Communication method in mobile telephone systems and the subscriber identity module

Communication method in the mobile telephone systems, preferably in the telephone system of the GSM type, in which the subscriber identity module is allocated at least two identity functions (IMSI 1, IMSI 2), which are activated by the user. The proposed example of using the subscriber identity module is carried out by the working printed circuit board, which can be fixed in two different positions, suitable for both identity functions accordingly. Preferably these positions are correspondingly determined by the one or the other end of the printed circuit board.Claims: 15Fig.: 6
