How to troubleshoot iPhone XS Max that keeps showing ‘No Service’ error?

Before you start troubleshooting, check and ensure that you’re within your network provider’s coverage area. You’re probably way too far from your network’s cellular tower for your iPhone to get a decent signal. If location isn’t an issue and yet your iPhone XS Max is still prompting a No service error, then it could be attributed to a software issue and so you can go ahead and start troubleshooting.

First solution: Reboot your iPhone XS Max.

If this is the first time you’re getting a No service error on your new iPhone, then it’s probably just a random glitch affecting the network functions. In that case, performing a soft reset or reboot on your iPhone XS Max will take care of it. For starters, a soft reset/reboot on the iPhone XS Max is carried out through these steps:

  1. Press and hold the Side button and either Volume button simultaneously for a few seconds.
  2. Release both buttons when the Slide to Power off command appears.
  3. Drag the Power off slider to the right to turn off the phone.
  4. After 30 seconds, press and hold the Side button again until the Apple logo appears then release.

Restarting your iPhone’s cellular data feature can also help. Doing so clears out minor glitches transpiring on the phone’s cellular functions and eventually triggers a No service error to occur.

  • To do so, go to Settings-> Cellular -> then toggle the Cellular Data switch to turn the feature on or off.

Cellular data must be turned on to enable and use cellular services on your device including basic texting and calling functions.

Second solution: Check and install carrier settings update on your iPhone XS Max.

If your phone can access the Internet, then you can try checking for any available carrier settings update to install on your device. This would be necessary especially if you happen to switch to or use a new SIM card in your iPhone Xs Max.

  • To do so, head over to Settings-> General-> About section and wait for a notification prompt to appear. If a carrier settings update is available, you will be prompted with an option to update carrier settings. Just follow the onscreen instructions to apply the new update.

Installing the latest iOS version available for your iPhone XS Max can also help fix the error especially if software bugs have something to do with it.

  • To check for new iOS update on your iPhone XS Max, go to Settings-> General-> Software update menu. If you see an update notification, follow the given instructions to download and install update on your phone.

Don’t forget to reboot your iPhone after installing updates either carrier settings or iOS. Doing so will ensure that all new system changes are properly applied.

Note that a stable Wi-Fi internet connection is necessary to download and install OTA updates, so make sure your Internet is fine.

Third solution: Reset network settings on your iPhone XS Max.

A network settings reset can also be considered a potential solution if the error is attributed to invalid network configuration on the phone. Doing so will void all your current network settings and then restore the original values. Here’s how it’s done:

  1. Launch the Settings app.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Reset Network Settings.
  5. If prompted, enter your device passcode to continue.
  6. Then tap the option to confirm network settings reset.

When your iPhone is finished resetting network, it will reboot by itself. After it reboots, the default network settings are loaded. To use the Internet and other network services, you will need to enable individual features through your iPhone settings. See if that fixes the No service error then.

Fourth solution: Remove and then reseat the SIM card on your iPhone XS Max.

A faulty SIM card is also among the underlying causes. Your phone is probably unable to establish cellular feed and therefore prompts a No service error because the SIM card is dislodged or worst, damaged. To rule this out, try removing and reseating your SIM card with these steps:

  1. Turn off the phone completely.
  2. Locate the SIM tray on the side of your iPhone XS Max.
  3. Then insert the SIM ejector or paper clip into the small hole beside the tray.
  4. Gently push in towards the phone to eject the card tray. Don’t force it to prevent causing damage.
  5. Remove the SIM card from the SIM card tray. Check the card for any visible signs of damage like scratches or liquid traces. If everything looks good, place the SIM card back into the SIM card tray in the same position before you remove it.
  6. When the SIM card is secured in place, push the SIM card tray back in until it clicks into place and is flush with the side of the phone.

Then you can turn your iPhone back on and see if the No service error is already gone. If it persists, then you’re likely dealing with a fatal error that requires more advanced solutions. At this point, you may resort to performing system resets as your last options.

Fifth solution: Wipe your iPhone XS Max then restore factory default settings.

Restoring your iPhone XS Max to its factory default settings is often needed to deal with reiterating software issues and errors. Recurring issues are usually due to more complex system errors that often requires a full system reset. If you’d like to proceed, then you may opt for a master reset or factory reset. Here’s how it’s done:

  1. Open the Settings app.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Erase all content and settings.
  5. If prompted, enter your device passcode to continue.
  6. Then tap the option to confirm master reset on your iPhone XS Max.

Let your iPhone finish resetting and then reboots automatically. After it reboots, you can continue with the initial setup process to set up your iPhone as new.

Does your iPhone XS Max still show the same No service error?

If none of these helps and the No service error remains prompting on your iPhone Xs Max display, then you should now have the problem escalated to your network service provider or carrier. That way they can make further assessments on their end and figure out an ultimate solution. Should the problem be attributed to a bad SIM card, then they can advise you to get a new SIM card replacement that’s provisioned with the correct service plan for your account.

For other options and advanced solutions, you can also reach out to the Apple Support department. Just let them know the important details of the problem you’re facing and what you’ve done so far in attempting to solve the problem on your end. But if calling support doesn’t offer that much help, you can just visit the nearest Apple service center and have your iPhone XS Max carefully assessed by an iPhone technician instead.
