Abstract

The invention discloses a device for realization of reading and writing of an SIM (subscriber identity module) card, which is used for realizing reading and writing of the SIM card in a wireless manner. The device comprises a Bluetooth module, a micro control unit, an intelligent card interface and a power supply management module; the intelligent card interface is used for insertion of the SIM card; the micro control unit is used for receiving card reading commands transmitted by a mobile terminal via the Bluetooth module after insertion of the SIM card, reading the ICCID (integrated circuit card identity) number of the SIM card according to the card reading commands, transmitting the ICCID number to the mobile terminal through the Bluetooth module, receiving card writing commands transmitted by the mobile terminal through the Bluetooth module after an IMSI (international mobile subscriber identity) number corresponding to a short message center number, a mobile phone number of a user and the ICCID number is obtained by the mobile terminal, writing in the IMSI number, the short message center number and the mobile phone number of the user according to the card writing commands; and the power supply management module is used for supplying power to the Bluetooth module and the micro control unit. The invention also discloses a system and a method for realization of reading and writing of the SIM card.

Description

technical field [0001] The invention relates to the communication field, in particular to a device, system and method for realizing reading and writing of SIM cards. Background technique [0002] SIM card (Subscriber Identity Module, customer identification module), also known as smart card, subscriber identity card, digital mobile phone must be equipped with this card before it can be used. At present, when making a SIM card, the IMSI code (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) is generally solidified in the SIM card of the mobile phone and bound to the phone number, and the SIM card activation operation is performed when the user makes a call for the first time. The limitation of this kind of SIM card is that after the mobile phone number is bound with the SIM card, the user can no longer choose independently. In order to improve the problem that the user cannot choose the mobile phone number independ...
