Hello yall my mother wanted to replace my grandmother (iPhone 12) to a ( iPhone 17 ) and wanted to keep the old iPhone 12 and give it to a family member with a new number. |. Problem is that Apple / AT&T mixed up the numbers… | The new( iPhone 17 ) has the old number but doesn’t not send or receive messages nor call. While the old ( iPhone 12 ) has the new number and receives messages and calls. I’m trying some different methods but I’m all open ears to questions and suggestions and answers. Thank you

iPhone 17 Pro Max / IOS 26
