Disable SIM Card Security
If you no longer need SIM card security, you can disable it.
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
54).
To disable SIM card security:
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.
