NEW YORK STOCK EXCHANGE

Istanbul, Turkey: February 1, 2005 – Turkcell (NYSE: TKC, ISE: TCELL), the leading provider of mobile communications in Turkey, announced today that trading in Turkcell was suspended on the Istanbul Stock Exchange today.

Even though we informed the Istanbul Stock Exchange that Turkcell is not a party to the agreements related to Cukurova Group’s option to buy Turkcell shares, and that we do not have any information at this time, the trading suspension continued all day since the Istanbul Stock Exchange is expecting further information from other parties subject to the agreement.
