          TURKCELL PROVIDES UPDATE REGARDING THE NEW ICC RULING ON THE
                          DEFINITION OF GROSS REVENUE


Istanbul, Turkey: January 9, 2004--Turkcell (NYSE:TKC, ISE: TCELL), the leading
provider of mobile communications services in Turkey, today announced that the
International Court of Arbitration of the International Chamber of Commerce
("ICC") has issued its verdict regarding Turkcell's petition concerning the
definition of the items that should be included in the "gross revenue" item used
in the calculation of the 15% Treasury share payment.

The ICC's decision stated that all the revenue items originating from
telecommunication services should be included in the calculation of gross
revenue, while the taxes collected by Turkcell under its "tax responsibility"
should be excluded. Turkcell continues to evaluate its legal options.
