Unblock the SIM Card With a PUK
Before you start the following procedure, contact your mobile service provider to receive
a PIN unlock key (PUK) that lets you unblock the SIM card.
WARNING:
Be careful entering the PUK multiple times because you can enter only a
limited number of incorrect PUKs. The number of allowed attempts depends on the
SIM card. If you run out of available attempts, you might need to contact your mobile
broadband service provider again.
To unblock the SIM card with a PUK:
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.
The Alerts section of the Dashboard page displays a message about the SIM card
being blocked and a link to a pop-up window.
5. Click the link.
