                 THE TELECOMMUNICATION AUTHORITY FINES TURKCELL


Istanbul, Turkey: December 29, 2003--Turkcell (NYSE:TKC, ISE: TCELL), the
leading provider of mobile communications services in Turkey, today announced
that the Telecommunication Authority ("TA") has fined Turkcell, claiming that
Turkcell made inadequate annual frequency usage fee payments.

According to the related regulations, frequency usage fee claims should arise
only for those subscribers who actively use their mobile phones. However, the TA
claimed that Turkcell also should pay these fees for those subscribers whose
inactivity may be temporary. The TA demands TL16,005.3 billion (US$11.3mn) for
insufficient payment and an interest charge amounting to TL10,761.8 billion
(US$7.6mn). Moreover, the TA ordered us to pay an additional amount of
TL63,461.6 billion (US$45.1mn) as an administrative penalty. Turkcell believes
that the TA's calculations of the required frequency fee payments are unfair and
not balanced. Turkcell believes that the TA's decision is due to a
misinterpretation of the applicable regulations and that the magnitude of the
administrative penalty is surprising. The total amount demanded by the TA totals
TL90,228.7 billion (US$64.1mn). Turkcell will take the necessary legal actions
against the TA's ruling.
