Moved to smarty Text messaging shows incorrect number solution

Hi gang,

Sitting in a bank waiting. As I have time I have resolved some of my problems re incorrect number texting. People saying your text messages don’t show your name in their contacts. Also the number not the one they have. So when your smarty sim arrived I noticed the number was different to the one I have had since owning a phone. When I call out my number displayed on another person’s phone. But not text. (I am ok IOS) I went to settings/app/ message and deleted the new smarty number. iPhone says remove I say yes. Then it updated to my old number
