Stop auto switching from wifi-calling to mobile data

Is it possible to stop iPhone automatically switching from wifi-calling to mobile data?


I live in a remote area with terrible reception, so wifi-calling is extremely useful. When just calling through wifi-calling I have no issues. However, occasionally, I get one bar of mobile data mid call and my iPhone seems to automatically switch mid call to that, which then reduces the call quality dramatically - often resulting in me having to end the call and try again via FaceTime audio or WhatsApp!

iPhone 13 Pro, iOS 15

Hi _al2478,



Welcome to Apple Support Communities.


Have you tried turning off cellular data after you have received the call? Some carriers may require cellular data to be on as mentioned in Make a call with Wi-Fi Calling.


To turn off cellular data easily, use Control Center: "On an iPhone with Face ID: Swipe down from the top-right edge. To close Control Center, swipe up from the bottom."

Use and customize Control Center on iPhone




We hope this helps.


Cheers!
