Airtel is conducting trial for Voice over LTE (VoLTE) services in five cities, and the services will be launched in the later part of the year, Gopal Vittal, Managing Director and CEO (India and South Asia) of the company, said in New Delhi on Monday, at a press conference to launch Project Next and the Data Roll Over Promise. With this move, Airtel will become only the second operator in the country after Reliance Jio, which started its 4G VoLTE-only network in September last year.

"We are in the midst of trials. We are already doing trials in five cities. Towards the latter part of the year we should be able to launch it," Vittal told reporters. 4G VoLTE will allow the operator to offer both voice and data without switching between bands, and may also help compete with Reliance Jio and its free calling services on an even keel.

As we mentioned, Airtel at the New Delhi press conference also launched its Data Roll Over Promise, which in essence gives its postpaid subscribers the ability to carry forward unused data from their current billing cycle to the next billing cycle.

"This new-to-the-world innovation will ensure zero data wastage for customers and brings unmatched value to the Airtel Postpaid proposition." A customer can carry forward up to 200GB of data, Airtel said. Customers will be able to keep track of their data on the MyAirtel app.
