The monthly fee for NEXT is just your installment for the device. It would be no different compared to buying outright with, say, a credit card and just paying a little bit every month except with the credit card, you might have to pay interest. As far as I'm aware, it's only T-Mobile's JUMP program that has a monthly fee.I guess it just depends if you are on a family plan or individual. Next also has a monthly fee in addition to the phone price.
