Document Type and Number:
Japanese Patent JP3472309
Kind Code:
B2
Abstract:
The invention pertains to a method for crediting or recrediting a SIM card (subscriber identity module) for a mobile radio telephone (6) with a given amount (28). The SIM card comprises a chip provided with a memory element (11). The amount is stored in said memory element (11) and decreases as the mobile radio telephone is used. In order to credit or recredit a SIM card, the user must possess a memory board (13) payable in advance. The memory board (12) has a code area (14) covered with a nontransparent detachable film (22). A code (15) appears upon detaching the film (22). The SIM card (7) and memory board (13) holder dials a service number from a telephone (6, 8), the calling party thereby being connected to a data bank (17) where all codes allocated to memory boards (15) and the corresponding amounts (12) are recorded. The calling party is requested to input his code number into the telephone (6, 8) with which he is calling. Once entered, the code is compared with the code recorded at the data bank. As soon as the code (15) has been retrieved, a short message with the amount to be credited or recredited is temporarily recorded at the short message service center (18, 19). The amount (28) and the code (15) registered at the data bank (17) are then marked as depleted or erased. Next time the holder inserts his SIM card (7) into any mobile radio telephone and sets up a connection with the telecommunication network (9), said card will be credited or recredited with the amount (28) temporarily recorded on the basis of the prepared short message (20).
