No Service after iOS 17.0.3 Update

i got a notification to update my iPhone 14 promax to iOS 17.03 which I did. After the update, my device has been displaying no service. I have done all the recommended solutions on google ( removed and reinserted the sim, reset settings, hard restart, no iOS update). Is there any other option to explore?

Same exact issue happened to me. iPhone 13 Pro, the download automatically went through last night and so far I have been completely unable to connect to my data. Been having to use my school’s WiFi for everything but cannot text or call without it. Hoping it’s just a glitch, any solutions?

I had the same issue a few days ago and it resolved itself. Next morning I had the same issue except nothing would resolve it. Reseated the sim twice, reset network settings, did a soft and hard restart numerous times…it eventually came back about 8 hours later after about my 100th time putting it in and out of airplane mode. Hopefully they fix the bug soon.

My two daughters also had this same issue with their phones although oddly enough my husband or I had this problem at all. I did all the research you all had done and it got nowhere. Finally, I took it upon myself to try doing it on my own, and BAM! It worked. This is what I did to both iPhones that were running iOS 17.0.3. Let me know if it works for you as well.

  1. I put the phone in airplane mode
  2. connected to wifi but keep in airplane mode
  3. Settings- General - Software Update (you should now see a new update.. I had 17.1.1)
  4. KEEP the phone in airplane mode and connected to wifi until update is complete.


THAT IS IT!!! LET ME KNOW IF IT WORKS FOR YOU!!

So here’s the strange part. I took it to an Apple Store and they said it was in fact a hardware issue, specifically water damage. They essentially replaced the entire phone other than camera and one other component. The phone I have now has an entirely new serial number and everything. I fail to see how a software update could have essentially destroyed the phone to the point that it wouldn’t even read SIM cards though. I’ve dropped my phone in the shower once or twice before but never had any issue with SIM card reading or anything of that nature. It was also going to be a 530 dollar repair without apple care, so if you are going to visit a location I suggest paying the 10 bucks for apple care before you take it in, because I have to almost assume the update killed my phone beyond repair, and they covered their *** by claiming it was water damaged. Incredibly strange circumstance, and seeing so many people in this discussion almost proves it couldn’t have been preexisting water damage or something like that.

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.

Follow up to this...


I went to the ATT store in person, rather than get a new phone number, a new eSIM was created on the 15 Pro Max phone. It still did not work.


Transferred the eSIM to the old 12 Pro Max (which had been factory reset in preparation to trade in) and the internet on Cell Data appeared to work.


Transferred the eSIM back to the new 15 Pro Max and the internet on Cell Data did not work.


The assumption was, something no longer installed or configured on the factory reset phone cleared out the problem but when returning back to the 15 Pro Max (which was transferred previously) this transfer between devices may have brought the corruption with it.


It was suggested once again to work with the Apple folks for additional troubleshooting (with the possibility of maybe identifying possible app problems or other diagnostics on the 15 Pro Max.


Diagnostics on the new phone passed without any apparent problems (the previous diagnostics on the 12 Pro Max were not there on the new phone so at a minimum some of the previously diagnostic problems were no longer a problems - i.e., the battery and/or wireless recharging did not appear to have problems any more).


It was suggested to Factory reset the new phone


After factory reset (without any apps installed yet), the phone internet over Cell Data worked.


There is no way to "selectively restore" files so it was necessary to go to the App Store, select the profile, and Purchases apps, and reinstall apps of interested.


Start reloading apps (not based on a iCloud backup) to help isolate if there was a specific app which might have been causing the problem or the corruption.


I used this as an opportunity to reduce the apps on my phone and focus on the ones I use more commonly.


Because the "iCloud backup" was not used at the time, many of my customizations were lost (i.e., my apps in folders - having to reorganized apps [unable to do so on PC either as iTunes app management not possible that I could tell at the moment], my preferences, and some app data which while may have been backed up to iCloud where not able to be restored per an "iCloud Restore" or "app data stored in the cloud"). As one example, one of my password management apps was unable to be restored fully so I lost some of by passwords.

As of this moment the phone appears to still be working but was unable to identify a specific app that may have caused it.


Given some of this started when moving between locations, I'm curious if some sort of "roaming" activity could have in someway corrupted the SIMS, network, or connectivity and just got stuck that one. But I'm not sure.

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.

Update on my iPhone 12 Pro Max.


After almost 2 weeks with TOTAL no services (can't read SIM card), suddenly 2 days ago, my service appeared back for some minutes. And went back to no service again.


Yesterday, i got signal for several hours before it disappeared again. Tried restart and other things but didn't work.


Today, my signal has appeared since morning. I can send SMS dan phone call. I didn't do any update, just reinserted SIM card and on/off airplane mode.


If this **** bug not coming back again, I have no reason to immediately update iOS 17.1 when it's launched. I'm sure there will be another bug.


I suggest you guys disable auto update software. Better to wait 1/2 months after the latest updated released.

im not really sure what you mean by channel

but i was contacted by Apple Care team ****


At day 1, i tried everything: reinsert; on/off airplane mode; restart network settings; use another sim card; restart phone many times. Nothing worked.


For almost 2 weeks, i just reinsert SIM card and on/off everyday. Suddenly my iPhone was back to normal again, the network was back
