The invention relates to a method for storing and accessing useful data (48) and configuration data (62) in a mobile device (10) that is linked with a user module (12). According to a first embodiment of the invention, the at least part of the useful data (48) is stored in the mobile device (10) in encrypted form and, when the data is accessed, decrypted using a decryption function (66) of the user module (12). According to a second embodiment of the invention, the configuration data (62) is stored in the user module (12). The configuration data (62) indicates whether and to what extent an application program (46) may be executed by the mobile device (10). The invention increases security of useful data (48) and application programs (46) in the mobile device (10) and protection against unauthorized access thereto.
