the holders or only indirect holders of those debt securities. When we refer to your debt securities, we mean the debt securities in which you hold a direct or indirect interest.

      We will offer debt securities in bearer form only outside of the United States to non-U.S. persons. You generally are a non-U.S. person if you are not:

      In addition, we may offer bearer securities to offices of some U.S. financial institutions who have offices located outside the United States. We will describe any special restrictions on the offer, sale and delivery of bearer debt securities and any special federal income tax considerations applicable to bearer debt securities in the prospectus supplement.

      If you hold debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

What Is a Global Security?

      A global security is a security held by a depositary, which represents one or any other number of individual debt securities. Generally, all debt securities represented by the same global securities will have the same terms.

      Each debt security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all debt securities issued in book-entry form.

      A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under “— Special Situations When a Global Security Will Be Terminated”. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all debt securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial

institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the debt security, but only an indirect holder of a beneficial interest in the global security.

      If the prospectus supplement for a particular debt security indicates that the debt security will be issued in global form only, then the debt security will be represented by a global security at all times unless and until the global security is terminated. We describe the situations in which this can occur below under “— Special Situations When a Global Security Will Be Terminated”. If termination occurs, we may issue the debt securities through another book-entry clearing system or decide that the debt securities may no longer be held through any book-entry clearing system.

      As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize this type of investor as a holder of debt securities and instead deal only with the depositary that holds the global security.

      If debt securities are issued only in the form of a global security, an investor should be aware of the following:

      In a few special situations described below, the global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own bank or brokers to find out how to have their interests in securities transferred to their own name, so that they will be

direct holders. We have described the rights of holders and street name investors above under “— Legal Ownership of Debt Securities”.

      The global security will terminate when the following special situations occur:

      The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the prospectus supplement. When a global security terminates, the depositary — and not we or the trustee — is responsible for deciding the names of the institutions that will be the initial direct holders. (Sections 2.08(f) and (g))

Overview of Remainder of This Section

      The remainder of this section summarizes:

Additional Mechanics

      The securities will be issued:

      You may have your securities broken into more securities of smaller denominations or combined into fewer securities of larger denominations, as long as the total principal amount is not changed. This is called an “exchange”. (Section 2.08(a))

      If you are holding bearer securities and it is permitted by the terms of your series of debt securities, you may exchange bearer debt securities for an equal amount of registered or bearer debt securities of the same series and date of maturity. No bearer debt securities will be exchanged for registered securities if in doing so we would suffer adverse consequences under any U.S. law applicable to the exchange. Registered debt securities may not be exchanged for bearer debt securities.

      You may exchange or transfer your securities at the office of the registrar. The registrar acts as our agent for registering securities in the names of holders and for transferring and exchanging securities, as well as maintaining the list of registered holders. We have appointed The Bank of New York to perform the role of registrar. We may change this appointment to another entity or perform it ourselves. In order to exchange bearer securities, you have to deliver them to the paying agent, together with all unmatured coupons for interest and all matured coupons in default. (Section 2.08(b))

      We can designate additional registrars or paying agents, acceptable to the trustee, and they would be named in the prospectus supplement. We may cancel the designation of any particular registrar or paying agent. We may also approve a change in the office through which any registrar or paying agent acts. We must maintain a registrar and paying agent office in the Borough of Manhattan in New York City. If at any time we do not maintain a registrar or paying agent, the trustee will act as such. (Section 2.04)

      There is no charge for exchanges and transfers. You will not be required to pay a service charge to transfer or exchange securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the registrar is satisfied with your proof of ownership. (Section 2.08)

      At certain times, you may not be able to transfer or exchange your securities. If we redeem any series of securities, or any part of any series, then we may prevent you from transferring or exchanging these securities. We may do this during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders so we can prepare the mailing. We may also refuse to register transfers or exchanges of securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any security being partially redeemed. (Section 2.08(d))

      If you bring a mutilated certificate or coupon to the trustee, we will issue a new certificate or coupon to you in exchange for the mutilated one. Please note that the trustee may have additional requirements that you must meet in order to do this. (Section 2.09)

