Use VoLTE to Make Calls
Voice over LTE (VoLTE) is an IP-based data transmission technology that delivers both call
and data services over a 4G network.
Once VoLTE is enabled, you can make calls while accessing the Internet. If your phone
supports dual SIM dual VoLTE, you can receive an incoming call on a SIM card even when the
other SIM card is already on a call.
VoLTE also provides you with a faster call connection time and higher quality voice and video
calls.
Enable VoLTE
1 Contact your mobile carrier to activate the 4G and VoLTE functions for your SIM card. If
both the primary and secondary SIM card trays of a dual-SIM phone support 4G and
VoLTE, 4G and VoLTE can be enabled for both SIM cards.

Settings > Mobile network > Mobile data. In the network settings area of SIM
1 or SIM 2, turn on the VoLTE HD calls switch.
