The invention implies a possibility to differentiate the services a mobile telephone subscriber has access to in a cellular mobile telephone network. The functionality can be differentiated both in time and space. The subscriber is by the invention given specific functionality in a geographical limited area (20). The subscriber can for instance have full access to the mobile telephone network when he/she uses the mobile telephone within a certain area (20), whereas outside this area (21) he/she is only given a certain functionality, no functionality, or full functionality but at another price rate. There is also possibility to identify several areas with differentiated functionality. In the same way the subscriber can be given specific functionality at certain times during the 24-hour period, or during certain days. By means of SIM Application Toolkit the whole functional differentiation can be managed from the SIM-card (1). The subscriber's functional differentiation can in a simple way be changed because the list over allowed/wanted areas exists in the SIM-card and can be updated via data message (3).
