Figure 4.5 shows the SIM page requiring the unlock code to be entered. At this point the user has 10
attempts to enter the correct unlock code or the SIM card will be rendered unusable.
PIN security options
After PIN security has been enabled, the SIM page will display three options for changing the PIN
functionality, Remember PIN, Disable PIN, or Change PIN. Only one of these options can be
changed and saved at a time.
Remember PIN
Selecting YES will allow the modem to remember the security PIN making it unnecessary to
enter the PIN each time the modem tries to connect to the network. Selecting NO will set the
modem to not remember the current PIN, requiring the user to enter the PIN when requested.
Since only the modem remembers the PIN, using the SIM card in a different modem will require
PIN authorization to dial out.
Disable PIN
Selecting YES will disable the PIN security feature; the current PIN will need to be entered to
allow disabling. A selection of NO indicates that PIN security is enabled.
Change PIN
Selecting YES will allow the user to change the current PIN to a new one. Selecting NO will not
require the user to change the PIN in the New PIN and Confirm PIN fields. When changing PINs,
the user is required to input the current PIN, the new PIN, and the new PIN again in the fields
provided.
After one of the options is changed, click the SAVE button to refresh the page showing the
changes.
