Changing phone number in iMessage on phone and iPad

Hi robertfrombeaufort,

Thanks for coming to Apple Support Communities for help removing your number from iMessage on your iPhone and iPad.

This page should be able to help: Add or remove your phone number in Messages or FaceTime

"Remove your phone number

If you don't want calls or messages for your iPhone on your iPad, iPod touch, or Mac, you can remove your phone number. There are two ways to do this:

• On your iPhone, go to Settings > Messages > Send & Receive. Select your Apple ID at the bottom of the screen and tap Sign Out. Then go to Settings > FaceTime, select your Apple ID and tap Sign Out.
• If the phone number that you want to remove belongs to an iPhone that you can't access, change your Apple ID password. This removes all phone numbers from your iPad, iPod touch, and Mac. Calls or messages for the removed numbers won't appear on those devices anymore."

It can take up to 24 hours to activate iMessage: If you get an error when trying to activate iMessage or FaceTime.

Have a fantastic day!
