Sistema, the largest public diversified corporation in Russia, acquired a 10% stake in Shyam Telelink for a total cash consideration of US$11.4 million at the end of September 2007.

In August 2008, they got a pan-India start-up spectrum to start their mobile service operations in the country.

They provide mobile services based on CDMA technology under the brand name MTS India and gave contracts to ZTE and Huawei for network expansion.

As a result of the deal, Reliance acquired nearly 9 million subscribers, as well as SSTL's spectrum in the 850 MHz band.
