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. 

PIN code

You may need a PIN (Personal Identification Number) to 
activate the services 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 call an emergency number without 
entering a PIN.

You can save contacts on the SIM card before 
removing it from your phone. Contacts may also 
be saved in the phone memory. See Contacts 
on page 17.

If you enter the wrong PIN three times in a row, 

 

appears. To unblock it, you need to enter your PUK 
(Personal Unblocking Key).
