Cellular service quit - 4 white dots in top right corner...?

Thanks! I tried that and it seems to have only deleted my saved WiFi passwords. It’s the cellular service that won’t work

I have seen this problem a couple of times. I have had to separate the layers and reball the interposer board. It is too early to tell if this is a permanent fix.

That's very good to know, especially considering I use an Xs as a personal device. In that case, I might recommend taking it to apple and replacing it before the warranty runs out to avoid further issues.
