KOLKATA: 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 4G network, VoLTE calls automatically fall back on 3G/2G network," the release said.
