Before troubleshooting, check and ensure that your account status is good and all your services are active. To get this done, you will need to contact your service provider or carrier. Also check and ensure that there are no outages that may be affecting network services in your place. You also can get this information from your network service provider. If the No Service error persists, even when there are no outages and everything is good with your account and services, then you may go ahead and troubleshoot software problems on your iPhone 8 Plus that trigger such a network error to occur.

First solution: Remove and reseat the SIM card on your iPhone 8 Plus.

Although the No service error instigated after updating your iPhone to the latest iOS version, it’s still possible that the error is attributed to a bad SIM card. To rule this out, removing and reinstalling the SIM card can help. Here’s how it’s done:

  1. Turn off your iPhone completely.
  2. With your phone powered off, insert the SIM eject tool or small paperclip into the provided slot on the SIM card tray to unlock it. The SIM tray is located on the right edge of your phone.
  3. Remove the SIM card from the SIM card tray. Examine the SIM card for any visible signs of damage. If everything looks good, then place the SIM card back into the SIM card tray.
  4. Position the SIM card with the gold contacts facing down.
  5. Insert the SIM card tray.
  6. Press in on the tray to lock it into place.

When the SIM card tray is locked in place and secured, turn on your iPhone and see if the No service error is gone.

Second solution: Reset network settings on your iPhone 8 Plus.

The new iOS update might have automatically altered your iPhone’s network settings and eventually resulted to a conflict. To clear this out, resetting the network settings can help. Doing so will restore the default network configuration and lets you modify your network settings based on your previous preferences, before the No service error occurs. Here’s what you should do then:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset Network Settings from the given options.
  5. If prompted, enter your device passcode to continue.
  6. Then tap Reset Network Settings again to confirm.

Your will then instigate the network settings reset and then reboots by itself when done. After it reboots, you will need to reconnect to your Wi-Fi network to use the Internet again.

Third solution: Update carrier settings on your iPhone 8 Plus.

Carrier settings update are pushed by your carrier or service provider for network enhancements and offer fix patches to address cellular network connectivity issues. These updates also add support for Wi-Fi Calling and VoLTE. Usually, you will be prompted with a carrier setting update notification if it’s available. If you don’t get any, then you can manually check for and install a carrier settings update with these steps:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap About.
  4. Remain on the About page for at least 10 seconds and wait for an update notification. If nothing shows up, then it means that your carrier settings are up to date.

If you don’t have Wi-Fi Internet access, you can connect your iPhone 8 Plus to a computer and then check for available update carrier settings update using iTunes.

If your iPhone 8 Plus is still showing No service after updating carrier settings, then you may have to consider opting for an iOS reset. System data corruption can also trigger occurrence of a No service error on your iPhone.

Fourth solution: Reset your iPhone 8 Plus to factory defaults.

A factory reset can be considered among the last options if the No service error continues to show up after applying the previous solutions. There may be some fatal system data corruption that caused conflict on the network system and the No service error is the visible symptom. Performing a master reset can help wipe these complex system errors and allows your device to have a clean fresh start. Just be sure to back up all your critical data beforehand because they will also be deleted in the process. Whenever you’re all set, follow these steps to factory reset/master reset your iPhone 8 Plus:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Erase all content and settings from the given options.
  5. If prompted, enter your device passcode to continue.
  6. Then tap the option to confirm factory reset.

Your iPhone will then start wiping data and then restore your iPhone 8 Plus to its factory defaults. After the reset, your device reboots. By then you can proceed with the initial setup process and set up your iPhone as new.

Fifth solution: Restore your iPhone 8 Plus in iTunes.

Another last-ditch solution to consider should a master reset failed to solve the error is a recovery mode restore. In this process, your iPhone will enter in recovery mode and then attempts to restore the system through iTunes. You will need to use a computer to get this done. Here’s how:

  1. Connect your iPhone 8 Plus to your Mac or Windows computer using the original Lightning cable.
  2. When your iPhone is connected, quickly press and release the Volume Up button, then press and release the Volume Down button and finally, press and hold the Side/Power button until the phone reboots. Continue holding the Side/Power button even when you see the Apple logo.
  3. Release the Side/Power button once you see the Connect to iTunes screen.
  4. Go to iTunes and you should see a message saying that “There is a problem with the iPhone that requires it to be updated or restored.”
  5. Select the option to Restore, then follow the onscreen instructions to complete the entire iOS restore process in recovery mode.

If your iPhone 8 Plus still prompts a No Service error after carrying out a recovery mode restore, then your next options would be either to take your iPhone to an Apple authorized service center or report the issue to Apple Support. If you prefer the latter, contact your carrier or Apple Support to escalate the issue for further assistance and recommendations.
