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 a call while accessing the Internet. If your device
supports dual SIM dual VoLTE, you can receive an incoming call on a SIM card while the
other SIM card is being used for a call.
VoLTE also provides you with a faster call connection time and higher quality voice and video
calls.

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 device support 4G and
VoLTE, 4G and VoLTE can be enabled for both SIM cards.
2
Go to Settings > Mobile network > Mobile data. In the network settings area of SIM
1 or SIM 2, turn on the VoLTE calls switch.
This feature may vary depending on your carrier.
