How do I know VoLTE works?
If you're calling with VoLTE it means that you're using the 4G (LTE) network during the call, instead of 2G or 3G. Because of this, you should be able to see the 4G symbol on your phone while being in a call. You should also be able to use your mobile data during the call.
Keep in mind that the phone automatically switches between 2G/3G and 4G (LTE) depending on your current connection to each network.
