2 installments one 1 sim
So 2 years ago I preordered the note 20 ultra with a trade in promotion. I am Currently still paying the phone off and now I want to get the 13 pro max. So I was wondering if I could keep my note 20 ultra on the installment plan and get the 13 pro max. Keeping the same phone number and still be receiving the bill credit for my note 20 ultra. Without adding a new line. Like keeping the phone installment on the note 20 and moving the data plan payment over to the 13 pro max. Btw my current carrier is ATT.
I hope this makes sense
