Degradation of user convenience in regard to service provision in mobile data communications is prevented even in cases such as where a mobile communications terminal of a different system has been adopted in order to receive roaming service. A service control system comprises a contract content database which stores the content of a mobile data communications contract corresponding to a mobile communications terminal; a roaming determining part for determining whether or not the connection from the mobile communications terminal to the mobile data communications network (home network) is by means of roaming; and a service deciding part which, in the case that it has been determined by the roaming determining part that the connection is by means of roaming, refers to the contract content corresponding to the mobile communications terminal connected to the home network, the content of which is stored in the contract content database, and decides on the service for mobile data communications with the mobile communications terminal.
