Fix iOS 17 No Service Issue After Upgrade, Here’s How

Here’s how to fix iOS 17 No Service issue after the upgrade of the firmware on your compatible iPhone device.

Now that iOS 17 is in the hands of people all around the globe people are beginning to install the update in numbers that simply hasn’t happened during the beta program. But that unfortunately also means that there are some issues starting to crop up.

One of those issues causes users to see No Service after updating their iPhones and then completing the final restart.

If you do find yourself in a position where your iPhone has been updated to iOS 17 but simply won’t connect to your carrier, here’s what you can do to try and kick things into gear.

Toggle Airplane Mode On & Off

Sometimes cycling the cellular modem can be enough to make your iPhone connect to your carrier, so give that a try first.

Restart iPhone

A full restart of your iPhone can often be required to kick things back into gear, and it’s definitely something to consider if the airplane mode trick didn’t work.

Check SIM card

This will only work if your iPhone has a SIM card of course, but if it does we’d suggest removing it and then reinserting it to see if that gets things working as they should.

Reset Network Settings

This isn’t a fun option, but it might work. Open the Settings app and go to General > Reset > Reset Network Settings and confirm. This will wipe all of your network settings, including WiFi passwords.

Reset iPhone

It’s a nuclear option, but it might be the only way to go. It resets all of your network settings and can sometimes be what’s required to make your device connect to your carrier again.

Contact Apple

If none of the tips above work we’d suggest reaching out to Apple. You can do that in a variety of ways but going to your local Apple Store can be the easiest option.
