Under normal working conditions, when the mobile phone is turned on and can be used normally, the mobile phone body will perform the following steps first. Preferably, the following steps can be performed simultaneously when the mobile phone body executes the booting program. First, the mobile phone body will record the Personal Identification Number (PIN)/PIN Unlock Key (PUK) code corresponding to the SIM card, if the mobile communication device is turned on. After the user changes the PIN code of the SIM card, the mobile phone body must re-record the reset PIN code. After the power is turned on, the mobile phone body determines whether to verify the PIN/PUK code. The PIN code is used to identify the user identity. After the user turns on the mobile phone, if the PIN/PUK code needs to be verified, the PIN code must be entered before the user can start the PIN/PUK code. After the call and the PIN code is set, the mobile phone can be prevented from being stolen.

If verification is not required, or after verification, the mobile phone body reads the original International Mobile Subscriber Identity (IMSI) Elementary File EF_IMSI to obtain the IMSI value of the SIM card. The mobile phone body and the IMSI value of the SIM card are recorded as an original IMSI value in the mobile phone body. Among them, the IMSI value records the Mobile Country Code (MCC), the Mobile Network Code (MNC) and other network related information.

Please refer to FIG. 1 , when the mobile phone body detects that the SIM card is temporarily disabled due to static electricity or poor electrical connection, or is temporarily disabled due to other external force factors, the SIM card is in an error state. , the mobile phone body will perform the following steps to restore the SIM card operation function. First, step 201 is executed to resend the last set of instructions before the SIM card error. Then, proceeding to step 203, it is determined whether the last set of instructions is resent successfully. If yes, step 207 is executed, the SIM card resumes the operation function, and the process ends; if not, step 210 is performed.

In step 210, a SIM card hot start program is executed, and a specific SIM card command program on the mobile phone body can complete the action. Then, proceed to step 212 to determine whether the hot start program is successfully executed, and if so, perform the steps. 214. In step 214, according to the setting in the mobile phone body, the PIN code is input, that is, if the SIM card in the mobile phone body needs to verify the PIN/PUK code, the PIN code is input; otherwise, no input is required, step 214 is skipped, and execution is performed. In step 216, the last set of instructions is resent again. Then, proceeding to step 218, it is determined whether the last set of instructions is resent again. If yes, proceeding to step 207, the SIM card resumes the operation function, and the flow ends. If it is determined in step 212 that the hot start program has not been successfully executed, or if it is determined in step 218 that the last set of instructions is not resent again, then step 221 is performed.

In step 221, the mobile phone body executes a SIM card cold start program, and the activate/deactivate program in the mobile phone body can complete the action. Then, proceeding to step 223, it is determined whether the SIM card cold start program is successfully executed, and if so, step 225 is performed. In step 225, according to the setting in the mobile phone body, the PIN code is input, that is, if the SIM card in the mobile phone body needs to verify the PIN/PUK code, the PIN code is required; otherwise, no input is required, and step 225 is skipped. Step 227 is performed to resend the last set of instructions a third time. Then, proceeding to step 229, it is judged whether the last retransmission of the last set of instructions is successful, and if so, the process proceeds to step 207, the SIM card resumes the operation function, and the flow ends. If it is determined in the step 223 that the SIM card cold start program is not successfully executed, or the third step of resending the last set of instructions is unsuccessful in step 229, step 230 is performed to determine whether the SIM card is removed or damaged.

In addition, in step 210 and step 221, the SIM card startup program may be an Answer To Reset (ATR) program, that is, an operation requirement parameter of the SIM card transmitted to the mobile phone body at the time of startup. If necessary To be, the mobile phone body performs a protocol and parameter selection (PPS) program, and the PPS program is a program for the mobile phone body to respond to the ATR program of the SIM card.
