Wi-Fi Calling: the free fix for indoor dead spots
When mast signal cannot reach your sofa, your broadband can carry the call instead. It is free, built into modern phones, and chronically under-used.

What it is
Wi-Fi Calling routes ordinary calls and texts over your broadband connection when mobile signal is weak, using your normal number. Callers notice nothing. It is included at no extra cost on the major UK networks for compatible handsets — no app required.
Enabling it
- iPhone: Settings › Mobile Data (or Cellular) › Wi-Fi Calling › on.
- Android: typically Settings › Connections or Network › Wi-Fi Calling — wording varies by manufacturer.
- If the toggle is missing, your network may need to provision it, your handset may be incompatible, or (on virtual networks) the brand may not support the feature — confirm with your provider's official support.
What it fixes — and what it does not
- Fixes: dropped calls indoors, one-bar bedrooms, thick-walled and rural properties with decent broadband.
- Does not fix: mobile data speeds outdoors, coverage on the move, or a fundamentally poor network match for your area — for that, see the coverage guide and consider switching.
Virtual-network users: Wi-Fi Calling support varies by brand even on the same host network. Check your own brand's official position before assuming.
