Answer 1 :
yea nextel works every wear i dont have a prepaid plan but i know that they still have one
Answer 2 :
You need to contact Cingular and find out why it is not working. "Did you buy your phone card?" That has to be purchased first in order for your phone to work. You will have to put in codes, if its a prepaid phone. Unless they bill you.. Try that first before you go out and buy another one. Good Luck!
Answer 3 :
you should do as Sue said first, and before you get Nextel, make sure that the prepaid service they offer (Boost) will work there. Although Nextel works there, it's not Nextel's system that you're actually using, it's a company they have a deal with.
