I'm still on the old Tab system and have got a positive Tab balance (phone was bought outright years ago). I'd like to add a new line to my account and, obviously, a new phone for that line.
My questions are
1: Can I use that positive Tab balance towards the cost of the new phone for the new line?
And 2: Regardless of the new line or phone, if I switch my current plan to a new plan what happens to that positive Tab balance? Do I get a credit for it?
Thanks for any help.
