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)
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.
You can save contacts on the SIM card before you
remove it from your phone. See Contacts on page 27.
If you enter the wrong PIN three times in a row, the SIM
