One of the leading mobile telecom operators in the country, Airtel rolled out its VoLTE services in India in 2017, after strong competition from Reliance Jio which runs its entire network on the VoLTE system. A year later, Airtel has announced that over 200 4G smartphones available in India support the Airtel VoLTE network, allowing users to place and receive VoLTE calls on the company’s network.
Numerous major brands in India have geared their software to support voice calls using VoLTE on the Airtel 4G network in India. These brands include Oppo, OnePlus, Vivo, Apple, Samsung, Nokia, Xiaomi, Panasonic, Lava and Karbonn, which have their popular smartphones now supporting Airtel VoLTE at the software level. Users of these smartphones on the Airtel network therefore have the option to place VoLTE calls where supported.
Apart from Airtel, Reliance Jio, Vodafone and Idea Cellular also offer 4G VoLTE services, with a large number of smartphones supported. While there is near-universal support for VoLTE for Reliance Jio (on 4G devices), smartphone makers have had to manually add support for VoLTE on other networks. The advantage of VoLTE is better audio quality on calls, since the network is able to handle the larger volume of the connection thanks to the higher speeds and data transfer capabilities on 4G networks.

Users are thus able to enjoy better call quality when placing a call to a user that also has a VoLTE-enabled phone and connection. With increasing support on the Airtel network, this will improve the quality of voice calls for users. Note that VoLTE usually needs to be enabled by the user on the smartphone, and if it isn’t enabled, the phone will switch to 3G or 2G networks for voice calls by default.
