Troubleshooting calls and SMS problems, no service error on an iPhone 11

Before you start eliminating software-related factors, make sure you are using your iPhone within your network coverage area. A no service error can be an indication that your phone is not getting a signal from your cellular network simply because you are way too far from the base tower. In that case, moving to a different place where cellular signal is available will fix the problem. Otherwise, try any of these solutions.

 

First solution: Turn your iPhone off and then back on.

A no service error can also occur among other random system errors on the phone. Often times, these errors are inflicted by minor glitches that can easily be remedied by a soft reset or iPhone restart. Thus, if the no service error suddenly pops up on your phone’s status bar, try performing a soft reset first. Here’s how it’s done:

  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.

There are also other ways to turn your iPhone off and on. You can use the shutdown option from the settings menu or command Siri to do so. There’s no need to back up files beforehand since this process doesn’t affect any saved data on your iPhone storage. 

 

Second solution: Toggle Airplane Mode on and then off again.

The so-called Airplane Mode trick has also been proven to work wonders when it comes to resolving various types of problems affecting wireless features of an iPhone. It works by simultaneously disabling the wireless features and then enabling them back. Surprisingly, transpiring flaws are rectified as a result. 

  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.

When Airplane mode is disabled, all wireless features are activated but you will need to individually turn other relevant features back on. Just give your iPhone a few moments to re-establish cellular network signal and the signal indicators to stabilize.

 

Third solution: Update carrier settings to fix No service error on your iPhone 11.

Another possible solution to network-related errors including no service is a carrier settings update installation. As the name implies, these updates are released by your carrier or network service provider to address existing network problems that are preventing your device from rendering quality network services. These updates not only offer new network features but more importantly, they embed some dedicated network patches to fix system bugs that caused some troubles to network services. Here’s how to manually check for carrier updates on your iPhone 11:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Tap About.
  4. If an update is available, you’ll be prompted with an option to select OK or Update

You can also use iTunes to manually update carrier settings on your iPhone. Here’s how it’s done:

  1. 400;”>Connect your iPhone to the computer and then open iTunes. Be sure to use the latest version of iTunes app to avoid bumping into some system conflicts.
  2. Wait for your device to sync and back up with iTunes.
  3. Click to select your iPhone 11 Pro when it appears in iTunes.
  4. Navigate to the Summary section and then hold down the Shift key on the keyboard and click Check for Update. Doing so will prompt iTunes to install an iOS image (*.ipsw).
  5. Change the file type to iPhone/iPad Carrier Configuration File (*.ipcc).
  6. Select the desired file and then follow the rest of the onscreen instructions to complete the process.
  7. When the carrier update installation is complete, turn your iPhone off and then disconnect it from the computer.

The next time you turn your iPhone back on, the recent carrier settings updates should be implemented already.

 

Fourth solution: Install new iOS update available for your iPhone 11.

Aside from carrier updates, installing the latest iOS update is also recommended. Updates released by Apple usually contain bug fixes including those affecting network services. If your iPhone has no trouble connecting to Wi-Fi internet and still has ample battery life, follow these steps to check for and implement new iOS update available: 

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

You’ll see a notification if a new iOS version is available. Before updating, you can back up all your important data from your iPhone for safekeeping. Once you’re all set, follow the given instructions to download and install the iOS update.

 

Fifth solution: Perform a network settings reset on your iPhone 11.

Resorting to some settings reset can be considered among the next options if the error persists after performing the previous solutions. There are different types of resets you can do that won’t affect any saved information from your iPhone. But the most applicable would be a network settings reset, given that the problem you’re dealing with is affecting network services. This reset will erase all your current network settings and network preferences. All saved Bluetooth connections and Wi-Fi networks will also be deleted. Any associated errors are likewise obliterated in the process. And here’s how it’s done:

  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 on Reset Network Settings again

Your phone will restart automatically when the reset is finished. By then, you can start re-enabling necessary network features to use them again on your iPhone. Don’t forget to reconnect to your Wi-Fi network to get back online and use the internet on your device.

 

Last resort: Factory reset your iPhone 11.

If all else failed to fix the error, performing a full system wipe out or erasing your iPhone can be deemed among the last options. This reset is usually needed to eliminate complex system errors that caused recurring issues. If you wish to give it a try, be sure to back up all your important files from your iPhone storage to iCloud or iTunes drive beforehand. The fact that this reset will erase your device, makes you end up losing critical data permanently. Once you have secured the backup, you can proceed and carry out a factory reset straight from your iPhone settings with these steps:

  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 on the given option to erase your iPhone

When the reset is finished, your phone will reboot and then restores the factory default settings. To use it again, you will need to set things up like the first time you did. Just follow the start-up wizard to set your iPhone up as new.

Still getting no service error on your iPhone 11?

Applying the above solutions is usually what’s needed to deal with no service error that’s inflicted by software issues on the phone. If the error continues even after performing a factory reset, then there’s a good chance that the problem isn’t on your end. There might be some ongoing network outages that caused random errors to cellular services and thus, your iPhone isn’t able to establish network signal as it usually does. Before escalating the problem though, try to remove and reinstall the SIM card on your iPhone. A dislodged SIM card on the phone can also be the possible reason as to why you’re getting this error. And here’s how you do it:

  1. Turn off your iPhone completely. This is highly recommended to avoid damaging the SIM card components or your phone itself.
  2. While the phone is turned off, insert the SIM ejector tool into the small hole on the SIM tray located on the right 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, insert the SIM card back it into the tray with the gold contacts facing down and the notched edge on the upper right
  5. Make sure the SIM card is properly seated.
  6. Then push the tray back into the phone until it locks. 

After reinserting the SIM card, turn your iPhone back on and see if the no service error is gone already. If it’s still there, then you can now contact your network service provider to verify the current status of your network services and seek further assistance in carrying out more advanced solutions to deal with the no service error you’re getting on your iPhone 11. 

In the case where the no service error is tied to a faulty SIM card, asking for a new SIM card replacement from your carrier would be necessary.
