Abstract

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.

First claim

What is claimed is:

1 . A method, applied to a terminal device, the method comprising:
receiving a first operation of a user, wherein the first operation instructs the terminal device to enable a function of automatically verifying a personal identification number (PIN) code of a first subscriber identity module (SIM) card; after the receiving the first operation and based on that no lock screen password is set for the terminal device:
displaying a first prompt for the user to enter a lock screen password,
receiving the lock screen password entered by the user,
displaying a second prompt for the user to enter a first PIN code, the second prompt being different from the first prompt, and
receiving the first PIN code entered by the user;
storing the first PIN code to complete enabling the function of automatically verifying the PIN code of the first SIM card, wherein when the function of automatically verifying the PIN code of the first SIM card is enabled and the first PIN code is stored, the terminal device uses the first PIN code to automatically verify the first SIM card; and after the storing, verifying the PIN code of the first SIM card using the first PIN code without the user inputting the PIN code when the first SIM card is inserted into the terminal device and the terminal device is in a powered-on state, or when the terminal device into which the first SIM card is inserted is powered on.

2 . The method according to claim 1 , wherein the terminal device further stores a second PIN code of a second SIM card, a second function of automatically verifying the second PIN code of the second SIM card is enabled, and the method further comprises:
verifying the second PIN code of the second SIM card without the user inputting the second PIN code in response to detecting the second SIM card is inserted in the terminal device.

3 . The method according to claim 1 , wherein automatically the verifying the PIN code of the first SIM card comprises:
verifying the PIN code of the first SIM card when the function of automatically verifying the PIN code of the first SIM card is enabled.

4 . The method according to claim 1 , wherein the receiving the first PIN code entered by the user, and storing the first PIN code comprises:
receiving a second PIN code entered by the user; displaying a third interface when the second PIN code entered by the user is an initial PIN code of the first SIM card, wherein the third interface prompts the user to enter a new PIN code; and receiving the new PIN code entered by the user as the first PIN code, and storing the first PIN code.

5 . The method according to claim 1 , wherein the receiving the first PIN code entered by the user, and storing the first PIN code comprises:
receiving a second PIN code entered by the user; and when the second PIN code entered by the user is different from an initial PIN code of the first SIM card, using the second PIN code entered by the user as the first PIN code, and storing the first PIN code.

6 . The method according to claim 1 , wherein after the verifying the PIN code of the first SIM card, the method further comprises:
displaying a fourth interface, wherein the fourth interface prompts that PIN code verification of the first SIM card succeeds.

7 . The method according to claim 6 , wherein before the verifying the PIN code of the first SIM card, the method further comprises:
displaying a fifth interface, wherein the fifth interface prompts to enter the lock screen password; and switching to an unlocked state when receiving a correct lock screen password.

8 . The method according to claim 1 further comprising:
receiving a second operation of the user, wherein the second operation instructs the terminal device to display the PIN code of the first SIM card;
displaying a sixth interface, wherein the sixth interface prompts to enter verification information; and
receiving the verification information, and outputting a fourth PIN code, wherein the fourth PIN code is the PIN code of the first SIM card.

9 . The method according to claim 1 , further comprising:
storing an integrated circuit card identifier (ICCID) of the first SIM card.

10 . The method according to claim 9 , wherein the ICCID corresponds to the first PIN code.

11 . The method according to claim 1 , wherein the terminal device does not store a PIN code of a second SIM card, and the method further comprises:
displaying a seventh interface in response to detecting the second SIM card is inserted, wherein the seventh interface prompts to enter the PIN code of the second SIM card.

12 . The method according to claim 11 , further comprising:
displaying an eighth interface when the terminal device has set the lock screen password in response to the first operation, wherein the eighth interface prompts to enter the lock screen password.

13 . The method according to claim 11 , wherein the verifying the PIN code of the first SIM card comprises:
querying whether the terminal device comprises a PIN code corresponding to an integrated circuit card identifier (ICCID) of the first SIM card; sending the PIN code corresponding to the ICCID of the first SIM card to the first SIM card when the terminal device comprises the PIN code corresponding to the ICCID of the first SIM card; and receiving a verification result obtained from the first SIM card for the PIN code corresponding to the ICCID of the first SIM card.

14 . The method according to claim 11 , further comprising:
outputting first prompt information when the function of automatically verifying the PIN code of the first SIM is not enabled, wherein the first prompt information prompts to enable the function of automatically verifying the PIN code of the first SIM card.

15 . A terminal device, comprising:
one or more processors; and a non-transitory memory configured to store processor-executable instructions, wherein when executing the processor-executable instructions, the one or more processors are configured to perform operations comprising:
receiving a first operation of a user, wherein the first operation instructs the terminal device to enable a function of automatically verifying a personal identification number (PIN) code of a first subscriber identity module (SIM) card;
after the receiving the first operation and based on that no lock screen password is set for the terminal device:
displaying a first prompt for the user to enter a lock screen password,
receiving the lock screen password entered by the user,
displaying a second prompt for the user to enter a first PIN code, the second prompt being different from the first prompt, and
receiving the first PIN code entered by the user;

storing the first PIN code to complete enabling the function of automatically verifying the PIN code of the first SIM card, wherein when the function of automatically verifying the PIN code of the first SIM card is enabled and the first PIN code is stored, the terminal device uses the first PIN code to automatically verify the first SIM card; and
after the storing, verifying the PIN code of the first SIM card using the first PIN code without the user inputting the PIN code when the first SIM card is inserted into the terminal device and the terminal device is in a powered-on state, or when the terminal device into which the first SIM card is inserted is powered on.

16 . The terminal device according to claim 15 , wherein the terminal device further stores a second PIN code of a second SIM card, a second function of automatically verifying the second PIN code of the
