Will there be any extra charges if I pay off my iphone 6 Next plan and sign up for a new next plan for the Iphone 6s?
Currently I have the iphone 6 on the Next 18 plan. I have $374 payments left (half left). If I pay off my current plan, sell my iphone 6 to someone for $450, and get the Iphone 6s on a new Next 18 plan, will there be any extra charges besides the $15 activtion fee?
