I recently added a line and gave that person my old iPhone. I setup the new phone under my number and switched the sim cards per the AT&T sales person. Now when my family and friends try to text me, the messages are going to the other person with my old iPhone. They have the new sim card and I have my old sim card from the iPhone. How can I fix this so messages being sent to me, come to me and not the other person?? Thank you!
They aren’t going to the number, they are going to your Apple ID.
If you get that sign out of and factory reset your old phone, and set up the new user with their own Apple ID. Please make sure that it’s done right away. Do you want to remove all of your information, your iTunes and your Apple ID from any device you’re no longer using. Turning off find my iPhone and factory resetting the device per apples directions
