 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.

At this point the user has 3 attempts to enter the correct PIN. If the correct PIN is not entered after 3 attempts, an unlock
code or PIN Unblocking Key (PUK) from the service provider will be required before the SIM card is usable again. Figure 22
shows the SIM settings after an incorrect PIN has been entered.
Figure 22: SIM PIN Rejected
Figure 23 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.
