Configuring PIN Management

Configuring PIN Management

The personal identification number (PIN) of a SIM card ensures security of the SIM card.

Context

A PIN identifies the user of the SIM card and prevents unauthorized access to the SIM card.

If a user enters incorrect PINs three consecutive times, the PIN is locked to protect security of the SIM card. To unlock the PIN, enter the PIN unblocking key (PUK).

NOTE:

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

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

Procedure

  • Enabling PIN authentication

    PIN authentication prevents unauthorized users from using a SIM card. A user can use an LTE modem only after the PIN is authenticated. If PIN authentication is disabled, anyone can use the SIM card.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run pin verification enable [ auto ]

      PIN authentication is enabled for an LTE modem.

      By default, PIN authentication is disabled.

      In this step, you must enter a PIN to enable PIN authentication for the LTE modem.

  • Authenticating a PIN

    After PIN authentication is enabled for an LTE modem, the PIN must be authenticated every time you start the SIM card. If PIN authentication fails, the LTE modem cannot provide data communication functions.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run pin verify [ auto ]

      The PIN is authenticated.

      In this step, you must enter the PIN. When the message "PIN has been verified successfully." is displayed, the PIN has been authenticated.

  • Changing a PIN

    After PIN authentication is enabled, you are advised to change the PIN periodically to improve the SIM card security.

    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run pin modify

      The PIN is changed.

      In this step, you must enter the old PIN and enter a new PIN twice. When the message "PIN has been changed successfully." is displayed, the PIN has been changed.

  • Using the PUK to unlock a SIM card
    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run pin unlock

      The PUK is configured to unlock the SIM card.

      In this step, you must enter the PUK and enter a new PIN twice. When the message "Warning: PIN will be unlocked and changed. Continue? [Y/N]:" is displayed, enter Y. When the message "PIN has been unlocked and changed successfully." is displayed, the SIM card has been unlocked.

Verifying the Configuration

  • Run the display cellular interface-number { all | hardware | security | network | profile | radio } command to check information about all call sessions on the LTE modem.
