Automatically switch iPhone to Wi-Fi at home

The T-Mobile signal is weak at our house. You would think the iPhone 13 would be smart enough to switch from cellular to Wi-Fi but it isn't.

Is there a way to automatically toggle to Wi-Fi at a location and have cellular back on when leaving? Or is there some other method to toggle the call to Wi-Fi and leave cellular on.

All too often I receive a call at home and realize the connection is bad and have to ask the person to call me back so I can turn off cellular. And then I may forget to turn it back on when I leave. This has become a bit more difficult with iOS 18 as the cellular icon on the swipe down screen has become smaller and more choices are offered? Signal is one to two bars in house depending on where in house.

iPhone 13 Pro, iOS 18

Any time you have a Wi-Fi connection it will automatically be used over the cellular connection for data. the “gotcha” is that when the phone is locked (asleep) Wi-Fi turns off to save battery energy unless the phone is plugged in.

If you have Wi-Fi calling enabled you can use it to make calls, and to receive calls when the phone is unlocked or plugged in. Further, if you receive a cellular call while the phone is locked, and you then unlock the phone (to turn on Wi-Fi) the call should automatically switch to Wi-Fi calling; you should not have to turn off cellular.

One setting to check: Go to Settings/Cellular and scroll to the bottom. Make sure Wi-Fi Assist is off.

Can you explain why it's good to turn Wi-Fi Assist off?

I don't know whether or not it switches to Wi-Fi for data, I'm 99% sure it doesn't for phone calls. As I said the caller calls back after I switch off cellular and the call quality is good. Is there a way to know how one is connected when on a call?

I did just turn off Wi-Fi Assist. Hopefully that will do it. How would one know that this setting is important?

Thank you.

For me, it’s because of the limited data plan we have with our cellular data provider.

‘and have found on occasion where it would switch over to cellular when we would shut down the internet router at night or when WiFi ‘thought’ it wasn’t working and switched over to cellular.

If you shut down your router at night (which is unnecessary except to save a few watt-hours of electricity) you should also turn off cellular data on your iPhone: Settings/Cellular (Settings/Mobile Data) outside of English-speaking countries.

Wi-Fi assist switches to cellular data when the Wi-Fi signal is weak.
