iMessage is Apple's messaging service. Users can use it to send text messages, photos, videos, and more. This service uses Wi-Fi or your device's cellular data. When you send a message, a blue bubble will appear for iMessage conversations, and a green bubble will appear for others.
However, many users have recently been facing the iMessage activation failed error. Continue as we troubleshoot iMessage activation errors.
Why does my iPhone keep saying iMessage activation error?
If you're facing the iMessage activation error, you won't be able to send or receive regular text messages. Your messages will have a green SMS bubble instead of the blue iMessage bubble.
However, in many cases, you may be unable to send or receive text messages at all. If that's the case, continue, as we will be covering some fixes that will help fix the iMessage activation error.
Fix iMessage Activation Error on iPhone
Let’s start fixing the iMessage activation error with the most basic fixes: restarting your iPhone, checking your device’s internet connection, and changing the date and time settings. However, if these don’t help, continue with these fixes.
Check if iMessage is turned on

If iMessage is turned off, it can cause errors during iMessage activation. Here's how:
- Open Settings, navigate to Apps, and tap on Messages.
- Here, turn the toggle beside iMessages to On.
If iMessage is enabled, try switching it off and turning it back on.
Set your Apple ID to Send & Receive iMessages

If an error occurred during iMessage activation, check if your Apple ID is set to Send & Receive messages. If your Apple ID isn't set as the default, an iMessage activation error may occur on your iPhone. Here's how you can check it:
- Open Settings, navigate to Apps, and tap on Messages.
- Here, click Send & Receive and ensure your phone number and email are selected.
Check iMessage system status

Next, check the iMessage system status and verify if the iMessage service is up and running. These servers can face downtime, causing the iMessage activation failed error. Visit Apple’s system status page and check if the services are up and running. The green dot indicates the service is running.
Reset network settings

Lastly, if none of these fixes helped you, consider resetting the network settings of your iPhone. Doing so will delete all saved Wi-Fi passwords and cellular data settings, reverting these settings to factory defaults. Here’s how you can do so:
- Open Settings > General, scroll down, and click on Transfer or Reset iPhone.
- Click on Reset > Reset Network Settings and enter your device's password.
- Restart your device after the reset and see if the iMessage activation error gets fixed.
