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.
You can save contacts on the SIM card before you remove it from your phone. See Contacts on page 27.
PIN code (SIM card lock)
You may need a PIN (Personal Identification Number) to activate the services and functions in your phone. Your PIN is supplied by your network operator. Each PIN digit appears as *, unless it starts with emergency number digits, for example, 112 or 911. You can see and call an emergency number without entering a PIN. To use the SIM card lock or change your PIN code, see SIM card lock on page 35.
If you enter the wrong PIN three times in a row, the SIM card is blocked. See SIM card lock on page 35.
