The SIM card is a kind of subscriber identity card. The SIM card includes an IMSI (International Mobile Subscriber Identity), a key and a security algorithm of the Mobile Subscriber, a memory space available for the Mobile Subscriber, and the like. IMSI can be used to distinguish mobile subscribers in a cellular network. The IMSI is a non-repeating identity in all cellular networks. The IMSI is composed of a string of decimal digits with a maximum length of 15 digits. The IMSI is formed by sequentially connecting MCC (Mobile Country Code), MNC (Mobile Network Code), and MSIN (Mobile subscriber identity Number). The MCC may uniquely identify the country to which the mobile subscriber belongs, and is 3 digits in length. The MNC may be used to distinguish the mobile network to which the mobile subscriber belongs, and the length of the MNC may be determined by the value of the MCC, and may be 2 digits (european standard) or 3 digits (north american standard).

The MCC MNC corresponding to golombia Movistar (spanish telecom carrier) includes 732 123. The operator identifier is an identifier for uniquely identifying the mobile network operator, and may specifically include a character string of at least one character of letters, numbers and symbols.
