Troubleshooting an iPhone 11 Pro no service error

As mentioned earlier, most of the possible causes of this error are software-related. This means that the problem can be rectified at home by some basic troubleshooting procedures. But before you begin to troubleshoot your device, make sure you are within your network’s coverage area and that your account services are active. If you aren’t sure about the current status of your account, you can always give your service provider/carrier a call for further verification. If all these criteria are met but your iPhone 11 Pro is still showing a no service error, then you may now go ahead and start ruling out common software-related factors.

Also consider removing any protective casing from your iPhone, especially third-party made accessories as they could also interfere with the cellular network signal.

First solution: Reboot your iPhone.

Performing a soft reset or reboot on the phone can fix various types of software problems inflicted by minor bugs and glitches. If the no service error only shows up right now, then it’s probably just a random network system glitch. That said, rebooting the phone may be the only thing that’s needed to get rid of the error. So here’s what you should do first:

  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 phone to finish rebooting and then see if the no service error is gone.


Second solution: Toggle Airplane Mode on and off.

Another simple solution to random network errors is the Airplane Mode trick. It works by giving a simultaneous restart on your iPhone’s wireless functions. Here’s how it’s done:

  1. From the Home screen, tap Settings.
  2. Scroll down and tap on 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.

Give your phone a few seconds to re-establish wireless signal and then see if the no service error is gone. If it still shows up, try other means to rule out other possible triggers.


Third solution: Install carrier settings and iOS updates to fix your iPhone 11 Pro that’s prompting no service error.

Network system bugs that trigger relevant errors are the next factors to eliminate. And the next potential solution to these errors is a carrier update. It is a separate update from that of the iOS. This update is created and rolled out by your carrier to enhancement network services and to strengthen network security of your device. Some carrier updates are dedicated to fix widespread network errors affecting many iOS devices. If your iPhone doesn’t have trouble connecting to the internet and that the connection is stable, follow these steps to manually check and install pending carrier updates on your iPhone 11 Pro:

  1. From your 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

Another update you should consider implementing is the firmware update coming from Apple itself. Software updates or iOS updates rolled out by Apple usually integrate some dedicated fix patches to get rid of widespread problems inflicted by some system bugs. If you haven’t set your device to auto-install updates, then you can do it manually with these steps:

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

If a new iOS version is available, you should see a notification containing the update details and other system information. Read and review the details then follow the onscreen commands to download and install the update on your phone.


Fourth solution: Reset network settings on your iPhone.

Network problems that could not be dealt with by basic solutions usually require some resets. In this case, carrying out a network settings reset on your phone can help. Doing so clears out all your current network configuration and preferences along with any transpiring network errors. Just follow these steps if you wish to proceed with this reset:

  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

After the reset, you will need to set up your Wi-Fi network to get back online. Re-enabling necessary features, particularly those that are disabled by default is also needed.


Fifth solution: Reinstall the SIM card on your iPhone.

A corrupted SIM card system or dislodged SIM card in the phone’s SIM card tray may also be the main reason why your iPhone keeps showing a no service error. To clear this out, remove then reinstall the SIM card on your iPhone 11 Pro. Just follow these steps:

  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 in place. 

Turn your iPhone back on after securing the SIM card tray and then see if the no service error is gone. If it still shows up, then you may have to consider performing further system resets.


Last resort: Erase your iPhone and restore its factory default settings.

A factory reset wipes everything from your phone system including downloads and saved information on your iPhone storage. This reset is usually deemed among the last options when dealing with recurring symptoms, particularly those that were attributed to some complex system errors. If you wish to continue and factory reset your iPhone, be sure to back up all your critical data beforehand. You can back them up to iCloud or iTunes as you desire. Once you’ve got the back up secured, follow these steps to factory reset your iPhone 11 Pro through settings menu:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Select the option to Erase all content and settings. This will erase everything from your iPhone system including all saved data on the internal memory.
  5. Enter your device passcode if prompted to continue.
  6. Then tap the option to confirm that you want to erase your device.

Wait for your phone to finish wiping data and restore factory default settings. After the reset, you can proceed with the initial setup process to set your iPhone up as new. Just use the startup wizard to utilize automatic settings for the features needed to re-activate on your phone.

Is your iPhone 11 Pro still showing no service error?

Network problems that could not be resolved by any of the above procedures are usually due to some temporary service outages or scheduled maintenance conducted by your network service provider. In other words, the problem is not with your iPhone and therefore it could not be resolved on your end. In this case, all you can do is to wait until the outage is over and the network services resume. 

If you suspect that the problem is attributed to a damaged SIM card, try to insert your SIM card to your other compatible device and see if the error shows up. If the no service error doesn’t appear on your other devices wherein the same SIM card is inserted, then it means the problem is with your iPhone. There might be some complex errors transpiring on the network system. For more advanced solutions and official suggestions, you can escalate the problem to your network service provider or Apple Support.
