摘要： A network access card switching method is performed by an electronic device on which a first network access card and a second network access card are installed. The first network access card is a default network access card of the electronic device. The network access card switching method includes determining that a user enables an intelligent network access card switching function, activating the first network access card, transmitting the data service using the first network access card, monitoring a network state of the first network access card in real time, and when determining that the network state of the first network access card meets a first preset condition, disconnecting the data service transmitted using the first network access card, activating the second network access card, and transmitting the data service by using the second network access card.

摘要： 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.

摘要： A network access card switching method is performed by an electronic device on which a first network access card and a second network access card are installed. The first network access card is a default network access card of the electronic device. The network access card switching method includes determining that a user enables an intelligent network access card switching function, activating, by the electronic device, the first network access card, transmitting the data service using the first network access card, monitoring a network state of the first network access card in real time, and when determining that the network state of the first network access card meets a first preset condition, disconnecting the data service transmitted using the first network access card, activating the second network access card, and transmitting the data service by using the second network access card.

摘要： This application provides a method and an apparatus for verifying a personal identification number PIN code. When a first SIM card is inserted into a powered-on terminal device or the terminal device into which the first SIM card is inserted is powered on, whether a mapping relationship includes a PIN code to which a first ICCID of the first SIM card is mapped is queried; the PIN code is sent to the first SIM card if the mapping relationship includes the PIN code to which the first ICCID is mapped; and a verification result of the PIN code from the first SIM card is received.
