Configuring PIN Management

Configuring PIN Management

Context

A personal identification number (PIN) is a password used to control the rights of using a USIM or SIM card, and prevents unauthorized users from using the USIM or SIM card.

NOTE:

A PIN is a decimal integer of 4 to 8 digits. Obtain the initial PIN from the carrier.

Procedure

  • Enable PIN authentication.

    PIN authentication on a 3G modem prevents unauthorized users from using a USIM or SIM card. After PIN authentication is enabled, the device will authenticate the PIN each time when the USIM or SIM card is started. To use the 3G modem, you must enter the correct PIN to unlock the USIM or SIM card.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The 3G cellular interface view is displayed.

    3. Run pin verification enable [ auto ]

      PIN authentication is enabled.

      By default, PIN authentication is disabled.

      In this step, you must enter a PIN to enable PIN authentication for the 3G data card.

    4. Run pin verify [ auto ]

      The device is configured to authenticate a PIN.

      In this step, after the PIN is entered manually or automatically, wait for a period of time. When the system displays the message "PIN has been verified successfully.", PIN authentication is successful.

  • Change a PIN.

    Periodically changing a PIN can improve security of the USIM or SIM card.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The 3G cellular interface view is displayed.

    3. Run pin verification enable [ auto ]

      PIN authentication is enabled.

      By default, PIN authentication is disabled.

      In this step, you must enter a PIN to enable PIN authentication for the 3G data card.

    4. Run pin modify

      The PIN of the USIM or SIM card is changed.

      In this step, you need to enter the old PIN and a new PIN, and then enter the new PIN again to verify the new PIN. When the system displays the message "PIN has been changed successfully.", the PIN has been changed.

  • Unlock the USIM or SIM card using the personal identification number unlocked key (PUK).

    If a user enters an incorrect PIN for three consecutive times, the USIM or SIM card is locked. To unlock the USIM or SIM card, enter a PUK.

    NOTE:

    PUKs are provided by the carrier. If a user enters incorrect PUKs for 10 consecutive times, the USIM or SIM card is permanently locked, and the user needs to obtain a new one from the carrier.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The 3G cellular interface view is displayed.

    3. Run pin verification enable [ auto ]

      PIN authentication is enabled.

      By default, PIN authentication is disabled.

      In this step, you must enter a PIN to enable PIN authentication for the 3G data card.

    4. Run pin unlock

      The USIM or SIM card is unlocked using the PUK.

      In this step, you need to enter the old PIN and a new PIN, and then enter the new PIN again to verify the new PIN. When the system displays the message "Warning: PIN will be unlocked and changed. Continue? [Y/N]", select Y and wait for a period of time. When the system displays the message "PIN has been unlocked and changed successfully.", the USIM or SIM card has been unlocked.
