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.
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 19.
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.
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 42.
