Short answer

Open Settings, tap Network & internet, SIMs, your SIM, then Wi-Fi calling and switch it on. On Samsung, open Settings, Connections and switch on Wi-Fi Calling. Your network and tariff must support it.

Wi-Fi calling lets normal calls and texts go over a Wi-Fi network when the mobile signal is weak, such as in a basement or a building with thick walls. You keep your number and use the normal Phone app.

Menu names below are from Google Pixel phones on a recent Android version. Samsung, Xiaomi and other brands rename some of them, so the Samsung name is given where it differs. The pictures are simplified diagrams of the screen, not screenshots.

    During a call over Wi-Fi, the call notification says "Wi-Fi calling" or "Internet call". Many phones also show a small Wi-Fi calling icon in the status bar.

Good to know

If the option is missing, your network or tariff does not support Wi-Fi calling on this phone model. Phones bought from another country or network are the most likely to lack it.

Calls are charged as normal calls from your home country. Check your network's terms before using it abroad.

Some office and hotel Wi-Fi networks block it.

In short: Settings, Network & internet, SIMs, your SIM, Wi-Fi calling.
