iOS 18.0 update causing SOS Mode

Not a Verizon issue. Everyone in my family who updated to 18 is stuck in SOS. My two sons sis not update to 18 and they are not have this issue. Their phones are working fine.

This is my exact problem right now my phone just all the sudden today decided to be on SOS this is days after the iPhone update 18. As well as everything lags and is slow. How is Apple fixing this? Like this is an OK I have a daughter with epilepsy that has to be able to communicate with me and if I go away from my office, I’m not able to use my phone without Internet. This update is clearly a dumpster fire.

Is Verizon your carrier? There is a widespread outage right now which could be the cause of “SOS”

I updated this weekend and am now stuck in SOS mode. I have restarted my phone twice and turned cellular on and off.

If you see SOS, No Service, or Searching on your iPhone or iPad - Apple Support

I am having the same problem after upgrading to 18.0 last night. I’m stuck in SOS mode. I’ve reset my network and still having the same issue. No one is having this issue in my household but me. We are all thru Verizon. Help!

FWIW my iPhone is stuck in SOS mode and I DID NOT do the software update (running iOS 17.7). Per some news sites and folks online, there appears to be some strange outage randomly impacting users across the US.

I had the same issue and I am not a Verizon user. I ended up turning my phone off for about 60 seconds and then turned it back on. At first it showed up in SOS mode and about a minute later it searched for the network and I'm no longer in SOS mode. Hope this helps.

I got service back yesterday evening, at which point I assumed Verizon had fixed the issue. This morning I’m back in SOS mode. I updated to iOS 18 yesterday. My husband did not, and he does have service now. Scientific method here is telling me it’s not a Verizon issue at this point. Anyone have a fix on the Apple end?

I am also having the same issue

I updated my phone to iOS 18 and my phone has been kicking back and forth to SOS for 2 days. I’ve followed all the instructions from the iOS support link and nothing has worked. I have Verizon too and so does my husband. His phone is fine. He has an android phone.

Update: Saw the news article below about widespread outages; thanks.

I am waiting for a Verizon rep on chat, but my iPhone 16 is stuck on SOS mode, but my wife's iPhone 15 is working fine. Both have been on iOS 18 all weekend working fine. We are in Washington State, far away from the hurricane impact area (which BTW, deserves every priority in getting their service back).

My Verizon Chat window has this message: "We are aware of an issue impacting service for some customers. Our engineers are engaged and we are working quickly to identify and solve the issue." I can't imagine why one version of iPhone would work and another doesn't in connecting to the Verizon network.

Verizon has acknowledged that there is an issue on their end. My wife and I both were on iOS 17.6.1. I have the issue and she does not. I upgraded to 17.7 just in case, but it did not resolve the issue. We do have different devices, so that could be part of it, but it's not iOS version specific.

same problem. I updated last night and its been in SOS mode since. I’ve tried everything (airplane mode, restarting, checking carrier services, diagnostics) and nothing is working.
