“No Service” after iOS 13.5.1 iPhone update

The same thing happened with my 8 plus. I finally got in touch with a real Apple expert. After running remote testing, one test came back as a failure which was Presence Test Baseband. I have no idea what that means, but my expert did. Instead of dismissing me like everyone else as being unwilling to accept a hardware problem, she took me at my word that it was software related. After being told not to do a full erase/restore by the other Apple techs because it might make things worse, this one said to do it. I erased everything back to brand new, but did not restore it from icloud immediately because that could have brought back the bad update. We verified that the phone was working without restoring anything. Then we did a second full restore from the icloud backup and this time the update installed correctly.

Steps taken:

1. Back-up phone to icloud or computer.
2. Erase without restore, verify that phone and texting works. Your mobile provider should now show in upper left corner.
3. Erase again but this time restore from icloud to get back your contacts, apps, etc.

I hope this works for everyone else. They all told me it was a hardware issue and I would have to pay to have it fixed or buy a new phone. They were wrong.

I have managed to get it back working as a telephone!

I did the following steps:

• Back-up phone to computer.
• Erase without restore
• Warnings that it wouldn’t restore the iPhone because it needed an update.
• Sure enough when the iPhone came back to life, it would not restore.

Put your device in recovery mode and set it up again

• On a Mac with macOS Mojave 10.14 or earlier, open iTunes. If iTunes is already open, close it, then open it again.
• iPhone 7 : Press and hold the Side and Volume Down buttons AT THE SAME TIME. Keep holding them until you see the recovery mode screen.
• Told me it was going to recover the iPhone.
• iPhone 7 came back to life and Vodafone appeared!!
• With it connected to iTunes it did a Restore as above.
• It took about an hour to restore. And even longer to download all my apps.

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.

I have an iphone 7 as well and nothing in this thread has worked. My phone will work for a bit then it goes "no service". I stopped in at Verizon to see what they could to and I was informed that about two to three years ago there was a recall on some models of the iPhone7 for this exact reason. As it turns out, my phone IS one of these models so I'm mailing it in and hopefully their (free) repair will fix the problem.

Here's an article on that issue and the related model numbers. https://support.apple.com/iphone-7-no-service

Replacing the SIM in my iPhone 7 did *not* solve it for me.

That’s because it is a SYMPTOM, not a problem. There are at least a dozen different reasons this symptom can occur. For an iPhone 7 this is a good possibility—>iPhone 7 Repair Program for "No Service" Issues - Apple Support. For any iPhone here is a good place to start—>If you see No Service or Searching on your iPhone or iPad - Apple Support

I hope this was posted somewhere on those 8 pages but haven't noticed anything meaningful. It's just a coincidence, your phone has a faulty baseband that simply didn't pass the check during update. Apple fixes it for free: https://support.apple.com/iphone-7-no-service

Please see https://support.apple.com/en-us/HT201415. If these steps fail to resolve your problem and you have an iPhone 7, then see if you qualify for https://support.apple.com/iphone-7-no-service. If not, then you should attempt to restore your iPhone to factory settings and set it up as new. If you don't qualify for the iPhone 7 program and your device is out of warranty, then it's time to consider purchasing a new phone because a no service issue is not something that Apple would offer to repair.

That sounds like a hardware problem. Have you seen this—>iPhone 7 Repair Program for "No Service" Issues - Apple Support

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 😃

The Reset Network Settings alone worked -- did NOT remove sim card. But it wipes out the Wifi connections -- so make sure you have the passwords for reconnecting to wifi FIRST before you do!

OK Got there Connected to iTunes through the Macbook

4-Please follow the steps below:

1. Connect your iPhone to your computer
2. Open iTunes on your Mac
3. While your device is connected, force restart your iPhone. Here is how you can do that:
   1. If your device is an iPhone 8 or later: Press and release the volume up and then volume down button and then press and hold the side (on/off) button until you see the recovery screen below. Do not release the buttons until you see the recovery mode screen.
   2. If your device is an iPhone 7 or iPhone 7 Plus: Press and hold the side and volume down buttons together until you see the recovery screen. Do not release the buttons until you see the recovery mode screen.
   3. If your device is an iPhone 6 or earlier: Press and hold the side and the Home buttons together until the recovery screen below appears. Do not release the buttons until you see the recovery mode screen.

Did the restore a second time then set it up from the back up it did earlier, just before it installed 13.5.1 update.

This time it worked, phone is back up and running as it should be with all data photos etc and is showing it's on 13.5.1 can now make and receive calls again.

Changing providers won’t do anything. I’m with Vodafone in New Zealand and had the Same problem. Did a backup and restore, the device obviously wanted to update to 13.5.1 in the process but this time it works fine. Same provider same sim card.

My husband said the same thing, LOL. My phone is now working, but because if T-Mobile having outages throughout US, I can’t Rec’v calls from home to my cell but I can from my husband’s cell.

I had 0 cell ability earlier today. Tonight I had to backup my phone, Erase it, then restore it.

As this is a long thread, I did not get a chance to read through all of it.

However, a friend of mine has the same problem and when I tried putting in my own Sim (from different provider) on his phone it seem to work, although, his SIM, doesn’t.

This drove me to think, maybe the problem lay in the version of the Sim itself

I told him to try and talk with his provider and see if he can get a newer Sim and try in his phone
