"No Service" on my iPhone after iOS 14.7.1 update

"The program covers affected iPhone 7 devices for 4 years after the first retail sale of the unit."

"The program covers affected iPhone 7 devices for 4 years after the first retail sale of the unit."

Yes, if your phone is that old many things can go wrong with it. Nothing lasts forever.

Has anyone been able to solve the problem of no service?

I've updated my phone from iOS 15.0.1 to iOS 15.0.2 and facing the same issue

No luck

I don't think it's hardware, the exact same thing has happened to me on an iPhone XS. Working perfectly fine, run the update, no service. Have reset network settings, restored the phone, etc. nothing.

My SIM works fine in other peoples phones so its not a problem with the carrier. The error message my phone gave me specifically says the issue is related to a problem updating the software on the phone. https://support.apple.com/en-gb/HT208733

from that page: "If you see this alert, there was an issue updating the mobile communication features of your iPhone or iPad."

 "An update is required to use mobile data on this iPhone".  problem is it's the latest version of iOS thats causing this problem. That help article says to CMD + Click on the check for updates button to reinstall the latest version, however this doesn't appear to work anymore since CMD + Clicking that button just tells me I have the most up to date version still.

First of all, thank you for your reply. Here is what I've checked/done

1. Checked the SIM with another iPhone XS, working fine, able to talk, receive calls, using data etc.
2. Inserted others SIMs on my iPhone and I get "No Service" all the time.
3. Airplane mode was activated and deactivated.
4. Network reset was done.
5. Factory reset was done.
6. Updated to higher version of iOS update, no luck.

Since I live in Mongolia and there is no Apple service center, I think I'm finished with this phone. If I was in States or in Europe I could just visit to Apple service center. Also I know I can somehow contact to Apple and send this phone to them via DHL, but this is iPhone 7 we're talking about.

Did you update over the air or using a computer? Have you checked the modem firmware as I posted? If it’s an A1660 it is probably the hardware failure that the recall covers, but that probably won’t help where you are.

You probably have so many points because you don't read what people write and keep posting the same stuff over and over.

Yes there is a problem with my phone, I know that, because my phone doesn't work. I'm not even saying that the reason it's not getting service is software related, it could well be a hardware problem, I'm saying I believe its a hardware problem caused by a software update. If you don't think software can cause hardware problems then you don't know software.

I already read your troubleshooting advice, which by the way is bad advice. I checked the about section, and my modem firmware was indeed blank, so I followed those steps to restore the phone (exactly as you posted) which resulted in it being unable to activate. I've had it diagnosed in a store now and even with the blank firmware they've confirmed there is a hardware problem.

The fact that if you search just "14.7.1" the first 3 news article results are about the "no service" issue being experienced by many users shows that it's not an isolated problem and not just a coincidence. My guess is that since Apple rolled out the 14.7.1 update to address serious zero day security exploits they became aware of, they rushed it without adequate testing that is resulting in damage to hardware for some users. There are many other reported problems with this update including many people reporting massive battery drain (e.g. from 100% to 0% in a few hours) and issues with FaceID no longer working. I wouldn't be surprised if under certain circumstances the software changes they've made is resulting in too much voltage being drawn by certain components (thus the huge battery drain and damage to hardware). Just because its not affecting 100% of users doesn't mean it's not from the software update, there's probably specific edge cases or circumstances in which it happens.

So if anyone reads this and has the same problem. Restoring your phone exactly as the above troubleshooting advice says will just result in a factory settings phone that still can't get service and won't activate so it cannot be restored or setup again, so even less useful than a phone that only works on wifi.

Go to settings -> general -> VPN & Device managements.

Manually delete ALL configuration profiles except for profile called "iOS 15", since you have it already

In my case, it was the only method that worked.

When restoring to factory settings you need to have a SIM card in the phone and it can’t be in airplane mode. You need Wi-Fi to download the update and a cellular network connection to activate.

No service after 14.7.1 update was fixed by my provider HOT in Austria with fill in “webaut” in APN. See attached screenshot.

Hope can help you.
