connected to the modem are disconnected when the modem resets. No services or applications are

Manage SIM Card Security
You can create another level of security by establishing a PIN that you must enter before modem can access
the mobile broadband connection and before you can make changes to the mobile broadband connection.
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.

Enable SIM Card Security
Before you can use the PIN to enable SIM card security, you must obtain the default SIM PIN from your
mobile broadband service provider. If you do not know your SIM PIN or your SIM card did not come with a
PIN, you can try any of the following PINs:
•
0000
•
1111
•
1234
•
Last four digits of the phone number that is associated with the SIM card
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).
