What Causes iMessage Activation Errors?

When you experience an iMessage activation error, you’ll typically find that iMessage won’t work and that you’ll only be able to send and receive normal text messages (they'll have a green SMS bubble rather than the blue iMessage bubble).

When you experience an iMessage activation error, you’ll typically see one or more of these things happen:

• You can’t send or receive text messages at all
• You can send and receive messages, but your blue text bubbles are green
• iMessage says that text messages haven’t been delivered

It's hard to identify an error until you have solved it, so the tips below should get you blue bubblin' again in no time.

How to Fix an Unsuccessful Activation in iMessage

To fix an unsuccessful activation in iMessage and other iMessage activation errors, attempt each of these solutions in order:

1. Verify iMessage is on. If iMessage isn’t on, it won’t work.

   This fix is unlikely necessary if you received an iMessage activation error, which indicates that it is turned on, but it's incredibly easy to check.

   If you do find that it was off, open Settings > Messages, and check the iMessage toggle. If it’s gray, tap it to turn it on.

2. Restart your iPhone. This is the simplest fix, so it should be one of the first things you try. If your phone is configured correctly and there’s no problem with Apple’s servers, then restarting will typically fix the problem.

   • iPhone X and later: Press and hold the Side and Volume Down buttons, then swipe the Power Off slider.
   • Earlier models: Press and hold Sleep/Wake, then swipe the Power Off slider.

3. Check Apple's server status page. This page displays various Apple services' current status and information about scheduled maintenance periods.

   If iMessage is listed as unavailable or down, all you can do is wait for Apple to resolve the problem. You may need to restart your phone after the servers have come back up.

4. Check your iPhone's internet connection. If you find a connectivity problem, you'll need to fix your iPhone's Wi-Fi connection or figure out why the iPhone has no service, then try iMessage again.

   The solution may be as simple as turning the Wi-Fi and cellular data in the control center off and then on again, or turning off airplane mode.

5. Refresh your iMessage connection. If iMessage has worked in the past, you may be able to fix the problem by refreshing your connection. You’ll need to turn off iMessage, restart your phone, and turn it back on.

   Start by opening Settings > Messages, and tap the iMessage toggle to turn it off. Then restart your phone, open Settings > Messages again, and tap the iMessage toggle to turn it back on.

6. Sign out of Apple ID, then sign back in. Signing out of Apple ID on your phone will force iMessage to reconnect when you sign back in, unless there’s another issue preventing it.

   Open Settings, tap your name, and tap Sign Out. Then restart your iPhone, open Settings, and tap Sign in.

7. Verify your time and date settings. If the time and date on your iPhone aren’t correct, it can prevent iMessage from activating or working correctly. Fix the time and date settings if they’re wrong, then check to see if iMessage works.

   Navigate to Settings > General > Date & Time, and verify that the information is correct. If it isn’t, you can tap the Set Automatically toggle to turn it off and set the time and date manually.

   If the Set Automatically toggle was off, and your time or date was wrong, turning the toggle switch on may fix your problem.

8. Update your iPhone. If your iPhone's operating system (iOS) is outdated, that can prevent iMessage from working correctly. Check for any available updates, install, and then check iMessage.

   You can update your iPhone wirelessly or update the iPhone via iTunes.

9. Factory reset your iPhone. This will delete everything on your device, so make sure to try all of the other fixes and then backup your iPhone before you proceed.

   It can take up to 24 hours for the iMessage Activation Error to resolve, so you may want to wait to see if you’ve already fixed the problem before you attempt a factory reset.

If Apple's servers are up, and none of the fixes worked for you, you'll need to contact Apple support or your cellular service provider for additional assistance. The problem is more likely due to an issue with your carrier if you cannot send text messages at all.
