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 removing it from your phone. You can also save contacts in the phone memory. See Contacts on page 22.

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.

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).