      If you claim that a certificate or coupon has been lost, completely destroyed, or wrongfully taken from you, then the trustee will give you a replacement certificate or coupon if you meet the trustee’s requirements. Also, we may require you to provide reasonable security or indemnity to protect us from any loss we may incur from replacing your certificates or coupons. We may also charge you for our expenses in replacing your security. (Section 2.09)

      We will pay interest to you if you are a direct holder listed in the registrar’s records at the close of business on a particular day in advance of each due date for interest, even if you no longer own the security on the interest due date. That particular day, usually about two weeks in advance of the interest due date, is called the “record date” and is stated in the prospectus supplement. (Section 2.05) Holders buying and selling securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the one who is the registered holder on the record date. The most common manner is to adjust the sales price of the securities to prorate interest fairly between buyer and seller. This prorated interest amount is called “accrued interest.”

      We will pay interest, principal and any other money due on the securities at the corporate trust office of the trustee in New York City. That office is currently located at The Bank of New York, 101 Barclay Street, Floor 8 West, New York, New York 10286. You must make arrangements to have your payments picked up at or wired from that office. We may also choose to pay interest by mailing checks. (Section 2.05)

      We may also arrange for additional payment offices, and may cancel or change these offices, including our use of the trustee’s corporate trust office. These offices are called “paying agents”. We may also choose to act as our own paying agent. We must notify you if we change the paying agents for any particular series of securities. (Section 2.04)

      We will only pay interest on bearer debt securities when you present and surrender the coupons for the interest installments evidenced by the bearer securities as they mature. You have to present your coupons at a paying agency of SBC located outside of the United States. We will maintain a non-U.S. paying agent for two years after the principal of a series of bearer debt securities has become due. We will continue to maintain the paying agent after that period, if it is necessary to comply with U.S. tax law or regulations. We will provide the paying agent with the necessary funds for payment upon reasonable notice. We generally will not make any payments in the United States. However, if payment outside of the United States is illegal or precluded by exchange controls or similar restrictions in a foreign country, we may instruct the trustee to make payments at a paying agent located in the United States. (Section 2.05(c))

      You can prove your ownership of a bearer security by presenting the actual security, or a certificate or affidavit executed by the person holding the bearer security or executed by a depositary with whom the bearer securities were deposited, if the trustee is satisfied with the certificate or affidavit. (Section 2.07(b))

      We and the trustee will send notices regarding the securities only to direct holders, using their addresses as listed in the trustee’s records. (Section 10.02)

      Regardless of who acts as paying agent, all money we forward to a paying agent that remains unclaimed will, at our request, be repaid to us at the end of two years after the amount was due to the direct holder. After that two-year period, you may look only to us for payment and not to the trustee, any other paying agent or anyone else. (Section 8.03)

Special Situations

      We are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company, or to buy substantially all of the assets of another company. However, we may not take any of these actions unless all the following conditions are met:

      Under certain circumstances, we can make changes to the indenture and the securities. Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all. (Sections 9.01-9.06)

      Changes Requiring Your Approval. First, there are changes that cannot be made to your securities without your specific approval. Following is a list of those types of changes:

      Changes Requiring a Majority Vote. The second type of change to the indenture and the securities is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect holders of the securities. The same vote would be required for us to obtain a waiver of a past default. However, we cannot obtain a waiver of a payment default or any other aspect of the indenture or the securities listed in the first category described previously under “— Changes Requiring Your Approval” unless we obtain your individual consent to the waiver. (Section 9.02(a))

      Changes Not Requiring Your Approval. The third type of change does not require any vote by holders of securities. This type is limited to clarifications of ambiguous contract terms and other changes that would not adversely affect holders of the securities. (Section 9.01)

      Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

      Securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. A security does not cease to be outstanding because we or an affiliate of us is holding the security. (Section 2.10)

      We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding securities that are entitled to vote or take other action under the indenture. However, the indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date. (Section 9.02(b))

Discharge of Our Obligations

      We can fully discharge ourselves from any payment or other obligations on the securities of any series if we make a deposit for you with the trustee. The deposit must be held in trust for your benefit and the benefit of all other direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

      However, we cannot discharge ourselves from the obligations under any convertible or exchangeable securities, unless we provide for it in the terms of these securities and the prospectus supplement.

