Abstract: The invention relates to a method for the use of a portable radio telephone, which has a processor (4) controlling and supervising the operation, a keyboard (7) and a display (6), and a card reader (3), in which case, when the radio telephone is being used, the user identification data required by the radio telephone system are read from the card (1). The identification data (21) of the card (1) of the user authorized to use the radio telephone concerned are recorded in the non-erasable memory (5) of the processor (4), whereupon the radio telephone shifts into a mode locked to this card in such a way that its use is possible with only a certain card (1). By means of this method, protection is achieved against unauthorized use of the radio telephone.
