I want to sell my iphone6+ I just unlocked it through ATT's website but I still owe about 6-7 payments on NEXT. Am I okay to sell it? I will continue to pay my monthly payment for the financing but how does it work since my phone is unlocked? Been trying to find answers everywhere but can't seem to find anything similar to my situation. Can I still cancel the data/minutes/texting portion and just pay the actual iphone6+ financing part?
