MIUI 12.5 Tip: How to activate VoWiFi in Xiaomi smartphone

Nowadays, Phone calls have been evolved in such a way that we don’t even need to have mobile coverage to make or receive one. All thanks to VoWiFi, which allows a Xiaomi or other smartphone user to make a call without a network.

With VoWiFi, we can not only receive high-quality phone calls, but we also won’t need mobile coverage in relation to phone calls offered through traditional GSM networks.


It allows you to perform the calling actions in every condition until you enable airplane mode.

What is VoWiFi:

You may already be familiar with VoLTE, which is short for voice-over LTE (a 4G standard). While it uses a data network, VoWiFi depends on the WiFi network your device is connected to.

Both VoWiFi and VoLTE can work together. If WiFi gets disconnected, the call will be on your mobile data. Similar to VoLTE, VoWiFi also shows an indicator in the status bar of the phone.
