Tata DoCoMO is the first private mobile service provider to announce the date for launching the much anticipated third-generation (3G) mobile services.

The company aims to get a head-start and plans to introduce high-end services such as ultra-fast internet, videoconferencing and other 3G services by Diwali (November 5th 2010), its executive president, mobility business division, Deepak Gulati told ET.

"Japan's NTTDoCoMo has provided technical inputs to make our 3G network world-class. Progressively, NTT will bring various 3G products and services that it offers in Japan - such as i-modeTM, location based services and mobile payment - and give our customers a flavor of tomorrow," Gulati added.

The nine circles where Tatas will launch 3G services include Maharashtra, Gujarat, Karnataka, Kerala, Punjab, Haryana, Uttar Pradesh (West), Rajasthan and Madhya Pradesh. Other leading operators such as Bharti Airtel, Reliance Communications, Vodafone Essar are also slated to introduce 3G services by the year-end. But, these companies are yet to announce the dates.
