Tata Teleservices Maharashtra (TTML), the listed entity of the Tata Group engaged in offering CDMA-based mobile services in Mumbai and the rest of Maharashtra including Goa, is set to roll out its GSM-based mobile services in Mumbai on Thursday, according to a media report.

TTML will launch the services under the Tata DoCoMo brand in the crowded Mumbai circle, becoming the tenth GSM operate in the metro. Among the existing operators, Vodafone Essar is the market leader and has 4.6 million users, followed by Reliance Communications, which offers both CDMA and GSM services. TTML has so far been only a CDMA provider and has 2.5 million users in Mumbai, the report added.

TTML has drawn up an Rs 1,000-crore capital expenditure plan for the GSM foray in Mumbai Maharashtra services and is expected to offer the services at one paise per second, giving an initial push to its services. The GSM services will have an added advantage, thanks to the company’s CDMA infrastructure in the region.

The Tata Group has already begun GSM services in Chennai, Tamil Nadu, Karnataka and Andhra Pradesh through Tata Teleservices, the group’s unlisted telecom entity, which provides CDMA services in 20 circles.

While GSM services would be launched in Mumbai on August 6, the services in the rest of Maharashtra and Goa would kick off by the end of the month, the report said.
