“No Service” after iOS 13.5.1 iPhone update

My mother has the exact same Problem and i tried everything resetting network settings phone etc exchanged sim cards and nothing worked she has the Problem since the new update on her iphone 6s.

This needs to be fixed with a new update😠asap as ive seen now people have this problem since 3 weeks and theres no fix how can that be Apple ? Serioussly?? Listen to your customers pls

Update 13.5.1 sucks!!! Loose service all the time even where I use to have all the time. Even went as far as having carrier issue me a new phone. Same problem with new phone, it’s very frustrating Apple needs to address this ASAP... If anyone has suggestions please let me know

I’m having the same issues on US with Sky Mobile SIM .... in Iphone 11..... no service after update of 13.5.1...... new SIM didn’t rectify it... restoring network settings don’t resolve.... spent hours with Apple on diagnostics..... totally believe a fix needs to be issued!

That's a bold claim that I'd be willing to wager you're unable to prove. Correlation does not equal causation and in general, software updates/enhancements do NOT cause hardware failure. At the end of the day, you're certainly entitled to believe but if you're going to be making claims like this publicly, you really should have something to back it up besides your feelings.

I have the same problem with my iPhone XR. This is complete BS. My phone worked before the update and immediately after the update it says cellular update failed and Apple decides to blame us as customers. I think we need to come together and do something about this.

It is deffenetly the update if i take the sim out into another device it works and if i take another working sim into the iphone the sim doesnt work and thats exactly since the uptade 13.5.1 installed and it worked perfect before no fix not with network reset nor complete reset

It's hardly a bold claim given apple's reputation for not addressing their mistakes until a critical mass of complaints is reached. I didn't say that I lost my car keys and now my phone doesn't work; that would be an example correlation doesn't equal causation, my phone was working a midnight, it did an update, then my phone wasn't working. I have not claimed that my phone had a hardware failure, in fact I am glad that pointed out that software doesn't cause hardware failure.

Of course I can't prove it, apple doesn't offer that kind of diagnostics and doesn't actually do board repair. I have to do my own research, reading apple developer forums to see what problems they are working on.

thank you for the scolding it was very helpful coming from a level 7.

It’s happened not only in US but also in some other countries. I am from Bangladesh and having the same issue with my iphone here. I know a couple of more people who are also having issues with their iphone, even with their ipads after this 13.5.1 (crap) update :/

This is July 12th. Same problem of "No carrier" with an iPhone 5 after installing iOS 13.5.1. I did the "Reset Network Settings". Then I shut down the phone. Now the phone is back to normal. Thanks for all the people who helped with suggestions on this thread 😃

I find that my iPhone 7 still restarts by itself and sometimes comes back with “no service”. What I have found is that doing a soft reset fixes it nine times out of 10. (hold “volume down” and “power” together until iPhone 7 switches off and Apple logo reappears).

I took my iPhone 11 to the Apple store a couple of weeks ago for this issue. Despite several factory resets the problem remains. They offered to send the phone in but I've decided to wait until the next update to see if that fixes the problem.

FWIW, I've found that a number of power cycles will usually get it working right eventually (for both my physical VZW SIM and ATT eSIM) and that will usually last a couple of days before one of them drops to No Service.

I wish they hadn't un-signed the earlier iOS so that I could just roll it back...

I had that problem, and as someone had said before, there was a problem in some Iphone 7 models, so I took mine to an Apple Store and got a new phone, and so far everything is working well... Hoppefully will just continues like that.

Had to use “Lost mode” in find my iPhone on Sunday after loosing my iPhone X whilst MTBing. Someone found it and rang us, got the phone back quite quickly but then shortly later I had the dreaded “No service” again. I had this issue approx 4 weeks ago straight after the 13.5.1 update. Only backing up then restoring got it working again, I had to do this again yesterday to get the cellular service back!

Come on Apple!!

What is the issue here and why have you still not sent out an update to fix this problem that so many of us around the world are experiencing since the 13.5.1 update. It’s not just iPhone 7 users. If this happens once more I’m off to buy an android phone. It takes approx 6 hours for my phone to back up and do a restore and then put the back up back into the phone. Time I do not have spare!!!

update from above...

The back up/restore has not worked. I still have "No Service" (cellular), although I do have Wifi Calling on my UK carrier EE showing, which is better than yesterday when i had neither. (to clarify this is on iphone X 256gb)

I will phone Apple again this morning and report back.......

ok my iphone X has miraculously started working again.... I now have cellualar service back. What seems to fix it for me is taking the SIM out and leaving the phone for a few hours. I did this to get my old iphone 6 up and running again so that I had a working phone (with the same SIM). Then some hours later.... I try the same SIM back in my X and it seems to rectify the "No Service" issue. very strange. Spent approx 2 hours on the phone to Apple this morning and got absolutely no ware! Passed from person to person.

Just had an email from Apple promoting the iOS 14 !!! Not sure when it's coming out and not sure I want to risk it again after the trouble 13.5.1 has caused me and so many others around the world! Or is this the update fix as well?
