Moscow, Russian Federation – Mobile TeleSystems OJSC (“MTS” or the “Company” – NYSE: MBT), the leading telecommunications provider in Russia and the CIS, announces a strategic initiative with Microsoft, the global IT leader, to promote innovative mobile solutions by launching Windows 8 “ Ecosystem Demo Zones” in MTS retail stores.

For the first time in Russia and Central and Eastern Europe, various Windows 8 mobile devices, including software and accessories, will be available to customers at MTS retail stores. In Moscow, St. Petersburg and Yekaterinburg, 20 “Demo Zones” will allow customers to test Windows 8 smartphones, notebooks and tablets.

Consumers will be able to purchase products bundled with data plans immediately.

“We have reimagined Windows. Now, you will be able to buy stunning Windows 8 laptops, tablets and phones that share the same iconic look, access the same cloud services and all work together to keep you connected to the people and information most important to you,” said Microsoft CEO Steve Ballmer. “To show people the phenomenal, full Windows experience we are thrilled join one of our most strategic partners, MTS, and open the first Windows ecosystem demo zones in Russia.”
