Internet
If you enable SIM card security, you must enter the SIM PIN each time that you turn on the modem before
the modem can access the mobile broadband network.
WARNING:
Be careful entering the SIM PIN multiple times because you can enter only a
limited number of incorrect PINs before the SIM card is blocked.The number
of allowed attempts depends on the SIM card. If the SIM card is blocked, you
must obtain a PIN unlock key (PUK) from your mobile broadband service
provider to unblock the PIN (see Unblock the SIM Card With a PUK on page
54).
To enter the SIM PIN:
1. Launch a web browser from a device that is connected to the modem.
The device can be a computer that is directly connected to the modem or a client from a router that is
connected to the modem.
2. In the address field of your browser, enter http://192.168.5.1.
The limited Dashboard page displays.
3. 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.
