AT&T Next Up

Right now have a iPhone 17pro with a $30.56 credit and a $30.56 installment.

With next up I can upgrade next year and turn in my phone. Do they remove the remaining balance on the phone in doing so? So my new phone that I get will have a new 36 month balance and new credit whatever that amount is?

I had a couple lines where I didn’t get a full credit and I’m wondering if I trade those in, it would pay off the balance and then I’d upgrade to a new phone, hopefully same $1100 offer applying and thus reducing my monthly bill.

Line 2 installment iPhone 17 = $23.06 and I have a monthly credit of $9.73 since it was an older iPhone that I trade in. Next year if I trade the 17 in and get a $1100 deal again? Would my $23.06 go away and then I’d say get a new phone with a full credit like I have with my other line?
