Tata Teleservices will invest $2 billion to roll out GSM-based mobile services in India, said a top official.

"The company will invest $2 billion for setting up nationwide services on GSM network over the next two years," Tata Teleservices Managing Director Anil Sardana told reporters in Agra.
The company, which currently offers CDMA platform, plans to launch services in the GSM space by this year end.

Besides, the company plans to expand in the value-added services (VAS) space with the rollout of 3G services in the country next year.

"The VAS contributes about 12 per cent of the revenue in the mobile vertical of the company. We are excited and are developing some new platforms for our existing as well as prospective customers," Tata Teleservices president-VAS Pankaj Sethi told IANS.

Though pricing is a challenge in VAS, the company still hopes to churn out more revenue with the rollout of 3G services.
