Figure 19 - SIM Security - SIM PUK Needed
Remember PIN
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 entered by the user when they set the “Remember PIN” feature is encrypted and stored locally in 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, the PIN must be manually entered via the router‘s configuration interface. This is clearly not desirable where the router is unattended.
