SIM security settings
The SIM security settings page can be used for authenticating SIM cards that have been configured with a security PIN.
Unlocking a PIN locked SIM
If the SIM card is locked, you will receive a notice when you access the Status page after which you will be directed to the PIN
settings page to enter the PIN. The PIN settings page lists the status of the SIM at the top of the page.
If you are not redirected to the PIN settings page, to unlock the SIM:
a) Click on the Networking menu from the top menu bar, and then click SIM security settings.

b) Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN.
c) If you are placing the router in a remote, unattended location, you may wish to check the Remember PIN option. This
feature allows the router to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up).
This enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the
router to connect to the cellular service.
When this feature is enabled, the PIN you enter when setting the
Remember PIN feature is encrypted and stored
locally on the router. The next time the SIM asks the router for the PIN, the router decrypts the PIN and automatically
sends it to the SIM without user intervention.
When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the router‘s
configuration interface. In situations where the router will be unattended, this is not desirable.
Note: Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted.
d) Click the Save button. If successful, the router displays the following screen:
Enabling/Disabling SIM PIN protection
The security PIN protection can be turned on or off using the PIN protection toggle key.
