My iMessage does not register my phone number

Hey George_Vee,

Thanks for using Apple Support Communities. If you do not see your phone number in the Messages settings, these steps should help to get it set up. Start with "Set up your phone number" and if needed, the steps under "If you can't see or select your number in Messages or FaceTime" here: Add or remove your phone number in Messages or FaceTime - Apple Support

If instead you're seeing an activation alert, this guide can help: If you can’t turn on or sign in to iMessage or FaceTime - Apple Support

Let us know how it goes.

Take care!
