Wi-Fi calling not reconnecting after returning home

[Kuribo]

So on an iPhone 13 on iOS 16.6.1 (this happened on 16.6 and previous also), I have Wi-Fi calling enabled but if I leave the house and return it doesn't reconnect when I'm back on the Wi-Fi unless I turn on and off airplane mode then it will kick in and stay until the next time I leave the house. I've tried hard reset and also reset network settings but not effect. Wondering if anyone has any suggestions? Just irritating having to remember to do this to get it back every time I have to go out. As I say if I remember to toggle the airplane mode it will come on and works just fine… until I go out. I’ve also asked this in the Apple Help section of Reddit but no replies as of yet. Thanks in advance!

Does your wifi reconnect or not?

Is it just wifi calling that doesn't engage?

Hi, yes Wi-Fi always reconnects perfectly fine, just Wi-Fi calling will not come on until I turn on airplane mode and turn it off again - so it connect to Wi-Fi but stays saying normal “O2-UK”, then I turn on airplane mode (but leaving Wi-Fi on) and then it will come up “O2 WiFiCall” then I can turn airplane mode off and the Wi-Fi calling will stay on (until of course I leave home).

Not come across that issue before @Kuribo 

Have you asked O2 to check your account?

I haven’t but it’s definitely enabled, I’ve used it since it first rolled out as I’ve always had it on phones and used to live in a basement flat with appalling signal, as I say it is enabled as it connects and works perfectly fine as long as I do the airplane mode, I’m hopeful perhaps iOS 17 may fix it for me when released in the coming weeks. Although it could be a Virgin issue as I’m with them also and have one of their (notoriously rubbish) “superhub” routers. I need to connect to a different Wi-Fi to see if it will kick in of its own accord then, that way I can tell if it’s a Virgin problem at home or not. Thanks for replying

Just an update to say I have managed to solve this with a SIM swap, asked in store and since using the new SIM it’s working fine as intended and auto switching on Wi-Fi calling when I’m on Wi-Fi.

@Kuribo Good to know.

Update on update - since updating last night to ios17… it’s back to the old behaviour of not coming on - so I’m having to toggle airplane mode again to get it to activate 🤦‍♂️.

I’ve tried everything again - reset network settings, hard reboot, even ejected the SIM then put it back. Curiously when ejecting the SIM and reinserting it did activate the WiFi calling on its own but now it’s back to anytime WiFi is off or out of range and you reconnect - nope. I can’t keep swapping my SIM every time there’s an update. At wits end it’s so frustrating!