      If we accomplish full discharge, as described above, you will have to rely solely on the trust deposit for repayment of the securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

      We will indemnify the trustee and you against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the trustee or against the principal and interest received on these obligations. (Sections 8.01-8.04)

Redemption

      We may be able to pay off your securities before their normal maturity. If we have this right with respect to your specific securities, the right will be mentioned in the prospectus supplement. It will also specify when we can exercise this right and how much we will have to pay in order to redeem your securities.

      If we choose to redeem your securities, we will mail written notice to you not less than 30 days prior to redemption, and not more than 60 days prior to redemption. Also, you may be prevented from exchanging or transferring your securities when they are subject to redemption, as described under “— Form, Exchange and Transfer” above. (Article 3)

Liens on Assets

      The indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

Default and Related Matters

      The securities are not secured by any of our property or assets. Accordingly, your ownership of securities means you are one of our unsecured creditors. The securities are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the trustee has a right to receive payment for its administrative services prior to any payment to security holders after a default.

      You will have special rights if an event of default occurs and is not cured, as described later in this subsection.

      What Is an Event of Default? The term “event of default” with respect to any series of securities means any of the following:

      You will have the following remedies if an event of default occurs:

      Acceleration. If an event of default has occurred and has not been cured or waived, then the trustee or the holders of 25% in principal amount of the securities of the affected series may declare the entire principal amount of and any accrued interest on all the securities of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the securities of the affected series, if all events of default have been cured or waived. (Section 6.02)

      Special Duties of Trustee. If an event of default occurs, the trustee will have some special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs. (Section 7.01)

      Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests. The trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an “indemnity”. If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the indenture. (Section 6.05)

      Individual Actions You May Take if the Trustee Fails to Act. Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the securities, the following must occur:

      However, you are entitled at any time to bring an individual lawsuit for the payment of the money due on your security on or after its due date. (Section 6.07)

      The holders of a majority in principal amount of the relevant series of debt securities may waive a default for all the relevant series of debt securities. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on your debt security, however, without your individual approval. (Section 6.04)

      Every year we will give to the trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the indenture and the debt securities, or else specifying any default. (Section 4.03)

      The trustee may withhold from you notice of any uncured default, except for payment defaults, if it determines that withholding notice is in your interest. (Section 7.05)

Original Issue Discount Securities

      The debt securities may be issued as original issue discount securities, which will be offered and sold at a substantial discount from their principal amount. Only a discounted amount will be due and payable when the trustee declares the acceleration of the maturity of these debt securities after an event of default has occurred and continues, as described under “— Remedies if an Event of Default Occurs” above.

Conversion of Convertible Debt Securities

      Your debt securities may be convertible into our preferred stock, including depositary shares representing preferred stock, or common stock, or they may be exchangeable for equity securities of another issuer if the prospectus supplement so provides. If your debt securities are convertible or exchangeable, the prospectus supplement will include provisions as to whether conversion or exchange is mandatory, at your option or at our option. The prospectus supplement would also include provisions regarding the adjustment of the number of shares of common stock or other securities you will receive upon conversion or exchange. In addition, the prospectus supplement will contain the conversion price or exchange price and mechanisms for adjusting this price. In the case of exchangeable debt securities, the prospectus supplement will set forth information about the issuer for whose securities you would exchange your debt, or where that information can be found.

