There is so much info about these it a wonder that iv never even knew what they were. I have seen them before but have never new all this info was out there.
btw whats stoping someone from copy cards like they copy CDs or anything else in the world were not supposed to be copying. It seams that if we wanted to we could buy a blank are and write bogus info which would allow us to use an unlimited amount of a gms modem for free
