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.
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.

• The 4G network is used as an example here. If your device supports 5G, the operations
are the same.
