Abstract: A subscriber identification module (SIM) card detection failure recovery method for an electronic device includes that the electronic device identifies a card recovery scenario, where card recovery includes whether to power on a SIM card. A configurable timer is started based on the card recovery scenario. The electronic device periodically obtains, based on a time set by the timer, power-on information for powering on the SIM card. The electronic device determines a power-on condition of the SIM card based on the power-on information. If the power-on condition is met, the electronic device powers on the SIM card.

Abstract: In accordance with an embodiment, a method for verifying a personal identification number (PIN) code includes: receiving a first PIN code entered by the user, and storing the first PIN code to complete enabling the function of automatically verifying the PIN code of a first subscriber identity module (SIM) card, wherein the first PIN code is used by a terminal device to automatically verify the first SIM card; and verifying automatically the PIN code of the first SIM card in response to the first SIM card being inserted into the terminal device while the terminal device is powered-on or in response to the terminal device into which the first SIM card is inserted being powered-on.
