“No Service” after iOS 13.5.1 iPhone update

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...

Same problem. After trying several suggestions, with two of them working temporarily, I finally took the iPhone 7 to an Apple Service place, and got a loaner phone, while they send mine in for fixing. Took a while on hold to get an appointment, but can't complain now. 😃

As arranged with Apple support I went to the Apple store for my appointment today and they confirmed in store that my iPhone X was not receiving any cellular service. They replaced my 2 year old iphone X 256gb with a new one, like for like. Back home and after a few hours I have done a full restore with my previous back up and everything is working as it should. I can confirm it also updated to the latest 13.6 software.

I now have a fully functioning iphone X again with working cellular service.

Over 4 days in total of my life wasted that I'll never get back!

I think i cracked the code. So i took an old iphone 6 and put my sim card in it then ran my apple id through it. I swapped out the sim back and forth between my iphone 7 (which has been losing cellular and shutting down at will) each time it lost cellular with the iphone 6. About 3 times. I got messages from apple SUPPORT telling my id was used on s iphn6. Now Ive gone 3 days without losing service in the iphn7. It doesn’t make a lot of sense but all of a sudden the iphn7 is working perfectly. The 6 has a lower ios than the 7. Somehow something told my phn7 to stop its intermittent cujo behavior. I was going stop using the 7 altogether but the switching in and out seems to have confused it. Now it works. Hmmmmm. Who would have thought Its like big brother is confused. Who knows......the saga continues.

They keep saying it's a hardware issue and since our phones are out of warranty, we should pay to have it fixed. This was obviously caused by the software update. There are too many of us having the exact same problem. Unfortunately, while we wait for Apple to figure out what they did, we are without phone or text service! One person on several of these threads keeps insisting it is hardware. How can all of our phones have hardware issues at the same time after the same update? Our phones say no service too

It's a network issue, it's not happening to Vodafone clients here in the UK only to O2 and EE so I'm lead to believe. So it should make a difference. It's something to do with the network settings for the providers.

Has any UK Vodafone client had this issue? Please post up if you have.

Thanks

Ok you could be right on the Vodafone thing... just tried my wifes Vodafone SIM card and it made no difference. Strange how no Vodafone customers here in UK aren't having this issue. Well that's what the Apple senior tech agent told me!

Be interesting to hear from any UK Vodafone customers that are having this issue.

Seems to be centered on London & Manchester, with scattered other areas.

This worked for me... Thank you

After erasing the phone i could not connect and activate it though wifi or Macbook connection. I was stuck untill I put it to recovery mode. Once in recovery, connecting to the MacBook didnt help but I just restored it from iCloud through wifi.

Thanks again.. :-)

Hello,

I tried this and now my iphone cannot be activated. I was able to use apps from wifi however after trying this method, I can't even complete the activation. This may be related to my model of iPhone 7 - A1660 which qualifies for the no service repair program. But as it is past 4 years since the time of buying I cannot apply.

I was having this exact same issue on my iphone X straight after the 13.5.1 update which I did through my PC and iTunes. I spent 3 days in total messing around trying everything to get back the cellular service. I had to start using my old iphone 6 again (software version 12.4.4) with the same SIM and Cellular network and it was working fine. Then, a couple of days later I decided to put my SIM back into my iPhone X again and it was working!! and hasn't lost Cellular service since. Strange!

Same with mine, 8 hours on phone to Apple techs and a visit to Genius Bar. They’ve tried everything possible reset etc and phone is now dead. An Apple don’t want to know, won’t accept it was the software that started this. Told me to go to o2 and complain under the consumer credit law 2015. But to do this I have to prove the fault was on the phone within first 6 months of purchase - impossible.

Apple told us my husband's iphone7 model would NEVER work with the new update. Told us to send it in and they would send a refurbished model that would. Then claimed the phone was damaged other than the repair request and returned it. There is nothing wrong with the phone. The screen isn't even scratched. The only issue was the update. The letter also says if its sent in again they will charge a $100 diagnostic fee and the cost of repairs. WHAT REPAIR!!??

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!

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 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 :/
