Enable VoLTE to Enjoy HD Calls
Some carriers may not support this feature.
Only dual-SIM phones support both SIM card slots enabling 4G, VoLTE, and VoWiFi.
Open
Settings, and go to Wireless & networks > Mobile network. In the settings
section for SIM 1 or 2 (if supported by your carrier network), you can:
Enable 4G: Turn on 4G. The 4G switch may be unavailable for your device due to your
carrier's settings. This indicates that the 4G network is enabled by default.
Enable VoLTE calling: Turn on VoLTE HD calls.
Enable Wi-Fi calling: Turn on Wi-Fi calling.
After the setting is complete, select the contact you want to call and touch
to make a
video call. You can also touch
on the screen during a voice call to switch to a video call.
