Bharti Airtel will launch its 4G services for mobile devices in Bangalore later this month. Moreover, the company will be offering users 4G plans at the 3G data rates. If rolled out, it will be the first time 4G experience will be available on mobile platforms.

However, Airtel users with 4G-supported smartphones, migrating to 4G, will have to get a new SIM card. "Existing 3G plans will apply to users who will be migrated to 4G for no extra cost. However, they will have to get a SIM card replacement. Voice networks will continue to run on 2G and 3G networks," Srini Gopalan, Bharti Airtel's director for consumer business is quoted as saying.

Currently, only few phones such as the iPhone 5S and iPhone 5C support the 2300 MHz frequency band on which 4G is being offered.

"We expect more devices will soon come enabled for this band. China has just allocated 4G spectrum in the 2300 MHz band to its operators, so there should be a lot more manufacturing of such devices," Srini Gopalan, director of consumer business in Bharti Airtel India, added.

According to the Airtel official, users on 4G network will be able to download 10 standard movies within 30 minutes.
