Q: iMessage and FaceTime don't show my phone number what should I do to fix it?

Если при попытке активации iMessage или FaceTime возникает ошибка - Служба поддержки Apple

If you get an error when trying to activate iMessage or FaceTime - Apple Support

unfortunately in my region Apple support isn't working, but my carrier told me that is not under their competence to fix the problems of immesage. I always see the notification of iMessage and I press ok, but anyway don't work.
