The iOS 13 update brings in a number of new features along with necessary system enhancements. But like other prior updates, it also entrenched unwanted bugs that result in the onset of various post-update problems on the receiving devices. Tackled in this post is a relevant issue on the iPhone 8 that keeps showing no service error after the iOS 13 update. Problems like this typically require immediate solutions given that core functions, particularly calling and texting services are primarily affected. Read on to find out what to do if your iPhone 8 keeps showing no service error in iOS 13.

Troubleshooting an iPhone 8 that keeps showing No service error in iOS 13

The following procedures will help eliminate software-related factors that might have triggered your iPhone to keep showing a no service error after the iOS 13 update implementation. Try each of these lined up solutions to determine the underlying cause, get rid of the no service error and be able to process calls and SMS services on  your phone again.

First solution: Remove then reinsert the SIM card

No service error, searching, and other related errors can also be attributed to a corrupted SIM card on your device. This is a possible occurrence from a major system update. Fortunately, such flaws can easily be rectified by reinstalling the SIM card on your iPhone. Here’s how it’s done:

  1. Turn off your iPhone completely.
  2. While the phone is turned off, insert the SIM ejector tool into the small hole on the SIM tray located on the side of your phone.
  3. Gently push the tool until the tray ejects.
  4. Remove the SIM card from the tray. Also care to examine the card for any visible signs of damage like scratches and liquid traces. If there’s none, place it back into the tray in the same orientation before you removed it.
  5. Make sure the SIM card is properly seated.
  6. Then push the tray back into the phone until it locks. 

After securing the SIM tray in place, you can turn your iPhone back on again and see if the No service error is already gone.

Second solution: Force restart your iPhone

If your iPhone 8 still shows a No service error after performing the first solution, it’s possible that it got stuck when attempting to re-establish network connection and that has triggered the No service error. In this case, performing a force restart on your iPhone 8 would be necessary. Stuck problems are usually addressed through this method thus, it won’t hurt if you’d give it a shot. Just follow these steps:

  1. Press and release the Volume Up button quickly.
  2. Press and release the Volume Down button quickly. 
  3. Lastly, press and hold the Side button for a few seconds until you see the Apple logo.

Allow your device to finish booting up then see if the No service error is gone.

Third solution: Use the Airplane mode trick to fix your iPhone 8 that shows no service error in iOS 13

This old trick has been proven by many to work wonders when dealing with random problems affecting wireless network services. It works by simultaneously restarting the phone’s wireless features and thereby eliminates minor flaws affecting relevant services. If you wish to try your luck in this trick, then you may by following these steps:

  1. Tap Settings from the Home screen. 
  2. Select Airplane mode
  3. Toggle the switch next to Airplane mode to turn the feature on. All wireless functions of your phone are then disabled simultaneously.
  4. While the Airplane mode is enabled, perform a soft reset on your phone. 
  5. Wait until your phone is finished rebooting and then go back to Settings-> Airplane mode menu. 
  6. Finally, tap the Airplane Mode switch again to disable the feature.

Allow your device to re-establish network signal and see if that fixes the No service error on your device. 

Fourth solution: Update carrier settings on your iPhone, if possible

Carriers also push separate updates to keep network services more stable and bug-free as possible. Some of these updates are automatically installed while others require manual implementation. If your iPhone has Wi-Fi internet access, then you can manually check and install available carrier settings update for your iPhone 8. Just follow these steps to get started:

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

If you see an option to update your carrier settings, then that means an update is available and your device is eligible. Just follow the onscreen instructions to start installing new carrier updates for your iPhone 8.

You can also ask your carrier for further assistance in updating your iPhone’s carrier settings, if necessary.

Fifth solution: Reset network settings on your iPhone

Network-related errors including no service error from the iOS 13 update can also be addressed by performing a network settings reset on your device. This will erase all existing network configurations including faulty network settings overrides from the recently installed update on your phone. It doesn’t affect any saved information on the internal memory, so it’s a safe process to carry out even without backing up files on your device. Just follow these steps if you wish to take your chances in this reset:

  1. From your Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap on Reset.
  4. Select Reset Network Settings from the given options.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to reset network settings on your phone.

When the reset is finished, your phone restarts automatically and then loads up the original network values and options. To reconnect to the Internet, you’ll need to re-enable Wi-Fi and set up your Wi-Fi network as new.

Last resort: Restore your iPhone to its factory default settings

If all else failed to resolve the issue and your iPhone 8 still shows the same No service error, resorting to full system resets and iOS restore can be considered among the last options. These methods are usually applied to eliminate major system errors including stubborn iOS bugs that ruined your iPhone’s network system and resulted in a recurring No service error. If you wish to troubleshoot further, your next option would be a factory reset. Doing so will erase all data from your iPhone and then restore its factory default settings. Complex system errors are usually addressed through this reset, so you’ll have a greater chance of getting rid of the No service error after the reset. You can use iTunes to back up your iPhone data to your computer before erasing it through iTunes. Just follow these steps whenever you’re all set to reset and restore your iPhone 8:

  1. Open iTunes on your computer, if you haven’t already. Be sure to use the latest version of iTunes software to avoid system conflicts.
  2. Connect your iPhone to the computer using the USB cable and Lightning cable that came with it.
  3. Wait for your iPhone to show up in iTunes and then click on its icon to select it.
  4. Scroll to the Summary section then click the Restore [iPhone] button.
  5. If prompted, click the Restore button again to confirm.

If a factory reset still failed to fix the problem and the No service error continues, restoring iOS in recovery mode or DFU mode can be deemed among the next options and potential solutions. These are more advanced procedures that are used to deal with major iOS problems and update bugs that could not be rectified by basic iOS troubleshooting procedures. Both these methods will result in permanent data loss, hence backing up files beforehand is highly recommended.

A comprehensive guide on now to restore an iPhone 8 in recovery mode or DFU mode can be found on this site’s tutorials section. For more information, just visit the iPhone 8 troubleshooting page on this website.

Is your iPhone 8 still showing no service error in iOS 13

If the no service error continues to show up on your iPhone 8 after performing all prior methods, then it could be due to some ongoing network issues like a temporary network outage affecting network services in your place. You can report the problem to your carrier or network service provider so that they can check their outage board for any ongoing outages. Also care to check your account status and make sure that all your outgoing services are in good status or active. Account-related issues may also be the main reason why outgoing services are temporarily disabled or unavailable for your account.

For further assistance and official suggestions, you can escalate the problem to Apple Support. Should this be found and proven to be an iOS 13 bug, Apple would be obliged to develop and roll out follow-up update containing the fix patch.
