Not returning to 4G after call

Anonymous
Not applicable

Hi all

 

The area where I live doesn't have VoLTE/4G Calling, so when I make a call my iPhone X switches to 3G. 

 

The problem is that it does not return to 4G after the call, no matter how long I leave it. The only way to return to 4G is to toggle Airplane mode or power off/on. 

 

All settings seem to be appropriate and the same phone (and settings) worked fine on Vodafone on EE. 

 

An O2 Guru told me that I didn't have the correct bolt-ons and claimed to fix that but I can't see that being the issue as my phone does connect to 4G, it just doesn't return to 4G after a call. In any case, the changes did not have the desired effect.

 

He has also arranged to send me a new sim however I'm seriously doubtful this will resolve the issue either. 

 

Does anybody have any ideas?

 

Thanks

Dave

I seem to recall this been asked before on here and that was an iPX too.
A new sim would be the first thing to try but I'm not aware that the issue was solved for the other customer who reported it either.

Seems a bit flaky at the moment. I disabled the option for the moment.

Might be worth disabling just the 4g calling part in phone settings on the iPhone rather than the entire 4g/wifi option.

My wife has a 6 with wifi calling enabled and doesn't have the problem as as the previous issue was also an X I guess it must be limited to that handset or a combination of handset and settings.
Have you tried with wifi and 4g calling disabled completely in your MyO2 ?

I have just requested to remove WiFi calling and 4G calling and will see what happens once the request has been processed.

I have a 7 Plus & If I have something like this then I switch off mobile data, leave it a few minutes then put it back on. Solves the problem every time

I've now tested this and it had no effect. I have added 4G and WiFi calling again.
