As shown in fig. 1, a SIM card is composed of a large card base of ID-1 type and a small card embedded in the large card base, and the small card is provided with an IC chip module; patterns, characters and the like can be printed on the large card base and the small card according to requirements, and the names, personalized Logo (marks), card serial numbers and the like of operators are generally printed. The shape and the size of the large card base conform to the ISO7816 standard, the shape and the size of the small card, the relative position of the small card embedded into the large card base and the like conform to the GSM11.11 standard, the size of the small card is 25mm multiplied by 15mm multiplied by 0.76mm, the distance between the left edge of the small card and the left edge of the large card base is 6.25mm, and the distance between the upper edge of the small card and the upper edge of the large card base is 16.48 mm. The IC chip module mainly stores parameter information such as user identification information, authentication information, preferred network standards and frequency bands, home zone identification and the like, wherein the user identification information is mainly embodied as IMSI (international mobile subscriber identity), the IMSI comprises MCC (mobile country code), MNC (mobile network code) and MSISDN (Mobile station International ISDN number; ISDN: Integrated services digital network, Integrated services digital network), the MCC is used for identifying the home country of the mobile subscriber, the MNC is used for identifying the home network of the mobile subscriber, and the MCC and the MNC form a PLMN (public land Mobile network) value of a home network operator; the MSISDN, which is used to identify different mobile subscribers within a PLMN service area, consists of HLRID (home location register identifier) and subscriber number in HLR (home location register). If a user needs to use a GSM network to develop a mobile communication service, an SIM card must be inserted into a mobile terminal (generally, a mobile phone) for the GSM network to perform identity authentication, voice information encryption, and the like for the user. The user can purchase the SIM card through the SIM card selling point of the mobile operator, and the SIM card purchased by the user is shown in fig. 1.
