Android menu paths differ by manufacturer, so configure the correct SIM and verify support with the network rather than following one universal path.
Before changing settings
Install current software, check the network’s device list and confirm that Wi‑Fi Calling is active on the plan. Imported variants may contain the hardware but lack the operator profile needed in the UK.
Common menu routes
| Phone family | Typical route |
|---|---|
| Google Pixel | Settings → Network & internet → SIMs → selected SIM → Wi‑Fi Calling |
| Samsung Galaxy | Phone app → menu → Settings → Wi‑Fi Calling, or Settings → Connections |
| Other Android phones | Search Settings for “Wi‑Fi Calling” and verify the route in the operator’s device guide |
Enable and test
- Connect to trusted Wi‑Fi.
- Choose the correct SIM or eSIM if the phone has two lines.
- Enable Wi‑Fi Calling and review any emergency information.
- Restart if the network requests it.
- Make and receive an ordinary call where mobile reception is weak.
If the switch is absent
Check updates and operator provisioning first. Do not use hidden dialler codes, unofficial configuration apps or firmware from another region; these can break calling, updates or security.
Choose a calling preference carefully
Some Android phones offer “Wi‑Fi preferred” or “mobile network preferred”. Use Wi‑Fi preferred only where the local Wi‑Fi is consistently stable; otherwise the phone may remain on a weak access point. After changing the preference, test both while stationary and when moving between rooms.
After a SIM or network change
Recheck the setting after replacing a SIM, moving an eSIM or changing provider. The menu may remain visible even though the new line has not been provisioned, or it may disappear until carrier configuration is updated. Make a fresh incoming and outgoing call rather than assuming the old setup carried across.
A real-world check that prevents the common mistake
Use the exact Pixel, Samsung or manufacturer path rather than a generic Android menu. If the option is absent, confirm provisioning and firmware before resetting anything. Once enabled, test an ordinary call on the intended line with weak mobile signal and repeat after a restart.
- Check battery-saving or VPN behaviour if calls are unstable.
- Test each Dual-SIM line separately.
- Record the device model and software for provider support.
