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 and the battery 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. To change your PIN code, see SIM card
lock on page 36.
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 it
from your phone. You can also save contacts in the phone
memory. See Contacts on page 27.
If you enter the wrong PIN three times in a row,
PIN blocked appears. To unblock it, you need
to enter your PUK (Personal Unblocking Key).
