Hi. I have nextel phone and services but my phone has been acting up and i really want to replace it. The problem is that I have not had the phone/servie long enough to qualify for the upgrage through Nextel and hence will have to pay full price for a new phone. I really want to avoid spending 300 bucks for a cell phone. Does anyone know if I can purchase a boost mobile pre-pay phone and put my nextel sim card it it? Or does anyone know of any reputable places that i can get a desent nextel phone for a decent price? Thanks!
