To enable SIM card security:
1.
Launch a web browser from a device that is connected to the modem.

connected to the modem.
2.
In the address field of your browser, enter http://192.168.5.1.
The limited Dashboard page displays.

If you did not select the Remember me check box when you logged in previously, enter the modem
password in the Sign In field.
See the modem label for the default password.
4.
Click the Sign In button.
The full Dashboard page displays.
5.
Select Settings > Mobile > SIM Security.
The page displays the SIM security options.

The Submit button displays after you enter the PIN.
You are allowed only a limited number of attempts to enter the correct PIN. The number of allowed
attempts depends on the SIM card. If you run out of available attempts, the SIM card is blocked. If the
SIM card is blocked, contact your mobile broadband service provider to receive a PIN unlock key (PUK)
to unblock the PIN.

Your settings are saved. Now, when you turn on the modem, you must enter the SIM PIN before the
modem can access the mobile broadband network.
