Gradually, the service will be expanded to the rest of the country, the statement added.
VoLTE is truly an IP based voice call technology which is especially designed to ensure HD quality voice calls. VoLTE treats voice as just another application that rides on the LTE data network. This advanced technology will allow customers to have their calls set up within only 3-4 seconds, which is 40-50 per cent faster than traditional 2G or 3G voice calls.
The benefits of using VoLTE technology doesn't end here. According to a GSMA study (The global trade body of all mobile operators), customers get 40 per cent more battery life using VoLTE compared to calls made through OTTs (Over the Top), like, whatsapp, viber, imo, etc.
In order to have end to end service experience, the person making a call and the person receiving the call need to have VoLTE supported and enabled 4G handsets and VoLTE activated 4G SIM card in their handset and be present in the VoLTE coverage areas.