      Unless it is specified in the prospectus supplement, we will not adjust the exchange or conversion price of your debt securities for interest on your securities or for any dividends payable on the new securities you will receive. However, if you convert or exchange your securities between a regular record date for the payment of interest and the next following interest payment date, you must include funds equal to the interest that would be payable on your securities on this following interest payment date. We are not required to issue fractional shares of preferred stock, depositary shares or common stock, but, unless we otherwise specify in the prospectus supplement, we will pay you a cash adjustment calculated on the basis of the following:

      You may be deemed to have received a distribution that would be taxed as a dividend under U.S. federal income tax law in a number of circumstances where you receive a distribution that results in an adjustment of the conversion or exchange price of your securities. In other circumstances, if your conversion or exchange price will not be adjusted, that may result in a taxable dividend on the common stock or preferred stock that you will receive upon conversion or on the securities that were exchanged for debt securities.

      We maintain banking relationships in the ordinary course of business with the trustee. The trustee is also the trustee under indentures with others of our subsidiaries.

Description of Preferred Stock

      The following briefly summarizes the material terms of our preferred stock other than pricing and related terms disclosed in the accompanying prospectus supplement. You should read the particular terms of any series of preferred stock we offer, which will be described in more detail in the prospectus supplement relating to that series. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered. In addition, for each series of preferred stock, we will file a certificate of designations containing the specific terms of the series as an exhibit to the registration statement or we will incorporate it by reference before we issue any preferred stock.

General

      We are authorized to issue up to 10,000,000 shares of preferred stock, par value $1.00 per share. Under our restated certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series. To establish a series of preferred stock our board must set the following terms:

      Before we issue any series of preferred stock, our board of directors will adopt resolutions creating and designating the series as a series of preferred stock. Stockholders will not need to approve these resolutions.

      As of April 21, 2005, no shares of preferred stock were outstanding.

Terms Contained in Prospectus Supplement

      A prospectus supplement will contain the dividend, liquidation, redemption and voting rights of a series of preferred stock. The prospectus supplement will describe the following terms of a series of preferred stock:

No Preemptive Rights

      The holders of preferred stock will have no preemptive rights to buy any additional shares. The preferred stock will be, when issued, fully paid and nonassessable. Neither the par value nor the liquidation preference can show you the price at which the preferred stock will actually trade on or after the date of issuance. The applicable prospectus supplement will describe some of the U.S. federal income tax consequences of the purchase and ownership of the series of preferred stock.

Description of Depositary Shares

      We may offer depositary shares evidenced by depositary receipts. Each depositary receipt represents a fraction of a share of the particular series of preferred stock issued and deposited with a depositary. The fraction of a share of preferred stock which each depositary share represents will be set forth in the prospectus supplement relating to those depositary shares.

      We will describe the transfer agent for each series of preferred stock in the applicable prospectus supplement.

Description of Depositary Shares

      The following briefly summarizes the material provisions of the deposit agreement and of the depositary shares and depositary receipts, other than pricing and related terms disclosed in the accompanying prospectus supplement. You should read the particular terms of any depositary shares and any depositary receipts that we offer. You should also read the deposit agreement relating to the particular series of preferred stock and the more detailed description of the deposit agreement in the prospectus supplement. The prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered.

General

      We will deposit the shares of any series of preferred stock represented by depositary shares according to the provisions of a deposit agreement between us and a bank or trust company which we will select as our preferred stock depositary. The depositary must have its principal office in the United States and have a combined capital and surplus of at least $50,000,000. Each owner of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock in proportion to the applicable fraction of a share of preferred stock represented by the depositary share. These rights include dividend, voting, redemption, conversion and liquidation rights. The depositary will send you all reports and communications which we will deliver to the depositary and which we have to furnish to you.

      The following is a summary of the deposit agreement. For more complete information, you should read the entire agreement and the depositary receipt. Directions on how to obtain copies of these are provided under “Where You Can Find More Information” below.

Depositary Receipts

      The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to anyone who is buying the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement. We will either file the forms of deposit agreement and depositary receipt as exhibits to the registration statement of which this prospectus is a part, or we will incorporate them by reference into that registration statement.

      While definitive engraved depositary receipts (certificates) are being prepared, we may instruct the depositary to issue temporary depositary receipts, which will entitle you to all the rights of the definitive depositary receipts and be substantially in the same form. The depositary will prepare definitive depositary receipts without unreasonable delay, and we will pay for the exchange of your temporary depositary receipts for definitive depositary receipts.

