Notes on the security codes
･
Avoid using a number that is easy to guess, such as "birth
date", "part of your phone number", "street address number or
room number", "1111", and "1234". Make sure to make a note
of the security code you set lest you should forget it.
･
Be very careful not to let others know your security code. If your
security code is known by anyone else, DOCOMO shall have no
liability for any loss due to any unauthorized use of it.
･
If you forget your security codes, you must bring your official
identification (such as driver's license), the terminal, and
docomo nano UIM card with you to the nearest docomo Shop.
For details, contact the "General Inquiries" on the last page.
･
The PUK code is written on the subscription form (copy for
customer) handed at the subscription in the docomo Shop. If
you subscribed other than docomo Shop, you must bring your
official identification (such as driver's license), the docomo
nano UIM card with you to the nearest docomo Shop or
contact the "General Inquiries" on the last page.

Network security code
The network security code is a 4-digit number necessary for
identification or using the docomo network services at reception of
your request in docomo Shop, or at docomo Information Center or
"
お客様サポート
(Customer support)". It can be set any number at the
subscription and also changed later by yourself.

■
PIN code
You can set up a security code called a PIN code for your docomo
nano UIM card. At the time of subscription, the code is set to "0000",
which you can change by yourself.
PIN code is a 4- to 8-digit security number (code) that must be
entered for user authentication to prevent unauthorized use of
docomo nano UIM card by a third party every time you install the
docomo nano UIM card into the terminal or when the terminal is
powered on. Entering the PIN code enables making/receiving calls
and terminal operation.
･
For using the docomo nano UIM card that you have used on
another terminal by inserting to this terminal, 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 (PUK lock) and cannot be used anymore. In this case,
unlock with "PUK". Unlock the PIN code before setting new PIN
code.
■
PUK code
The PUK code is an 8-digit number for canceling the locked PIN code.
The PUK code cannot be changed by yourself.
･
If you failed to enter PUK code 10 times consecutively, the docomo
nano UIM card is locked. Please contact a docomo Shop.
