How to fix an iPhone 11 Pro that gets no service error after iOS 13.2.3 update

When your iPhone is getting a no service error, basic functions such as calling and texting would be available. This means you cannot make or receive phone calls and text messages on your device. The underlying cause of the problem may be from within the network base or with your iPhone system. Account-related issues can also be considered among other factors to look into with dealing with these issues. Tackled in this post is a similar problem on the iPhone 11 Pro that’s getting no service error after updating to iOS 13.2.3. Given that the onset of the problem was after a new iOS update installation, it’s safe to say that an iOS bug is likely the main trigger. Nonetheless, it is still imperative to rule out other possible causes. Read on to find out what to do if your iphone 11 Pro gets no service error after installing a new iOS update.

Troubleshooting an iPhone 11 Pro that gets no service error after updating iOS

The following methods will help eliminate common causes of network problems that can trigger the occurrence of no service error on your iPhone. Try these before rushing to a service center.

 

First solution: Restart your iPhone.

Many post-update symptoms are minor that they can easily be remedied by restarting the phone. Performing a soft reset or restart can help fix various types of software errors that caused certain features to suddenly fail or stop working. And this could be all that’s needed to eliminate any existing errors from your iPhone’s network system. Just follow these steps to soft reset your iPhone 11 Pro then:

1. Press and hold both the Side and Volume Up buttons for a few seconds.
2. Release both buttons when the Slide to Power off bar appears.
3. Swipe or drag the bar to turn your device off.
4. After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.

Allow your iPhone to finish rebooting and then see if the no service error is gone. If it re-occurs, try other means to eliminate other possible triggers.

 

Second solution: Toggle Airplane Mode on and off.

Performing the so-called Airplane mode trick can also help fix various types of wireless problems including post-update cellular issues depicted by the no service error. A lot of people have found wonders from doing this trick whenever they’d bump into a network issue, thus it won’t hurt if you’d give it a try as well and see what happens. Here’s how it works:

1. From the Home screen, tap Settings.
2. Select Airplane Mode.
3. Toggle the Airplane Mode switch to turn the feature ON. Doing so disables your iPhone’s wireless radios and associated features like Wi-Fi and Bluetooth.
4. While Airplane Mode is turned on, reboot or soft reset your iPhone to clear out network cache.
5. After it reboots, go back to Settings-> Airplane Mode menu.
6. Then toggle the Airplane Mode switch to turn it OFF again.

After turning off Airplane mode, wait for the Wi-Fi signal to stabilize and then see if that eliminates the no service error from the status bar.

 

Third solution: Update carrier settings to fix your iPhone 11 Pro that gets no service error after an update.

Network-related problems including those that are triggered by a firmware update can also be resolved by installing carrier settings update on your iPhone. These updates are developed and rolled out by your service provider/carrier as their way of keeping the network system free from flaws and more optimized. If your iPhone has no problem connecting to the internet, then you can use these steps to do a quick check on any available carrier settings update you can install on your iPhone:

1. From the Home screen, tap Settings.
2. Select General.
3. Tap About.

Navigate to the carrier section then see if a new carrier update notification shows up. If an update is available, read and review the information then follow the onscreen instructions to update carrier settings on your iPhone.

Fourth solution: Reset network settings on your iPhone.

Performing a network reset may also be necessary if network settings errors are the underlying cause of the problem. This reset will erase all your current network configurations including faulty network overrides from the recent update that triggered the no service error. It doesn’t affect any saved information though so you don’t need to back up your iPhone data beforehand. Just follow these steps to proceed:

1. From the Home screen, tap on Settings.
2. Select General.
3. Scroll down and tap on Reset.
4. Tap Reset network settings from the given options.
5. Enter your passcode if prompted to continue.
6. Confirm action by tapping the option to reset network settings again on your device.

When the reset is finished, your phone restarts and then loads up the default network values and options. This means you’ll have to enable Wi-Fi to reconnect to your network and get back online. Aside from Wi-Fi, other features that are disabled by default must also be re-enabled individually for you to be able to use them when needed.

Fifth solution: Remove then reinstall the SIM card on your phone.

Reinstalling the SIM card can also help fix the problem if the error is tied to a corrupted SIM card system or perhaps a dislodged SIM card. Here’s how you do it:

1. Turn off your iPhone completely.
2. While your iPhone is turned off, insert the SIM ejector tool into the small hole on the SIM tray located on the side of your phone. You can also use a small bent paper clip as an alternative if you don’t have the ejector tool.
3. Gently push the ejector tool until the tray ejects.
4. Remove the tray from the phone then take the SIM card out.
5. Examine the SIM card and tray for any visible signs of damage like scratches or liquid traces.
6. If everything looks good, place the SIM card back into the tray in the same orientation before you removed it.
7. Secure the SIM card then push the tray back into the phone until it locks in place.

Turn your iPhone back on and see if the no service error is gone.

 

Last resort: Restore factory default settings on your iPhone.

The last option you can go for if all else failed to solve the problem would be a factory reset. This will wipe everything from your iPhone system including stubborn iOS bugs that ruined the cellular network system and trigger the No service error to show up instead of getting cellular signal bars. Just don’t forget to back up all critical data from your iPhone to iCloud or iTunes beforehand. Once you’re all set, follow these steps to erase your iPhone and restore factory default settings:

1. From the Home screen, tap on Settings.
2. Select General.
3. Scroll down and tap on Reset.
4. Tap Erase all content and settings from the given options.
5. Enter your passcode if prompted to continue.
6. Confirm action by tapping the option to erase and reset your iPhone.

You can also use iTunes to factory reset your iPhone 11 Pro. This can be a better option if your iPhone is enduring other system issues aside from a flawed network system. If a factory reset still failed to fix the problem, restoring your iPhone from a previous iOS backup can be deemed among the next option. Performing a system restore is usually needed to deal with major post-update bugs that could not be remedied by some basic workarounds.

What to do if your iPhone 11 Pro still shows no service error?

If the no service error continues after applying all the above solutions, there’s a good chance that the problem is from within the network base. This is usually the case of a temporary network outage is transpiring and cellular network services are affected. To check on that, you can contact your service provider/carrier and ask them to check their outage board. 

Meanwhile, if you suspect that the no service error is due to a faulty SIM card on your iPhone, asking for a new SIM card replacement from your carrier can be a better option. If your carrier supports an eSIM, then getting an eSIM subscription is also another option. 

For further assistance in carrying out more advanced solutions, you can escalate the problem to Apple Support.
