Abstract: A system and various methods for provisioning service zones is disclosed. Service zones establish a billing or usage rate for a particular mobile or cellular number. Multiple service zones may be utilized in relation to any one mobile number. One aspect relates to allowing the service subscriber to enter service zone information. Another aspect relates to electronically displaying service zone information to the service provider and/or the subscriber, such as by storing service zone information on a server which may be accessed over the Internet by an appropriate computer. Yet another aspect relates to displaying physical location information of a mobile communications unit at the time of a particular call, and presenting this physical location information on an electronic geographical map which also preferably depicts related service zone information.
