                                                           FOR IMMEDIATE RELEASE


           TURKCELL PROVIDES UPDATE ON THE APPROVAL PROCESS OF ITS GSM
                           LICENSE AGREEMENT IN IRAN


Istanbul, Turkey: September 27, 2004 - Turkcell (NYSE: TKC, ISE: TCELL), the
leading provider of mobile communications in Turkey, announced today an update
on the approval process of its GSM license agreement in Iran.

Previously, Turkcell announced that although the GSM license agreement was
signed between Irancell, the company that would carry out the GSM operations in
Iran, and the Iranian government, Irancell would not become a licensed GSM
operator until the license fee of (euro)300 million was paid.

Following talks between Turkcell and Iranian officials, Turkcell has been
informed that the Iranian Parliament has clarified that the Iranian law, which
requires the approval of Parliament for investments with more than 50.1% foreign
ownership, is applicable to Turkcell's GSM investment in Iran.

Accordingly, Irancell must receive the Iranian Parliament's approval prior to
the payment of the (euro)300 million of license fee in order to become the
second licensed GSM operator in Iran.

Turkcell will make a further announcement once the GSM license has been
transferred to Irancell.
