I was doing research on this and years ago the iPhone 7 had a similar issue which resulted in a repair required by Apple. Why have they not started this yet? I really think they’re trying to have as many people buy new phones...IF I buy a new phone- I’m going back to android. There are other fish in the sea.

Going on...4 months for me. For my birthday- I am getting an android.

So heres what I noticed after 10 months of dealing with this issue- IF there is a wifi present- the phone automatically switches to wifi, normal occurrence. THEN I lose all cellular data. I RARELY see that both exist. So for the last week- I reset my network settings and am solely using cellular, it went out ONCE for 3 seconds and came back. Fix this APPLE!
