Turkcell Introduces a Platform Open to all Banks Enabling Easiest Money Transfer and Payment Through Launch of Cep-T ParaCard with Garanti Bank

ISTANBUL, June 1, 2011 -

Turkcell (NYSE:TKC, ISE: TCELL), the leading communications
and technology company in Turkey is delighted to announce that together with
Garanti Bank, the leading bank in payment systems, it has launched a
co-branded prepaid card named "Cep-T ParaCard".

The Cep-T ParaCard is a no name prepaid card with MasterCard
logo issued by Garanti Bank. Turkcell customers can purchase the Cep-T
ParaCard and subscribe to the Cep-T Para service from any Turkcell
Communication Center (TIMs) and top-up money to the card via Garanti POS
machines at TIMs, or from any Garanti ATM. Customers can use their cards for
payments worldwide wherever MasterCard is accepted. The Cep-T Para service is
a SIM based secure service that can be used with any handset. Cep-T Para
subscribers can use this service to transfer money to any operator's mobile
subscribers. Recipients can withdraw their money instantly from Garanti ATMs
by simply using a secure code sent to them, without a debit card. Subscribers
can also use the service to top-up their prepaid lines.

Garanti Bank CEO Ergun Ozen has said that "We are starting a
new era with the Cep-T ParaCard, a joint project with Turkcell. This new
product integrates the mobile world with banking to provide privileges to
mobile users. 2/3 of the population in Turkey does not utilize banking
services, either due to their age or income. We target to reach 3 million
people through our prepaid ParaCard, and 1.5 million people via Cep-T
ParaCard within 3 years."

Turkcell CEO Sureyya Ciliv has said that "Turkcell is always
proud to introduce another first for mobile finance services. We aim to
provide the advantage of mobility to those who cannot make full use of the
banking system. Accordingly, we have introduced Cep-T Para as a mobile
financial service platform available for all banks to facilitate our
customers' daily lives. We also provide the banks an alternative platform, on
which they can reach nearly 20 million people currently beyond the financial
system. We believe that Cep-T Para, which combines the advantages of mobility
with financial operations, will become an indispensible part of our lives. We
expect to reach 5 million users, including 2 million newcomers to the banking
system within 3 years."
