India\'s mobile operator Bharti Airtel has started 4G LTE services for mobile in Bengaluru, where Apple iPhone 5s or 5c users can get 4G at current 3G prices, LteWorld reported on Friday. Customers need only change their SIM to a 4G SIM to start the service.

Airtel prepaid and postpaid customers can access 4G on mobile, while those with 2G/GPRS data plans can also choose any of the 3G plans available and get 4G speeds. Airtel also offers a new 4G plan for heavy data users that provides 10 GB 4G data for Rs. 1000 ($16). Data browsing is on the 4G network, while voice calls are routed on 2G/3G seamlessly with circuit switched fall back (CSFB) technology.
