“No Service” after iOS 13.5.1 iPhone update

"PS Pause" this method you suggest below isn't working for me. :-(

"Steps I take are:

— Flight mode

— Turn off iPhone 7

— Turn on iPhone 7

— turn flight mode off.

if that fails, try turning Location off.

then repeat above. "

I spoke to Apple Support and they helped me. I also had the issue of No Sim or Service and No Carrier after update. They helped me get my Phone working by going to:

Settings > General > Reset > Reset Network Settings

I did that and Boom. I’m able to write this message on my phone on my regular cellular service. Let me

know if this works for you.

It could be a temporary fix in my experience. I’ve had this problem since late last year ever since updating my iPhone 7 from iOS 12 to 13. It would periodically crash and restart, sometimes giving service and sometime “no service”. But iOS 13.5.1 just killed it dead as a phone until I did the whole “erase/restore” fix. Now it’s back to crashing periodically.

Yes I can confirm it's Apple's 13.5.1 update that is causing all the problems.. i have now got my old iphone 6 back up and running and it works fine with same SIM card and same network (EE UK). My iphone X still has no cellular network connection.

I only hope Apple is actually working on this. I spoke to a client in Hong Kong earlier, he has exactly the same issue after updating to 13.5.1 He was about to go to another cellular network thinking it was his existing network that was causing the issue.

Hurry up Apple. Seriously not impressed!!!

Those 2 posts contain links. A link is a way to open a page with additional information; it is shown in blue text on most browsers. You click on the blue text and a new page will open, in this case a notice that some iPhone 7’s have a problem that Apple will fix out of warranty, and how to get your phone fixed.

Yes i understand that. You miss interpret my message. I was confirming that it's the not just an iphone 7 issue as I'm on an iphone X, and others I've spoken to are also having this issue with the 13.5.1 update that aren't on iphone 7. I have been commenting on this for a few days so it's a rolling conversation and not always a direct reply to the message above ;-)

The subject of this thread is iOS 13.5.1 update created "No Service" on my 7 iphone. [emphasis added]

If you have a problem that is not related to the subject of the thread you should create a new post for the problem, rather than “threadjacking”.

apologies....

somehow I seem to be in a different thread to the one about the 13.5.1 update issue which is also causing a NO SERVICE message and failure to connect to the cellular service provider.

It can happen. No worries. iPhone 7 has had this issue for years, and any connectivity problems on other models most likely have a different cause than the problem in iPhone 7’s.

One thing to check is your carrier. For example, early this week T-Mobile had a 12 hour nationwide outage, and it didn’t completely fix it for several days. And just checking, it’s down again now over most of the Eastern US. Yesterday Verizon had an outage that covered much of the US (much of the East Coast is still down), and, unrelated, Vodaphone in the UK had an outage centered on London and Manchester, but also other spots in the UK. Today there are scattered outages reported by AT&T customers.

I posted this earlier, but if you have a connectivity problem first check with your carrier and/or this site—>Down Detector - outages. Look at the maps for T-Mobile, Verizon and AT&T.

While it may be a problem with iPhones, with a lot of carriers showing problems it’s hard to tell.

For me it’s not just a phone suddenly showing “no service”!

It crashes, shuts down and then comes back either with or without service.

Intermittent service failure is one thing. An unreliable iPhone is another.

I had exactly the same issue, spent 8 hours on phone to tech people and also a visit to a Genius Bar. I now have a phone that doesn’t work as they tried to reset it in various different ways. And as it’s 2. Months out of warranty say my only option is to buy a new phone. 😡. Absolutely fuming. Was wondering if I was the only person, obviously not.

I’m having the exact same problem too, I contacted Apple and they said it was my carriers problem not apples and then I contacted my carrier who told me nothing was wrong on their end so it must be an Apple problem. Then I took it to my local Source store and they told me it was a software issue and after weeks I still have no service! I live no where near an Apple store. So now I guess I just pay for a phone I can’t use in hopes it’s somehow gong to get fixed ( update I’ve had this iPhone 11 Pro for only a week!)

Definitely a software issue. The workaround I am using, which is horribly inconvenient, until Apple actually get this fixed is to power off and power back on. Sometimes it works sometimes it doesn’t. When it does work I will have a signal anywhere from 10 minutes to 23 hours (the most so far).

Please, Apple!!

I've also shipped off my iPhone 7 - it was one of the models listed in the recall that others have shared. Hopefully that will solve the problem. My only concern is that people on this board with newer models are having the same issue, so it is possible it could still happen with the "fixed" phone

Yes, there is more than one cause of this symptom. For some iPhone 7 models there is a dormant hardware problem that an update (any update, not just 13.5.1) can trigger. For any other model with the problem there are basic troubleshooting steps that can fix it. This problem can occur at any time on any phone; it is probably coincidence that it happened after an update.
