Abstract
A method and apparatus for providing a mobile station user with information about anticipated roaming charges. The visitor communication system transmits a graded roaming signal to the mobile station user indicative of the anticipated roaming costs. The graded roaming signal is determined by contractual agreements between the visitor communication system provider and user's service provider. This information is stored in a data base at the user's home communication system and is provided to the visitor communication system upon request for authorization to provide service. The graded roaming signal is broadcast to the mobile station and displayed to allow the mobile station user to estimate the cost of the service being provided.