Withdrawal of Preferred Stock

      You may receive the number of whole shares of your series of preferred stock and any money or other property represented by those depositary receipts after surrendering the depositary receipts at the corporate trust office of the depositary. Partial shares of preferred stock will not be issued. If the depositary shares which you surrender exceed the number of depositary shares that represent the number of whole shares of preferred stock you wish to withdraw, then the depositary will deliver to you at the same time a new depositary receipt evidencing the excess number of depositary shares. Once you have withdrawn your preferred stock, you will

not be entitled to re-deposit that preferred stock under the deposit agreement in order to receive depositary shares. We do not expect that there will be any public trading market for withdrawn shares of preferred stock.

Dividends and Other Distributions

      The depositary has agreed to pay to you the cash dividends or other cash distributions it receives on preferred stock, after deducting its fees and expenses. You will receive these distributions in proportion to the number of depositary shares you own. The depositary will distribute only whole U.S. dollars and cents. The depositary will add any fractional cents not distributed to the next sum received for distribution to record holders of depositary shares.

      In the event of a non-cash distribution, the depositary will distribute property to the record holders of depositary shares entitled to it, unless the depositary determines that it is not feasible to make such a distribution, in which case the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders.

Redemption of Depositary Shares

      If we redeem a series of preferred stock represented by depositary shares, then we will give the necessary proceeds to the depositary. The depositary will then redeem the depositary shares using the funds it received from us for the preferred shares. The depositary will notify the record holders of the depositary shares to be redeemed not less than 30 nor more than 60 days before the date fixed for redemption at the holders’ addresses appearing in the depositary’s books. The redemption price per depositary share will be equal to the applicable fraction of the redemption price payable per share for the applicable series of the preferred stock. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem the depositary shares representing the shares of preferred stock on the same day. If fewer than all the depositary shares of a series are to be redeemed, the depositary shares will be selected by lot or ratably as the depositary will decide.

      After the date fixed for redemption, the depositary shares called for redemption will no longer be considered outstanding. Therefore, all your rights as holders of the depositary shares will cease, except that you will still be entitled to receive any cash payable upon the redemption and any money or other property to which you were entitled at the time of redemption.

Voting the Preferred Stock

      How do you vote? The depositary will notify you of any upcoming vote and arrange to deliver our voting materials to you, if you are a holder of record at that time. The record date for determining if you are a holder of depositary shares is the same as the record date for the preferred stock. The materials you will receive will (1) describe the matters to be voted on and (2) explain how you, on a certain date, may instruct the depositary to vote the shares underlying your depositary receipts as you direct. For instructions to be valid, the depositary must receive them on or before the date specified. The depositary will try, as far as practical, to vote the shares as you instruct. We agree to do anything the depositary asks us to do in order to enable it to vote as you instruct. If you do not instruct the depositary how to vote your shares, the depositary will abstain from voting those shares.

Conversion or Exchange

      What happens when we convert preferred stock into other securities, or exchange it for securities of another company? The depositary will convert or exchange all your depositary shares on the same day that the preferred stock underlying your depositary receipts is converted or exchanged. In order for the depositary to do so, we will need to deposit the other stock, common stock or other securities into which the preferred stock is to be converted or for which it will be exchanged.

      The exchange or conversion rate per depositary share will be equal to:

      The following are some more terms of conversions and exchanges that you should keep in mind:

      The depositary shares, as such, cannot be converted or exchanged into other preferred stock, common stock, securities of another issuer or any other securities or property of us. Nevertheless, if so specified in the applicable prospectus supplement, you may be able to surrender the depositary receipts to the depositary with written instructions asking the depositary to instruct us to convert the preferred stock represented by the depositary shares into other shares of preferred stock or common stock of us or to exchange the preferred stock for securities of another issuer. If you have this right, we have agreed that we will cause the conversion or exchange of the preferred stock using the same procedures as we use for the delivery of preferred stock. If you are only converting part of your depositary shares represented by a depositary receipt, new depositary receipts will be issued for any depositary shares that you do not convert or exchange.

