IOS 17.3.1 issue SOS only

There is no outage it seems woke up with SOS in the morning today

iphone 15 pro upgrade to ios 17.3.1

N/w ATT

State-WI

reset network -2 times

tried toggling airplane mode 100 times

tried restart 5 times

tried shutdown and switch back on 5 times

still same SOS message.

Same. My phone was working fine yesterday before I updated. If I knew this would happen, I wouldn't have updated my iPhone 12. I've restarted my phone a couple of times and it still doesn't work. I don't know the source of the problem, but Apple at least needs to announce something regarding this issue.

Upgrade to 17.3.1 immediately set my phone to sos. Have consumer cellular. Other phones without upgrade still working.

Don't restart your phones that are currently working as you may have the same problem with those phones as well. The problem is with establishing a cellular connection which happens after a restart, such as when your software is updated.

My husband stayed with 17.2.1 and is not having any issues today. Has anyone else noticed this?

This issue has nothing to do with the update, or the model or brand of phone you have. It's an AT&T network issue.

I have two iPhones, one personal and one for work. Different models but both AT&T. This morning, both had service as normal. After updating my personal phone, it's now in SOS. My other phone that I did not update has service and is working as normal.

My wife and I are both on AT&T. I updated, she did not. She has cellular service and I don’t. Seems like an iOS issue and not an AT&T issue.

Have you verified that by restarting the phone that did not update? It appears to be a connection issue that is affecting phones after they are restarted, such as when any update has been performed. I don't recommend restarting the phone, because I believe you will lose service with that phone as well, but I wouldn't claim it is an iOS issue since it is happening to people who have not updated after a restart and on Samsung phones as well.

Me. I have two iPhones, one personal and one for work. Different models but both AT&T. This morning, both had service as normal. After updating my personal phone, it's now in SOS. I did not update my other phone and it has service, working as normal.

My wife hasn’t restarted her phone and I’ll instruct her not to. However, my sister updated last night and hers is working fine. She’s also on AT&T. Weird. It seems random.

The fact that it's not affecting everyone is adding to the confusion, certainly.

Update: There is no outage where I am. I don’t have time for this crap today, so I just reset my phone and restored it from an iCloud backup from before the update and got a new eSIM card from ATT. Phone is still on SOS only.

Claiming that there is no outage in your area is irrelevant. Even if you call your neighbor, that call is routed all across the country where there are network outages.

I thought about calling AT&T for help, but I realized I don't have any signal so there's no way I can call them lol. I tried to log into their website and see if I can get online assistance, but AT&T website was trying to text me a verification code to login. Ironically, I coudn't receive any text because I'm out of service. Now I'm completely stucked....

I went through all of the steps listed within this thread with no joy, the SOS is still listed and unable to make a phone call. Wi-Fi is working correctly and I am able to send text messages via messenger. I did receive a comment that suggested there was an issue with my iphone, however couldn’t identify issue. As I cannot talk to a person, nor sign into my account with my carrier of stuck no luck there. Other iPhone on same plane without update are not having the same problem. Guess it’s not the end of the world time to go vote good luck keep me posted. I will stop by Best Buy and if I have resolution I shall post. Have a great day.

I am having the same issue. Updated last night and now iPhone is stuck in SIS. Tried restarting phone and router, then rest network settings. Nothing worked. Help.

I'm having the same issue as well. My phone updated last night and I'm stuck on SOS Only.

Could be but 3 phones on the same Att plan, only 1 updated and that one has no cell service now. Goes between SOS and no service.
