Industry sources said that the tests were in advanced stages and the services would be launched in a month.
Airtel VoLTE, which works over 4G, will offer customers HD quality voice calls along with faster call set up time.
The sources said that customers could call any mobile or landline using Airtel VoLTE. There would be no additional data charges for using VoLTE and calls would be billed according to existing plan or pack benefits.
“The differentiator in Airtel VoLTE is seamless connectivity,” the source said. Even in the case of non-availability of 4G, Airtel VoLTE calls will automatically fall back on 3G or 2G network so that the call does not drop.
Airtel VoLTE will also allow customers to continue with their data sessions at 4G speeds while the call is in progress.
How to get Airtel VoLTE
Ensure the device is VoLTE compatible and has a Airtel 4G SIM. If the SIM does not support 4G, customers can get a 4G SIM at Airtel outlets.
Customers with dual-SIM handsets have to ensure that the Airtel 4G SIM has been inserted in the data SIM slot/slot 1 and network mode has been set as 4G/3G/2G (Auto).
Airtel has already launched VoLTE services in Mumbai.
