Cricket does not charge any extra fees than anyone else. You have a fcc fee that is mandated by the FEDERAL goverment, local surcharged based on the city and state you live in, and local sales taxes. You are not charged for any overage on the line, the speed is simply slowed down. I wish eveyone on this site would learn the facts before they ran their mouth about something they dont seem to know anything about. Every carrier no matter who they are have a cap on their service, that is mandated in the fair use act implimented by the goverment.
