<p>The present invention relates to a SIM card personalization system, wherein the SIM card information can be replaced, at the time of the request of the subscriber, with an unoccupied IMSI in the HLR (50) to which the telephone number (MSISDN) belongs and which thus reduces the levels of SIM card stocks kept by the GSM operators and provides a more efficient, safer and faster service.</p> |
