With VoLTE calls, which will use 4G data network and hence will be effectively free for consumers, Airtel hopes to take on Jio. Currently Jio is the only telecom operator offering VoLTE calls. The report in the Economic Times, a daily business newspaper, says that Mumbai will be the first city where Airtel users will get VoLTE calls feature. To target feature phone users and woo them with free calls, Jio recently launched the "free" JioPhone. It has been rumoured that by the end of this year, Airtel will also come out with its own 4G feature phone that will support free VoLTE calls.
