I couldn't find a direct answer elsewhere. Me and my wife preordered and received our note 9s direct from Samsung. They offered a better trade in deal. I'm trading in my S8 plus, shes trading her v20. We still owe a little bit on tmobile EIP. Terms of trade said we are responsible for any remaining payment. Of course, I'm going to pay them. But I was hoping to pay them off over course of 2 or 3 months. Do I need to pay off our remaining balance in full immediately before we send them in for trade or can I keep payments current with tmobile and just pay it off over next couple months? I'm not changing anything with my tmobile account.i called Samsung directly and they just repeated the terms ad nauseam that I'm responsible for paying any remaining payments. I dont think she understood my question.
