Wi-Fi Calling and VoLTE: turn them on for better calls indoors
Wi-Fi Calling lets your phone make normal calls and texts over a Wi-Fi network instead of the mobile signal, so weak indoor coverage stops mattering. VoLTE (4G Calling) keeps calls on faster 4G. Both are free on most UK networks and switched on in your phone settings — together they’re the best fix for poor mobile signal at home.

If your mobile signal is weak at home, these two free settings are the fix. Here’s what they do and how to switch them on.
What they do
- Wi-Fi Calling routes your calls and texts over a Wi-Fi network. As long as your home broadband is decent, weak mobile signal stops mattering indoors.
- VoLTE / 4G Calling carries calls over 4G rather than older networks — faster to connect, clearer, and you can use data mid-call.
Turn both on for the best results.
How to turn on Wi-Fi Calling
iPhone: Settings → Mobile/Cellular → Wi-Fi Calling → turn on.
Android: Settings → Network & internet → search for “Wi-Fi Calling”, or open your phone/calling app’s settings. The exact path varies by handset and network.
How to turn on VoLTE / 4G Calling
iPhone: Settings → Mobile/Cellular → Mobile Data Options → Voice & Data → enable 4G/VoLTE.
Android: Settings → Network & internet → SIMs → turn on “VoLTE” or “4G Calling”.
If you don’t see the option, your plan or handset may not support it yet — your network can confirm.
Make sure your Wi-Fi is strong
Wi-Fi Calling is only as good as the Wi-Fi where you are. If calls over Wi-Fi still drop, improve your coverage — see better Wi-Fi in every room — or run the fix mobile signal tool.
Frequently asked questions
What is Wi-Fi Calling?
Wi-Fi Calling lets your phone make and receive normal calls and texts over a Wi-Fi network rather than the mobile network. It’s free on most UK networks and is the best fix for weak indoor mobile signal.
What is VoLTE or 4G Calling?
VoLTE (Voice over LTE), often called 4G Calling, carries your calls over the 4G network instead of older 2G/3G. It connects faster, sounds clearer, and lets you use data during a call.
Does Wi-Fi Calling cost extra?
On most UK networks it’s free and calls come out of your normal allowance. Check your provider, but there’s usually nothing extra to pay.
