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.

both the primary and secondary SIM card trays of a dual-SIM phone support 4G and
