Bharti Airtel  launched 3G service in Delhi circle, enabling subscribers to access high speed internet and video telephony.

The company launched its third Generation of Mobile services on the back of a robust network powered by over 1,800 3G sites in the National Capital Region spanning Delhi, Gurgaon, Faridabad and Noida.

Bharti Airtel is the third private operator after Tata Teleservices and Reliance Communications to launch 3G services in the country. State—run BSNL and MTNL are also offering these high speed services.

Besides, Airtel’s 3G services are already available in the seven cities - Bengaluru, Chennai, Coimbatore, Mysore, Manipal, Udipi and Jaipur - and will be operational in all 13 3G—licence circles by March 2011.

“Today, with just over a month since our rollout began, our 3G network covers around half a million customers and has 4,500 sites which is available across seven cities,” Bharti Airtel President (Mobile Services) Atul Bindal told reporters here.

“We are definitely witnessing the tipping point of non—voice and data explosion in this country and will be bringing the airtel 3G advantage pan—India soon as promised,” he said.

Airtel 3G will allow customers to enjoy a variety of exciting service offerings including Mobile TV, Video Calls, high—speed internet and video capabilities on social networks.

Further, a wide range of live and on—demand TV channels as well as shows would be available on Airtel 3G Mobile TV at an affordable price of Rs 40 for 20 minutes per week, the company said.

Bharti Airtel had bagged 3G spectrum in 13 out of the 22 telecom circles for Rs 12,295 crore through an auction held last year.
