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.
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.
Features may vary depending on your carrier.
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.
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 phone 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.
• Touch to reject the call and reply with an SMS message.
• Touch to set a callback reminder.
