Abstract

The present invention discloses a SIM substitution method, device and system, and belongs to the mobile phone design field. The SIM substitution method comprises the steps of connecting a mobile device, after connecting the mobile device successfully, receiving an obtaining request sent by the mobile device and used for requiring to obtain the information of a SIM; utilizing a communication converter to read the information of the SIM; utilizing the communication converter to send the read information of the SIM to the mobile device. The SIM is arranged inside an external device independently, by the information conversion, the information of the SIM is read to an information memory of the SIM, and in the mobile device, the information memory of the SIM substitutes for the SIM and a SIM card slot, thereby solving the problem that the SIM occupies the area of an arrangement board, and realizing the effects of reducing the PCB area of a mobile phone mainboard, and being convenient to replace cards.

Description

technical field [0001] The disclosure relates to the field of mobile phone design, in particular to a SIM card replacement method, device and system for a customer identification module. Background technique [0002] The SIM card slot where the SIM (full name: Subscriber Identity Module, Chinese: Customer Identification Module) card in the smart phone needs to occupy a certain layout area, which leads to an increasingly tight layout area of ​​the mobile phone motherboard. [0003] In order to reduce the occupation of the layout area by the SIM card, operators currently program the mobile phone number directly into the mobile phone. This method of directly programming the mobile phone number in the mobile phone will cause a mobile phone to be bound to a programmed mobile phone number. If you need to change the mobile phone number, you need to reprogram it through the operator, which makes it difficult to change the mobile phone number. . Contents of the invention [0004]...
