VoLTE or Voice over LTE is a service that allows you to make and receive voice calls via LTE using an LTE-capable phone, unlike the current practice where calls go through 2G or 3G mobile networks.

• You will be able to stay online on 4G/LTE network with your data applications, like Waze, online games, etc. even when making or receiving a call.

• This means you can simultaneously be in a voice call, while actively using high-speed data for other applications.

VoLTE uses LTE network, while Wi-Fi Calling uses your Wi-Fi network for extended network coverage and enhanced voice & SMS experience.
