Airtel launches Voice over LTE in West Bengal and Sikkim to take on Jio

Telecom major Bharti Airtel on Wednesday announced the launch of Voice over LTE (VoLTE) services across West Bengal and Sikkim.

The New Delhi-headquartered company had rolled out the high-speed wireless communication technology in Kolkata earlier this year. Airtel has been ramping up its 4G capacity in both the states, the company said in a release.

"There will be no additional data charges for VoLTE... In case of non-availability of the 4G network, VoLTE calls automatically fall back on the 3G/2G network," the release said.
