VoLTE not working on Samsung A21s

Might be update your phone

This can improve the quality of your calls and save battery life.



VoLTE is only for 4G mobile networks and will usually turn off when you connect to WiFi. If your network supports VoWifi, it should switch to VoWifi when you connect to WiFi


If you don't see VoLTE toggle, that would mean your phone hasn't got the carrier specific VoLTE config's. This is in the system level of your phone's software. "CarrierConfig" is the system app that has carrier specific config's stored. The app includes config settings for all carriers worldwide. It depends on the Phone manufacturer to get the app updated in each of thier models.

Then start airoplane mode for 30 seconds and turn it off again.

If above method failed, then reboot your device and do it again.

And of it failed again then goto other location..

If it is still not working then bad luck for you, you have a faulty device, very sad 😭. Please don't cry.
