manual.

PIN code

You can set a security code called PIN code
to the UIM. The code is set to "0000" at the
time of subscription. It can be changed by
yourself.
PIN code is a 4- to 8-digit number (code) that
must be entered for user confirmation to
prevent unauthorized use by a third party
every time you insert the UIM into the terminal
or when the terminal is powered on. Entering
the PIN code enables making/receiving calls
and terminal operation.
･ When you purchase a new terminal and use
the UIM that you have used on the current
terminal by inserting to the new one, use the
set PIN code on the former terminal. If you
did not change the setting, the code is
"0000".
･ If you enter a wrong PIN code 3 times
consecutively, the PIN code is locked and
cannot be used anymore. In this case,
unlock with "PUK". (P.108)

PUK code

The PUK code is an 8-digit number for
canceling the locked PIN1/PIN2 code. The
PUK code cannot be changed by yourself.
･ If you enter a wrong PUK code 10 times
consecutively, the UIM is locked. Please
contact a docomo Shop.
