Did you deregister your old device?
Below is from Apple site.

When activating iMessage or FaceTime, you might see one of these messages:
- Waiting for activation
- Activation unsuccessful
- An error occurred during activation
- Could not sign in, please check your network connection
- Unable to contact the iMessage server. Try again.
Check your device settings
Make sure that you’re connected to a cellular data or Wi-Fi network. If you're using an iPhone, you need SMS messaging to activate your phone number with iMessage and FaceTime. Depending on your carrier, you might be charged for this SMS.
Go to Settings > General > Date & Time and make sure that your time zone is set correctly.
Turn off and restart iMessage and FaceTime
Go to Settings > Messages and turn off iMessage.
Go to Settings > FaceTime and turn off FaceTime.
Restart your device:
iPhone
iPad
iPod touch
Turn iMessage and FaceTime back on.
Still not activated after a day?
It might take up to 24 hours to activate iMessage and FaceTime. If the issue continues after 24 hours, follow these steps:
- Make sure that your device has the latest version of iOS or iPadOS.
- If you're using an iPhone, contact your carrier to make sure that you can send and receive SMS messages.
- If your iPhone is used with a carrier not found in the wireless carrier articles make sure you can send and receive international SMS.
- Contact Apple Support.
