Bharti Airtel launches VoLTE services in Mumbai

India's largest telecom service provider Bharti Airtel has finally announced its Voice over LTE (VoLTE) services in Mumbai and it becomes the second operator in the country to launch VoLTE services after Reliance Jio.

Airtel VoLTE, which works over 4G, will offer customers HD quality voice calls along with faster call set up time, the company said in a statement.

Abhay Savargaonkar, Director - Networks, Bharti Airtel said, "This is a significant milestone in Airtel's network transformation journey under Project Leap. Airtel has built a world-class 4G network across India and with the VoLTE compatible device ecosystem beginning to mature, we believe it's the right time to enable VoLTE calling as part of our service portfolio."

Savargaonkar said that "Over the next few months, we will rapidly accelerate the deployment of VoLTE to cover all key geographies to bring HD quality calling to our customers. We keenly look forward to our device partners enabling Airtel VoLTE on their smartphones."

Airtel VoLTE will be available on popular 4G/LTE enabled mobile devices, which must have an Airtel 4G SIM.

Customers can call any mobile, landline network using Airtel VoLTE. There will be no additional data charges for VoLTE and calls will be billed as per existing plan or packs benefits.

The company said that in the case of non-availability of 4G, Airtel VoLTE calls will automatically fall back on the 3G/2G network to ensure that customers continue to stay connected at all times. Airtel VoLTE will also allow customers to continue with their data sessions at 4G speeds while the call is in progress.
