RCom has launched the service in three metros -- Delhi, Mumbai and Kolkata -- and in Chandigarh.
"By next three months we will launch it in the remaining nine circles for which the company has spectrum. Our tariffs will be affordable, simple and transparent based on try and buy pricing proposition," RCom's President and CEO (Wireless Business) Syed Safawi said.
RCom had bagged 3G spectrum in 13 circles for which it had paid about Rs 8,585.04 crore (Rs 85.85 billion) to the government. RCom is among the top three with highest 3G-enabled coverage.
TTSL, which bagged 3G spectrum in nine circles, has already started 3 G service from Diwali this year.
Besides, the private telcos, state-owned BSNL and MTNL, who had got 3G spectrum ahead of the private operators, already offers 3G service in the country.
