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 you remove it from your phone. See To copy names and numbers to the SIM card on page 19. PIN 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 see and call an emergency number without entering a PIN. If you enter the wrong PIN three times in a row, the SIM card is blocked. See SIM card lock on page 62. Flight mode In Flight mode the network and radio transceivers are turned off to prevent disturbance to sensitive equipment. You can use the Bluetooth™ function in Flight mode. Startup screen The startup screen appears when you turn your phone on. See Using pictures on page 39. Standby After you have turned your phone on and entered your PIN, the name of the network operator appears. This view is called standby. 6 Getting started This is the Internet version of the User's guide. © Print only for private use.
