ABSTRACT:
A mobile station is provided comprising a transmission and reception unit and an identification module that can be inserted into the mobile station. The mobile station provides a user, in the standby mode, with services and/or data records that can be retrieved by the user. To prevent unauthorized access to the services and/or data records, each service and/or data record is assigned a characteristic access identifier that is activated or deactivated by inputting and/or transmitting an associated security code. For the purpose of inputting and/or transmitting the security code, the mobile station comprises a security component. Depending on the state of the access identifier, whether activated or deactivated, access to a service and/or data record in the standby mode on the mobile station is disabled or enabled, respectively.
