So my iPhone 15 pro max works beautifully now, after two months of absolute headache. I’m in the UK not the US but I’m hoping this will be the same fix regardless. My data was constantly loosing service and would not reconnect automatically, I had to use airplane mode on/off to reconnect.
i spent the whole of January speaking with my provider (o2) and after trying new SIM cards and them sending my phone the correct settings, and ‘apparently’ having had an engineer look into my issues I was told it now looks like it’s the phone itself, my newly bought 15PM.
There starts my numerous trips to Apple, firstly after an in-house text they changed the main module on my phone. I’m not too technically minded but was told it’s basically going to make it a new phone.
This did not work.
Then, after showing the Apple staff how, after being connected to their store WiFi and then walking out of the store I had no service, they gave me a completely new device.
Still the same issue.
I then bought an iPhone 14PM from Amazon thinking that the old device would be fine. No luck, that went back.
At the end of my tether now I bought an eSIM which was with another provider EE. This worked faultlessly.
so I had my answer, it was NOT the phone after all, it was my provider, o2 all along.
i called o2 and told them I was leaving as they were not providing a ‘fit for use’ service.
after speaking with various managers I was all set to leave and then, out of the blue received a text from o2 engineer dept telling me the problem had been fixed and to restart my phone for it now to be working properly.
i was just about to terminate my contract having been with o2 since 1998 (originally BT cellnet) so I did this last attempt, and it worked.
after what seemed to be so long and with me trying all possible routes it turned out to be a provider connection issue.
i am in the process of discussing compensation with my provider seeing as it was their fault all along.
Apple were great all along my journey and could see my fustration.
i did take out Apple+ care and they were willing to take the phone back for a full refund if things didn’t work themselves out. I cannot fault their service.
i hope this may help if you have the same data not automatically reconnecting itself issues.
