Abstract

The application discloses a method for recovering lost SIM cards of electronic equipment. The method includes: firstly, the electronic device recognizes a scenario where card saving is required, where card saving refers to whether to power on the SIM card. Start a configurable timer according to the card rescue scenario. The electronic device periodically obtains the power-on information for powering on the SIM card according to the time set by the timer; the electronic device judges whether the power-on condition needs to be given to the SIM according to the obtained power-on information; if the power-on condition information is met, the electronic device Power on the SIM card. When the SIM card is lost, the method can recover the lost SIM card more accurately and in a timely manner.

Description

technical field [0001] The present application relates to electronic technology, and in particular to a method for restoring a lost SIM card of an electronic device and the electronic device. Background technique [0002] At present, electronic devices generally support the hot swap function of the SIM card. Hot-swapping means that the user does not need to shut down the electronic device when inserting or removing the SIM card, then remove the card, insert the card, and finally turn on the electronic device. The user can pull out or insert the SIM card when the electronic device is turned on. When the user hot-plugs the SIM card, the level of the interrupt PIN in the SIM card holder at the SIM card interface in the electronic device will change. The electronic device supplies power to the SIM card according to the level state of the interrupt PIN. [0003] However, when the interrupt PIN is abnormal, the electronic device will not supply power to the SIM card when the SI...
