So, you get a new device and sign up with jump. You purchase a $600 phone through EIP, and pay monthly $25 on that. 6 months later and you go to upgrade, you've payed $150 out of $600. If you trade in that device, what happens to the remained of that balance, $450? The way I am reading the plan is that by trading in your phone, the remaining EIP balance is taken care of, so that $450 you would not be required to pay when you upgrade. Is this correct, or do they take out the trade in value of your phone at the time, and you still have to pay what is left?
So say the phone trade in value is $200, then you would still have to pay $250, and they tack your new phone cost on top of this $250, so if you get a new phone for $600, you would owe $850 and pay this monthly. Just wanted to make sure to clarify this, because it makes a very big difference.
