The cell phone and SIM card use several accessing
passwords. These passwords help to prevent the cell
phone from being embezzled.
You can use the function options in the security settings of
settings menu to change accessing password (except for
PUK and PUK2).
PIN Code
PIN code (Personal Identification Number) can prevent the
SIM card from being embezzled. The PIN code is provided
along with the SIM card. If the PIN code checking is
activated, it is necessary to input the PIN code when the
cell phone powers on every time.
If a wrong PIN code has been input for 3 times straight, it
is needed to input the PUK code, then input a new PIN
code and input it again for confirmation.
Accessing Password
PIN2 Code
Some SIM cards may provide PIN2 code, while PIN2
code needs to be used in some functions like Call Cost.
These functions can be used only if the SIM card
supports them.
