A method for starting up a mobile terminal in flight mode according to the present invention, as shown in Figure 1, comprises steps:

S100: When the smart mobile terminal is turned on in flight mode, its internal power supply stabilizes the power supply voltage within a delay time of 2 seconds, and outputs an activation voltage signal to the SIM card.

Specifically, when the smart mobile terminal is turned on in flight mode, it extracts a power control command from its internal memory to its internal command register, calls the control command, and sends a pulse signal to the pulse counter. In order to ensure the accuracy of the counting pulses of the pulse counter, the pulse signal is a high-level signal. In order to ensure that no current higher than 2A will appear instantaneously when starting up, set the high-level signal of the pulse counter counting pulse to 2 seconds, 2 seconds Afterwards, the power supply completes voltage stabilization processing to provide a stable power supply voltage to the mobile terminal.

Specifically, the mobile terminal extracts the receiving instruction from its internal memory to its internal instruction register, and invokes the instruction, sends a receiving control signal to the SIM card, and controls the SIM receiving event. After receiving the event, the SIM card sends the event to a specified address inside the mobile terminal for temporary storage. At the same time, the central processing unit extracts the shielding control instruction from its internal memory to its internal instruction register, and calls the shielding control instruction to the external storage of the mobile terminal, sends the shielding control signal to the SIM card, controls the mobile terminal not to send signals externally, and shields the SIM card.
