When you turn on or sign in to iMessage or FaceTime, your device may say that it couldn't sign in or couldn't contact the iMessage or FaceTime server.
If the issue is occurring on your iPhone, follow the iPhone instructions instead.
Make sure your device is connected to Wi-Fi or your wireless network provider's mobile data network, and that you can access the internet.
Check our System Status page to find out whether iMessage or FaceTime is experiencing a service outage.
On your iPad, check in Settings > General > Date & Time.

Go to account.apple.com and sign in with same Apple Account you’re using on your device. If you’ve forgotten your account name or forgotten your account password, resolve that before continuing.
If the issue is with iMessage:
On your iPad, go to Settings > Apps > Messages. If iMessage is turned on, turn it off.
On your Mac, open the Messages app. From the menu bar, choose Messages > Settings, then click iMessage. If you're signed in to iMessage, click Sign Out.
On your Apple Vision Pro, go to Settings > Apps > Messages. If iMessage is turned on, turn it off.
If the issue is with FaceTime:
On your iPad, go to Settings > Apps > FaceTime. If FaceTime is turned on, turn it off.

Restart your device:
Return to the same settings screen to turn on or sign in to iMessage or FaceTime. If you’re signing in, use the same Apple Account that you used in step 1.
Check for VPN and security software. If you installed such software, it could be blocking network ports used by iMessage and FaceTime. If you're not sure, it may help to try again while connected to a different network.
If you receive a message that your email address hasn’t been verified, sign in at account.apple.com and verify the email address. Find out what to do if you can't verify because you aren't receiving your verification email.
If you still need help, the issue may be unrelated to activation or sign-in. Other solutions:
