When I text someone, they receive it from 2 numbers Whenever I text or iMessage someone, they recieve it from both my number from my old phone that I transferred over, and the number on this phone. How do I make sure only 1 number is in use?
Open the Settings app.
Then, go to the "Messages" section.
Then, tap "Send &amp; Receive".

After that, check to make sure that you only have one number checked.
