SIM card
The SIM (Subscriber Identity Module) card, which
you get from your network operator, contains
information about your subscription. Always turn
off your phone and detach the charger before you
insert or remove the SIM card.
PIN code (SIM card lock)
The PIN (Personal Identification Number) code is a SIM
card lock that protects your subscription, but not the
phone itself. If the card is locked, you have to enter the
PIN code when you turn on your phone. Each PIN digit
appears as *, unless it starts with emergency number
digits, for example, 112 or 911. You can call an
emergency number without entering a PIN.
You can save contacts on the SIM card before removing
if from your phone. Contacts may also be saved in the
phone memory. See Contacts on page 17.
If you enter the wrong PIN three times in a row,
the following message appears:
PIN blocked. To
unblock, enter your PUK code provided by your
network operator.
To unblock your SIM card, see
Locks on page 34.
