Hi I am having issue linking my number to my FaceTime and iMessage and yes I have tried every tip and no I don’t want to use my Face ID. What could be wrong keeps showing error

Face id has nothing to do with it, follow all steps here If you can’t turn on or sign in to iMessage or FaceTime - Apple Support

Well if you gone through all the steps in the link I provided, and Apple support can't help you when you contacted them, then there is nothing else you can do.
