iOS 16.3.1 now only in SOS mode..

I am having the same issue with SOS coming on after the update and I am within range and do not need it on. I have attempted to turn on airplane mode, turn it off, turn off my phone and turn it back on- still doesn’t work. I went into my settings, it’s like it’s not reading my SIM card. I have gone to settings>cellular>SIMs and my “personal line” is off. I have tried to toggle it back on but it won’t stay on. It’s like my SIM card isn’t recognized.

Has anyone else experienced this and if so, how did you correct it?

If you see No Service or Searching in the status bar on your iPhone or iPad (Wi-Fi + Cellular), your device isn't connected to a cellular network. If you see SOS or "SOS only" in the status bar, your device can still make emergency calls.

Turn airplane mode on then turn it off and it fixed mine.

FYI, I had the same problem after updating my iPhone 13 Mini to iOS 16.3.1. I fixed the issue by going to Settings->Cellular. Under the SIMs section, make sure your "Primary" line is On. For some reason, after updating, the "Use as Cellular Data" line was On, which prevented me from turning on my Primary line.

In summary, my fix was:

1) Make sure "Used as Cellular Data" is Off

2) Turn On "Primary"

I double checked this gave my phone and data again on my phone. Hope that helps!

This is not a helpful answer--I don't want it to be in SOS mode. This didn't happen before update.

@ SravanKrA, I think you have misunderstood. The SOS mode is a result of the update to 16.3.1.

You misunderstand. The cause is irrelevant. The solution is to find out why your phone isn’t connecting to your carrier’s network. And amiebc has posted one possible solution.

Thank you for the feedback. Not sure what I did but eventually, I was able to get my personal line to turn back on. Great advice. Thanks again!
