             TURKCELL ANNOUNCES FINAL SETTLEMENT OF SECURITIES CLASS
                                 ACTION LAWSUIT

Istanbul, Turkey: April 20, 2004 - Turkcell (NYSE: TKC, ISE: TCELL), the leading
provider of mobile communications in Turkey, announced today that a federal
judge has approved the settlement of the consolidated securities class action
lawsuit filed against the Company and several of its past and present officers
and directors in the U.S. District Court for the Southern District of New York.
Under the terms of the settlement, all claims against the Company have now been
dismissed without admission of liability or wrongdoing. The shareholder class is
receiving a cash payment of $19.2 million.

This purported class action lawsuit was initiated in the United States District
Court for the Southern District of New York against Turkcell and two of its past
and present officers and directors on November 22, 2000.

Although, Turkcell management believes that plaintiff's claims are without
merit, the company is pleased to put the uncertainty and expense of the class
action litigation behind and believe that the decision to settle is in the best
interest of our shareholders.

                                                           FOR IMMEDIATE RELEASE


            TURKCELL WILL RECOMMEND 20% DIVIDEND DISTRIBUTION AT THE
                             ANNUAL GENERAL MEETING


Istanbul, Turkey: April 26, 2004 - Turkcell (NYSE: TKC, ISE: TCELL), the leading
provider of mobile communications in Turkey, announced today that the Turkcell
Board of Directors has decided to recommend a 20% dividend distribution, from
its 2003 distributable net income, to its shareholders. The proposed dividend
will be in the form of a 50% cash and 50% share distribution. The gross
distributable dividend after legal reserves amounts to TL236,317 billion
(US$170.2 million*). Accordingly, the total gross cash dividend of TL118,159
billion (US$85.1 million*) will be distributed to its shareholders, representing
a cash dividend of TL236 (USc 0.02*) per ordinary share and approximately
TL590,000 (USc42.5*) per ADR. Turkcell shareholders could be subject to a
withholding tax deduction, of up to 10%, from the gross dividend depending on
the applicable tax regulations. The stock dividend will be 23.6% per share.

Previously, Turkcell was not legally eligible to distribute dividends under
Turkish regulations because of its accumulated balance sheet loss under Turkish
Accounting Standards. However, new Turkish Accounting Standards and Turkcell's
2003 net profit has enabled Turkcell to distribute a dividend. Accordingly,
Turkcell will be able to distribute a dividend following the approval of its
shareholders at its Annual General Meeting.

April 22, 2004.