Taxation

      As owner of depositary shares, you will be treated for U.S. federal income tax purposes as if you were an owner of the series of preferred stock represented by the depositary shares. Therefore, you will be required to take into account for U.S. federal income tax purposes income and deductions to which you would be entitled if you were a holder of the underlying series of preferred stock. In addition,

Amendment and Termination of the Deposit Agreement

      How may the deposit agreement be amended? We may agree with the depositary to amend the deposit agreement and the form of depositary receipt without your consent at any time. However, if the amendment adds or increases fees or charges or prejudices an important right of holders, it will only become effective with the approval of holders of at least a majority of the affected depositary shares then outstanding. If an amendment becomes effective, and you continue to hold your depositary receipts, you are deemed to agree to the amendment and to be bound by the amended deposit agreement.

      How may the deposit agreement be terminated? The deposit agreement automatically terminates if:

      We may also terminate the deposit agreement at any time we wish. If we do so, the depositary will give you notice of termination not less than 30 days before the termination date. Once you surrender your depositary receipts to the depositary, it will send you the number of whole or fractional shares of the series of preferred stock underlying your depositary receipts.

Charges of Depositary and the Expenses

      We will pay all transfer and other taxes and governmental charges in connection with the existence of the depositary arrangements. We will pay charges of the depositary for the initial deposit of the preferred stock and any redemption. You will pay other transfer and other taxes and governmental charges and the charges that are expressly provided in the deposit agreement to be for your account.

Limitations on Our Obligations and Liability to Holders of Depositary Receipts

      The deposit agreement expressly limits our obligations and the obligations of the depositary to you. It also limits our liability and the liability of the depositary. We and the depositary:

      In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Resignation and Removal of Depositary

      The depositary may resign at any time by notifying us of its election to do so. In addition, we may remove the depositary at any time. The resignation or removal will take effect when we appoint a successor depositary and it accepts the appointment. We must appoint the successor depositary within 60 days after delivery of the notice of resignation or removal and the new depositary must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

Description of Common Stock

      Our authorized share capital consists of 7,010,000,000 shares, of which 7,000,000,000 are common shares having a par value of $1.00 per share and 10,000,000 are preferred shares having a par value of $1.00 per share. As of March 31, 2005, 3,305,320,147 shares of common stock were outstanding. The common stock is listed on the New York Stock Exchange, the Chicago Stock Exchange and the Pacific Stock Exchange under the symbol “SBC”.

      The following briefly summarizes the provisions of our restated certificate of incorporation and our bylaws that are important for you. Both documents are incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and you can obtain them as described below in “Where You Can Find More Information”.

      You should note that some of the provisions of our restated certificate of incorporation and our bylaws may tend to deter any potential unfriendly tender offers or other efforts to obtain control of us. At the same time, these provisions will tend to assure continuity of management and corporate policies and to induce any persons seeking control or a business combination with us to negotiate on terms acceptable to our then-elected board of directors.

General

      All outstanding shares of common stock are, and any shares of common stock offered will, when issued, be fully paid and nonassessable.

      We typically do not issue physical stock certificates. Instead, we record evidence of your stock ownership solely on our corporate records. However, we will issue a physical stock certificate to you if you so request.

      Holders of common stock do not have any conversion, redemption, preemptive or cumulative voting rights. In the event of our dissolution, liquidation or winding-up, common stockholders share ratably in any assets remaining after all creditors are paid in full, including holders of our debt securities and after the liquidation preference of holders of preferred stock has been satisfied.

      The transfer agent for the common stock is EquiServe Trust Company NA, P.O. Box 43010, Providence, Rhode Island 02940-3010.

Dividends

      Common stockholders are entitled to participate equally in dividends when dividends are declared by our board of directors out of funds legally available for dividends.

