One of the largest telecom operators in India, Airtel has been facing some stiff competition from Reliance Jio lately. Notably, Reliance Jio has an all-IP network with support for VoLTE calls. While Airtel has started implementing Voice over LTE in some telecom circles, it has now started a new Beta Program to expand the service in more states to strengthen its foothold. The operator is offering free data benefits to users who sign up to participate in its VoLTE Beta Program.
