ABSTRACT:
A mobile subscriber enters a service code followed by a called party number. An application module associated with a mobile station stores the received called party number at an attached Subscriber Identity Module (SIM) card. After determining that the mobile station has traveled into the designated home zone, the application module retrieves the stored called party number and automatically originates an outgoing call towards the called party number. By waiting until the mobile station has entered the home zone, the resulting call connection avoids additional air time charges.
