Problems solved by technology

[0003] For the convenience of users, current mobile terminals support dual SIM cards, and even three SIM cards and four SIM cards work at the same time. However, since each SIM card uses an independent physical interface in the mobile terminal, processing The number of pins used for SIM card detection in the device needs to be determined by the number of SIM cards inserted into the mobile terminal, that is, how many SIM card applications the mobile terminal supports, and accordingly its processor needs to allocate how many SIM cards in principle. One pin is used for the detection of the SIM card, so too many pins need to be configured in the mobile terminal for the detection of the SIM card, resulting in a waste of pin resources

Abstract

The invention discloses an SIM card detection method, electronic equipment and a computer storage medium. The detection method comprises the steps that an input and output port pin of a processor is connected with an output pin of an SIM card module, at least one SIM card is currently contained in the SIM card module, and each SIM card has a unique identification number; the processor receives thecharacteristic information of the serial number sent by the SIM card module through an input / output port pin of the processor, and the serial number comprises an identification serial number of the SIM card; and the level state on the pins of the input / output port is detected to identify the serial number, thereby determining the in-place state of each SIM card currently accommodated in the SIM card module. In this way, one input / output port pin in the host processor is connected with the output pin of the SIM card module inserted into the host, so that the host supports the application of aplurality of SIM cards, the pin resources of the host processor are saved, the detection speed of the SIM cards is improved, and the expandability is relatively high.

Description

technical field [0001] The present application relates to the technical field of SIM card detection, in particular to a SIM card detection method, electronic equipment and computer storage medium. Background technique [0002] Now, SIM (Subscriber Identity Module, Customer Identification Module) card pluggable detection technology has been widely used in various mobile terminals, and various SIM cards can be compatible with each other in mobile terminals, put the SIM card into any It can be effectively used in mobile terminals with card interface. [0003] For the convenience of users, current mobile terminals support dual SIM cards, and even three SIM cards and four SIM cards work at the same time. However, since each SIM card uses an independent physical interface in the mobile terminal, processing The number of pins used for SIM card detection in the device needs to be determined by the number of SIM cards inserted into the mobile terminal, that is, how many SIM card app...
