PIN code
You can set a PIN code for the docomo mini UIM card. PIN code
is set to "0000" at the time of contract, but you can change the
number later (
Z
P.159).
The PIN code is a four-to-eight digit number (code) for checking
the user each time the docomo mini UIM card is installed or
each time the terminal is turned on, to prevent unauthorized
use by a third party.
You can operate the terminal by entering the PIN code.
• If you use a docomo mini UIM card that you used for another
terminal or mobile phone in this terminal, enter the PIN code
you set for the old terminal. The code is "0000" if you have
not changed it.
• If you fail to enter PIN code correctly three times in
succession, PIN code is locked and disabled. In this case,
unlock the PIN lock with "PIN unblocking key".

PIN unblocking key (PUK)
The PIN unblocking key (PUK) is the eight-digit number for
releasing the blocked PIN code. You cannot change this
PIN unblocking key by yourself.
• If you fail to enter PIN unblocking key (PUK) correctly ten
times in succession, the docomo mini UIM card is locked. In
this case, contact a docomo Shop.
