SIM card security
To manage your SIM card
Most SIM cards are locked at the time of purchase.
If the SIM card lock is on, you have to enter your
PIN (Personal Identity Number) the first time you use
your FCT. See Enter PIN on page 11.
Note: once you have entered the PIN code for the
first time you will not have to enter it again unless
you change your SIM card. The FCT performs this
operation automatically in case of power failure.
If you enter your PIN incorrectly three times in a
row, the SIM card will be blocked.
Note: if you have the DA20 accessory display
(See “Accessories” on page 39), an “ENTER PUK”
message will show on your display indicating that
your SIM card is blocked.
To unblock your SIM card
To unblock your SIM card, you need to enter your
PUK (Personal Unblocking Key), which is supplied
by your network operator.
The procedure to enter the PUK is exactly the same
as for entering the PIN.
Note: if you enter the wrong PUK ten times in a row,
your card will be permanently blocked. If this
happens, you should contact your network operator.
To change your PIN
Your can change the PIN in the SIM card by dialing
from the fixed line telephone connected to the FCT
the following sequence:
**04*OLD_PIN*NEW_PIN*NEW_PIN#
