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 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.
• The 4G network is used as an example here. If your device supports 5G, the operations
are the same.
• 5G services are only available in some countries and regions.
Make a Video Call
Video calls are only possible when both parties are using VoLTE-activated devices.
1 Open Phone, touch the Contacts tab at the bottom of the screen, then select the
contact you want to call.
2 Touch to make a video call.
During a voice call, you can also touch to switch to a video call.
Use VoWiFi to Make Calls
The VoWiFi function enables you to make calls on a Wi-Fi network. You can even make
VoWiFi calls in Airplane mode.
1 This function requires support from your mobile carrier. Contact your carrier to activate
the VoWiFi function.
2 Go to Phone > > Settings > Wi-Fi Calling, then enable Wi-Fi Calling.
Manage Incoming Calls
You can use the call waiting feature to answer incoming calls when you are already engaged
in a previous call. If you cannot answer a call because your device is faulty or the network
signal is poor, you can also set call forwarding to forward calls to another number or device.
Answer or Reject an Incoming Call
If you receive a call when the screen is locked:
• Drag
right to answer the call.
• Drag left to reject the call.
