The operation of a blue box was simple: First, the user placed a long distance telephone call, often to a number that was in the target area. Usually, this initial call would be to a 1-800 number or some other non-supervising telephone number like directory assistance.
Furthermore, does the blue box still work? The Blue Box no longer works in most Western nations, as modern switching systems are now digital and do not use in-band signaling.
