If network reception or signal strength on the Xiaomi smartphone is weak, we can activate WiFi calls to make calls over an existing WiFi network. Wi-Fi calling must be supported by the respective network provider.
Note: If the function cannot be found under the SIM card settings, we can enable it by entering the following combination *#*#869434#*#*. This must be entered via the dial pad of the phone app.
