As a part of the nationwide roll out of its GSM services, Anil Ambani-led Reliance Communications has finally launched its GSM Services in Mumbai.

With the latest move, Reliance Communications has became the first private CDMA service provider in India to provide GSM services.

It may be noted that few days earlier, the company had announced the launch of its GSM services across 11,000 towns in the country.

The company has offered new GSM SIM Card at just only Rs 25 along with free talk-time worth Rs 900 spread over three months. However, the SIM card has the validity of six months.

An official release stated that, new subscribers would get Rs 10 talk-time every day for the first 90 days and has offered tariffs of Re one a minute for local calls and STD would cost Rs 1.50 per minute on any network.

But after consuming Rs 10 during the day, the subscribers can choose option of top up cards with denominations ranging between Rs 10 to Rs 500 with the same tariffs.

In addition, despite free-talk time, the Reliance GSM customers will also get unlimited calling on Reliance network (both GSM and CDMA) absolutely free between 10 PM to 6 AM through out Mumbai, Maharashtra and Goa.

Sources revealed that the company is presently working out various other pre-paid tariff plans, which it would announce during the next few weeks.

Tata group’s Tata Teleservices, one of the leading CDMA operator, also has plans to roll out its GSM services this year. Market experts believe that the latest move by the Reliance Group would trigger another tariff war among mobile operators.
