Abstract

The invention discloses a hand-held electronic apparatus and a detection method for a subscriber identity module (SIM) card. The hand-held electronic apparatus comprises an antenna, the SIM card and a processor. The antenna is configured on the removable back cover of the hand-held electronic apparatus for receiving wireless signals. The processor is coupled to the SIM card and is used for detecting the signal intensity and signal variance of the wireless signals received by the antenna. If the signal intensity is smaller than a first critical value or the signal variance is greater than a second critical value, the processor polls the SIM card so as to detect whether the SIM card is already removed.

Description

technical field [0001] The invention relates to an electronic device and its detection method, and in particular to a hand-held electronic device and its user identification card detection method. Background technique [0002] Generally, in a mobile communication system, when a user applies for a mobile phone number, he will obtain a Subscriber Identity Module (SIM) card. The user identification card must be placed in the user identification card slot (socket) of the handheld electronic device. Its function is to identify legitimate users, which is an important basis for calls and billing, and can store relevant identification data of users on the communication network. That is to say, the handheld electronic device can only use the calling function if it has a subscriber identification card, and different mobile phone numbers correspond to different subscriber identification cards. Therefore, for users who have multiple SIM cards at the same time, there is often a need to ...
