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.
