How can I delete a number registered

iPhone 12, iOS 14
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.
