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.
Note: 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.
The following sections provide information about managing SIM card security:

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 46).