Voting Rights

      Each holder of common stock is entitled to one vote for each share for all matters voted on by common stockholders. Holders of common stock may not cumulate their votes in the election of directors. Directors are elected by a plurality of the votes cast, while all other matters are determined by a majority of the votes cast, unless otherwise required by law or our restated certificate of incorporation.

      At least 40% of the shares entitled to vote at the meeting must be present in person or by proxy, in order to constitute a quorum.

Board of Directors

      Our bylaws provide that all directors are required to stand for re-election every year. At any meeting of our board of directors, a majority of the total number of the directors constitutes a quorum.

Supermajority Vote for Business Combinations

      Our bylaws also provide that a number of business combinations must be approved by an affirmative vote of the holders of 66²/3% of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class. A vote of approval is required for any of the following business combinations to which an interested stockholder beneficially owning more than ten percent of the voting stock or any of its affiliates is a party:

      The 66²/3% vote of approval is not required if:

Amendment of Bylaws

      Our restated certificate of incorporation requires a two-thirds affirmative vote of the stockholders to amend any bylaw that provides for:

Action without Stockholder Meeting

      Our restated certificate of incorporation also requires that stockholders representing at least two-thirds of the total number of shares must sign a written consent for any action without a meeting of the stockholders.

Plan of Distribution

      We may sell securities to purchasers directly, or through agents, dealers, or underwriters, or through a combination of any of those methods of sale.

      The distribution of the securities may be made from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to these prevailing market prices or at negotiated prices.

      The securities may be sold by us or by one or more of our subsidiaries, including SBC Hedging Management L.L.C., that previously acquired the securities from us, from other of our subsidiaries, from third parties or in the open market. Any such subsidiary may be deemed to be an underwriter under the Securities Act of 1933. SBC Hedging Management L.L.C. is a consolidated subsidiary that owns shares of SBC common stock acquired from a subsidiary that previously acquired them through open market purchases.

Through Agents

      We and the agents designated by us may solicit offers to purchase securities. Agents that participate in the distribution of securities may be deemed underwriters under the Securities Act of 1933. We will name any agent that will participate in the distribution of the securities, and any commission we will pay to it will be described in the prospectus supplement. Any agent will be acting on a “best efforts” basis for the period of its appointment, unless we indicate differently in the prospectus supplement.

To Dealers

      The securities may be sold to a dealer as principal. The dealer may then resell the securities to the public at varying prices determined by it at the time of resale. The dealer may be deemed to be an underwriter under the Securities Act of 1933.

To Underwriters

      The securities may also be sold to one or more underwriters and we will then execute an underwriting agreement with them at the time of sale. The names of the underwriters will be set forth in the prospectus supplement, which will be used by the underwriters to resell the securities.

Convertible, Redeemable and Exchangeable Securities

      If we choose to offer debt securities or preferred stock that is convertible, redeemable or exchangeable into or for third-party securities, we will identify in the applicable prospectus supplement:

      We may enter into indemnification agreements with underwriters, dealers, agents and other persons participating in the distribution of securities, who will then be entitled to indemnification by us against some civil liabilities. The indemnification covers liabilities under the Securities Act.

Delayed Delivery Arrangements

      We may authorize underwriters, dealers or other persons acting as our agents to solicit offers from a number of institutions to purchase securities from us. We will indicate our intention to do this in the prospectus supplement. The contracts for these purchases will provide for payment and delivery on a future date or dates. These institutions include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others and must be approved by us. The obligations of purchasers under these contracts will be unconditional, except that:

      The underwriters, dealers and other persons will not have any responsibility for the validity or performance of these contracts.

Validity of Securities

      Unless otherwise indicated in the prospectus supplement, the validity of the securities offered by this prospectus will be passed upon for us by Mr. James D. Ellis, Senior Executive Vice President and General Counsel of SBC, and for any underwriters, dealers or agents by Sullivan & Cromwell LLP, New York, New York. As of April 21, 2005, Mr. Ellis owned less than 1% of the outstanding shares of SBC. Sullivan & Cromwell LLP from time to time performs legal services for SBC.
