The invention can provide safety protection for application services of mobile communication terminals, such as mobile phones and the like, so that the secret information of users can not be revealed easily.

Description

technical field [0001] The invention relates to the communication field, in particular to a subscriber identification module card slot. Background technique [0002] At present, the mobile communication is developing rapidly, and the penetration rate of mobile phones is very high; at the same time, there are also many mobile communication terminals with special purposes developed based on certain special purposes. And all these devices follow certain international standards to achieve. In all these standards, most (in China, all running on the Internet) use a detachable SIM card to identify users. Correspondingly, each device has a card slot for a Subscriber Identity Module card. [0003] The Subscriber Identity Module card mentioned above is what we usually call the SIM (Subscriber Identity Module, Subscriber Identity Module) card. The SIM card is for the GSM (Global System for Mobile Communications, Global System for Mobile Communications) network. (Code Division Multip...
