       TURKCELL PROVIDES UPDATE ON THE PROGRESS OF ITS INVESTMENT IN IRAN


Istanbul, Turkey: September 23, 2004 - Turkcell (NYSE: TKC, ISE: TCELL), the
leading provider of mobile communications in Turkey, announced today an update
on its operations in Iran in the light of recent media reports stating that the
GSM license agreement had been signed establishing Turkcell as the second GSM
operator in Iran.

The GSM license agreement has been signed between Irancell, the company that
will carry out the GSM operations in Iran, and the Iranian government. However,
Irancell will not become a licensed GSM operator until the license fee of
(euro)300 million is paid.

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