They will put you on a list if you by prepaid cell phones. I got my kids two and they broke one went back for a new one and the lady that runs the store at radio shack told me if i didn't get a plan for it and new number she had to turn it in that i had 3 and one with no plan. this World has gone to hell
ps she said it really didn't have anything to do with Terrorist on the stores part it keep people from buying good cheap cell phones for 10 buck to 50 and resealing them and the list made it easier to keep you from blaming them. but in the end homeland you no who gets your name.
