No Service after iOS 17.0.3 Update

I also have the same problem. I think it happens to some people globally.

Device: iPhone 12 pro max

Country: Indonesia

How do we fix this? It’s stuck on SOS and nothing is working. Is Apple working on this issue? Pro max 13

Having same issue with iPhone 13. After 17.0.3 update

After updating 17.0.3 there is network issue error on mobile service

any update from Apple?

there is no detail about carrier update in mine

means that my carrier is updated

i still think its a bug in iOS 17.0.3

Is it an eSim supporting a quick transfer, an eSim where you should call your carrier to activate or a physical Sim?

Me too!! Indiana, 15 plus. I updated to the new iOS a couple days ago and out of no where about an hour and a half ago my phone has been stuck on SOS, SOS Only, and No Service! I’ve also tried resetting the phone, and network settings but nothing is working. There’s also no outages for my carrier either. So aggravating ):

Also, I should add that it seems to be ignoring the proximity sensor ever since the update also…I’ve made so many pocket dials in the last week and Siri keeps activating over and over while in my pocket

I’m experiencing the same thing. I use to have full service all the time and now I have 1 bar most times and my phone is inoperable unless I’m on wi-fi. Prior to the update I had 0 issues with cellular service.

Exactly, unnecessary stress… I don’t mind social media at all but I need maps and other apps to go to the forest, hiking, etc… Imagine if you working with internet and stuff?

This iOS also drains my battery and my phone shuts down during the evening out of nowhere. I mean, if the next iOS doesn’t fix these issues I’m getting another phone, no more iPhone, I’m already that upset by these iOS errors…

Could just be my overactive imagination but the whole situation seems incredibly sketchy. How could an iOS update either,

A.) Glitch the phone out to detect critical water damage.

B.) Make preexisting water damage destroy the phone.

C.) only glitch some phones to completely break to where Apple must give you an entire new phone.

None of those really make sense, and it makes me thing that Apple put out a bad update, possibly to generate revenue, and is trying to cover their tracks by claiming the phone is water damaged. Again I’ve never even submerged the phone in water. If it was truly water damage, then these phones need to be reinspected for their water resistance because I did nothing outside of the parameters of their advertised water resistance. That or they just boldfaced lied to me. Genuinely been debating about switching phones because of this. No real explanation, no real cause other than a faulty update. The phone I have now is running on iOS 17.0.3 completely smoothly, so it really doesn’t make any sense unless it was manipulation on Apple’s part.

iOS updates have rendered my 13 pro max useless for calls or texts. SOS will only show for service. Error message also saying no SIM card. Thwarted at every turn when I try all of the recommended fixes. Tried connecting to iTunes on home computer, but that doesn’t work because of phone saying no SIM card, so home computer doesn’t recognize device.

Another data point...

On an iPhone 14 (I believe), it seemed to possibly be having similar issues however the phone had not yet updated to 17. I don't have direct access to the phone at the moment so some of this is from memory but...

As I recall, the About on the phone had one of the newer 16 iOS updates and not 17.

Maybe there was something from 17 backported to the 16 line or a similar change made in both versions causing the problem. Maybe that could isolate things some.
