Is iMessage not working on your iPhone running iOS 15 or 14? Don’t worry, many other users encounter this issue from time to time. It could be due to wrongly configured settings, the carrier not supporting the message you’re trying to send, poor internet connection, etc. 

Let’s dive in and take a look at the quick solutions!

Quick Tips:

  • Delete old conversations: One user on the Support forum noted that deleting old texts got iMessage working again. Strange, yes, but sometimes tricks like this work.
  • Set Date & Time Automatically: A reader has noted that setting the date to automatic fixes the issue. To do so, open Settings → General → Date & Time and toggle the switch Set Automatically to on.

If the above tips didn’t work out, try the following solutions:

  2. Restart iMessage
  3. Sign out of your Apple ID and sign back in
  4. Set your phone number to Send and Receive Messages
  5. Update iOS
  6. Restore your device and set it up as new

1. Check your internet connection

First off, you must ensure you have a proper internet connection on your iOS device. iMessage may not work if there is poor Wi-Fi or cellular connection.

Turn Airplane Mode on/off

On some occasions, you may be able to fix the issue by simply turning Airplane Mode on/off. If your iPhone has a home button, swipe up from the bottom of your device to access Control Center and then tap the Airplane Mode button.

On an iPhone X or later (no home button), swipe down from the top right corner and then tap on the Airplane Mode button to turn it on. Wait for some time and then turn it off.

Turn Wi-Fi/Cellular on/off

Go to Setting → Wi-Fi/Cellular → Toggle it off. Now, restart your iPhone.

Once your device has restarted, turn on Wi-Fi/Cellular and try to send iMessage again.

If you’re using Wi-Fi, forget the network and reconnect your device to it.

  1. Open Settings → Wi-Fi.
  2. Tap the i button next to the network.
  3. Tap Forget This Network and tap Forget in the popup to confirm.

Then, force reboot your iPhone. To do so, press and hold the Home and sleep/wake buttons together until the Apple logo shows up on the screen.

On your iPhone X or later, press and release the volume down button, then press and release the volume up button. Next, press and hold the side button until you see the Apple logo appear on the screen.

Then, turn on iMessage and wait for the activation to finish. If it’s working again, you’re good to go. If it hasn’t, move on to the next solution.

3. Sign out your Apple ID and sign back in

Try signing out of Apple ID and then signing back in. Here’s how:

  1. Open Settings → Messages → Send & Receive.

    Tap on Send & Receive in Message Settings on iPhone
  2. Tap your Apple ID and tap Sign Out.

    • Selecting either email or iPhone to test if iMessage works with any of these
    • Select an email AND a phone number. After this, you’ll see another section Start New Conversion from:, select your phone number for this

5. Update iOS

Keeping iOS up to date is one of the best ways to make sure your iPhone stays bug free. Many times I have successfully fixed annoying issues like an autocorrect bug or the camera focus issue just by updating my device. That’s why I suggest you give it a shot as well.

Open Settings → General → Software Update. If there’s an update available, tap Download and Install.


6. Restore your device and set it up as new

If the problem hasn’t resolved itself after trying out all the aforementioned tricks, restore your iPhone using iTunes and then set it up as new. Before going for the kill, don’t fail to back up your device.

Simply connect your iPhone to your computer → fire up iTunes or Finder and hit the Restore button.
