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.
