Some of our staff are reporting similar where their partner's phone has service and their's doesn't. Both on same AT&T family plan.

So the radio bands may play into it although I would think with latest iPhones, they can use any of the bands from AT&T although I could be wrong.

Can you check if things improve if you turn off 5G and move to 4G/LTE instead?

[nathanyz]

Good thought, but switching to LTE only didn't work. Same result of ending up in SOS only. Cellular over wifi works perfectly fine though. Wish we could count on better post mortems from the phone companies, but I'm not holding my breath for it.

I'm wondering if it could be some kind of auth timeout. I've heard from a few people of one person's phone going out, then a bit later the other person's phone finally failing too.

I'm on the latest iPhone and it's SOS for me

Yep: my partner's iPhone has service while my Pixel doesn't, both on same plan.
