How to troubleshoot iPhone 8 Plus with iMessage that’s not working properly

While this may have started following an iOS update installation, it’s still important to check and ensure that outage isn’t to blame. It may have just occurred coincidentally that the iMessage service went down because of server errors. To check on the current iMessage service status, go to the Apple support page system status page. This page can be accessed through the official Apple Support website. On this page you can find a list of all Apple services including iMessage with individual status indicator next to them. If the status indicator next to a service is green, then it means the service is up and running. But if it is gray, it means the service is currently not available. Locate iMessage and check its status indicator. If it’s unavailable, then you’ll have to wait until the service resumes. There’s nothing you can do on your end in that case because the problem is likely with the Apple servers. If iMessage service status says it’s available and yet it’s not working on your phone, then this is when you need to troubleshoot.

First off, check and ensure that the data and time settings on your iPhone 8 Plus are correct. Your iPhone must have stable Internet connection either through Wi-Fi or cellular data network. If you’re relying on cellular data for iMessage, make sure you’ve got enough data allowance left in your account and that your phone must have a 3G or 4G connection. Once you’ve got all these requisites met, try to create a sample iMessage to send and receive on your iPhone. If it still failed, continue to troubleshoot your iPhone software with the following procedures.

First solution: Soft reset/restart your iPhone 8.

If you haven’t restarted your iPhone yet after installing the new update, then it’s possibly just glitching. This could be a minor post-update hiccup that can easily be remedied by restarting the phone system. So here’s what you should do then:

  1. Press and hold the Power button until the Slide to Power Off command appears.
  2. Drag the slider to the right to turn your iPhone completely off.
  3. After 30 seconds, press and hold the Power button until the Apple logo appears and then release.

Allow your device to finish restarting and then launch iMessage to test and see if it’s now working fine.

Second solution: Turn iMessage off and on.

This trick can also help clear minor glitches afflicting the iMessage system on the phone. Should you wish to try it, then follow these steps:

  1. Navigate to Settings from the Home screen.
  2. Tap Messages.
  3. Scroll to and tap the iMessage switch to turn it off shortly and then tap the switch again to turn iMessage back on.

After doing so, restart your iPhone to dump cache and refresh iOS apps and services including iMessage.

Third solution: Delete old conversations and message threads.

It’s possible that you’ve exceeded the message limit and therefore no longer able to receive further messages. In that case, you’ll need to free up space on your message folders by deleting old and unwanted messages. Simply follow these steps:

  1. Open a message conversation.

  6. If you want to delete all messages in a thread, tap Delete All on the upper-left corner instead.

  8. Alternatively, you can swipe left over a conversation to delete a single conversation and then tap Delete twice to confirm action.

Aside from old messages, it will also help if you’d delete unnecessary messages or conversations with attachments. Doing so will ensure that the problem isn’t due to any of the attached files containing some bugs or any sort of malicious software had triggered iMessage to go rogue or stop working. Here’s how it’s done:

  1. Open the conversation.
  2. Tap the blue “i” or information icon in the upper-right corner.
  3. Navigate to Images and Attachments section.
  4. Touch and hold the image or attachment to view options.
  5. Select the option to Delete.

After deleting messages, reboot your iPhone again to clear and refresh the internal memory then check and see if iMessage is already working properly.

All your current network configurations will be deleted, including Wi-Fi settings, Bluetooth connections and APNs. Any errors tied to incorrect settings are likewise cleared in the process. Just follow these steps:

  1. Go to the Home screen.
  2. Navigate to Settings-> General-> Reset menu.
  3. Tap Reset Network Settings from the given option.
  4. If prompted, enter the correct passcode for your device.
  5. Then tap Reset Network Settings again to confirm.

Allow your device to finish the network settings resets and when it’s done, your iPhone will restart automatically. Reconnect to your Wi-Fi or cellular data network and enable other features including iMessage, to use them again on your phone.

Fifth solution: Reset all settings on your iPhone 8.

This process erases all system settings on the phone and restores the default settings without affecting saved data in the internal memory. The new update might have altered your current settings and eventually resulted to an error on the iMessage system. To clear this out, follow these steps to reset all settings on your iPhone 8:

  1. From the Home screen, navigate to Settings-> General-> Reset menu.
  2. Tap Reset All Settings from the given option.
  3. If prompted, enter the correct passcode for your device.
  4. Then tap the option to confirm system settings reset.

Reboot your iPhone once the reset is finished, then set up your network connections to reconnect your device. Then check an see if that fixes the problem with iMessage on your iPhone.
