                                                           FOR IMMEDIATE RELEASE

            TURKCELL INCREASES SUBSCRIBER BASE BY 29% TO 15.7 MILLION

Istanbul, Turkey: January 14, 2003--Turkcell (NYSE:TKC, ISE: TCELL), the leading
provider of mobile communications services in Turkey, today announced a 29%
increase in its overall customer base to 15.7 million as of December 31, 2002,
from 12.2 million subscribers as of December 31, 2001.

In the last quarter of 2002, Turkcell acquired approximately 843,000 net new
subscribers, raising the total number of its mobile subscribers to 15.7 million
as of December 31, 2002, up from 14.9 million subscribers at September 30, 2002.
The overall subscriber base consisted of 4.7 million postpaid and 11.0 million
prepaid subscribers as of year-end 2002. New gross subscribers acquired in 2002
consisted of 90% prepaid and 10% postpaid subscribers.

Mr. Muzaffer Akpinar, CEO, noted that Turkcell's strong business dynamics
combined with improved consumer sentiment in 2002 provided the Company with
increased subscriber growth compared to 2001, despite continued political and
economic volatility in 2002. "Our subscriber growth in 2002 was ahead of our
initial expectations and we were able to acquire the majority of new subscribers
in the Turkish mobile market in 2002 as a result of our customer focused
strategies, consumer friendly services and innovative business approach" Mr.
Akpinar said.

Turkcell targets a modest growth in its subscriber base in 2003. However,
further instability in the region, agressive pricing by its competitors and
potential change in Turkey's macroeconomic policies may impact Turkcell's
business plan in 2003. Realization of one or more of these risks may result in a
less favorable business environment for Turkcell. Turkcell plans to monitor the
market conditions carefully and take necessary actions to remain competitive and
maintain its leadership position in the market during 2003.
