Wi‑Fi Calling lets you make and receive calls over Wi‑Fi when your mobile signal is weak or unavailable. You need to have Wi‑Fi Calling switched on in your phone settings and be connected to a Wi‑Fi network that can support voice calls.
Wi‑Fi Calling only works in the UK.
Check if your device shows the Wi‑Fi Calling setting
If you can’t see the Wi‑Fi Calling option on your phone, you may need to update to the latest software.
Check how to do this for your phone.
If you are using Wi‑Fi Calling for the first time, restart your phone to allow the Wi‑Fi Calling indicator to appear.
Check why the Wi‑Fi Calling indicator is missing
You won’t see the Wi‑Fi Calling indicator if your Wi‑Fi signal is too weak or can’t support a call. This can happen if the connection is busy or unstable.
If this happens at home, check your internet connection by opening a webpage or using another device connected to the same Wi‑Fi.

Improve poor call quality
For the best experience, we recommend a minimum broadband speed of 1Mbps. If your calls are poor quality, your broadband may be too slow, or your connection might be busy with things like streaming.
If you are using public Wi‑Fi, congestion or low speeds can affect call quality. Make sure you are logged in to the Wi‑Fi network, as some hotspots log you out automatically. If the connection stays poor, turn off Wi‑Fi Calling.
Change settings for call waiting, call forwarding or withhold number
You can’t switch on call waiting, call forwarding or withhold number while you are using Wi‑Fi Calling without mobile signal. Set these up before using Wi‑Fi Calling and they’ll continue to work.
You can’t turn off call forwarding while you are on Wi‑Fi Calling, even if you have mobile coverage.
