This is so odd. I have two phones with AT&T currently sitting right next to each other. One has service, the other is in SOS mode.

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.

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

Different bands could be affected differently if it is solar radiation related. Same exact model of phone?

Same year, different size (13 and 13 Pro Plus)

Does it still show bars in SOS mode? Or is SOS just “I dunno can’t see no cell towers but maybe it’d work?” I wonder if the MVNOs that piggyback on AT&T are showing down also. If not, it’s some AT&T service authorization system that exploded.

SOS mode means it can see towers of other providers you aren’t authenticated with, but no signal to authenticated cell towers

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'll take a chance here and say this was a hack, possibly at the equipment-level. One major carrier having an outage? Possible. But three? On different networks? Even if its not a hack I'd love to see the root cause on this one! Communications is critical infrastructure, so I'm gonna guess the government will demand a full report.

There is some shared infrastructure in the PSTN that all network operators use. This smells more like an SS7 outage to me than a hack, but we'll have to wait to find out.

Backhoe fade?

Back in my circuit switched days, we lost half of our US long distance routes, because a farmer in Wyoming dig up an unmarked fiber link. Hence, backhoe fade.

Sounds like it's really only AT&T. Most likely somebody screwed up a configuration change and took out a lot of capacity.

My brother sitting next to me with an AT&T Pixel 7 has no service. Me with a Pixel 7 Pro (dev preview android) on the same plan: not affected. Strange.

i was showing none with iphone 14, wife had like 2 bars with her iphone 11. i wonder if its just part of the newer infrastructure.
