What is VoLTE
VoLTE, short for Voice over Long Term Evolution(LTE), uses your phone's 4G LTE benefits to enable clear call quality using the phone's data connection. This gives you more time to multitask on your phone: talk and chat, talk and post, talk and surf, talk and shop, and more. Enabling VoLTE maximizes mobile data and calls at the same time.
Note: If only mobile data is enabled, you can only enjoy surfing but not making or receiving calls.
