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.

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.
