Notes on the security codes
･
To set a security code, avoid imaginable numbers such
as "birth date", "a part of phone number", "street
address or room number", "1111" or "1234". Maintain a
separate record not to forget the numbers.
･
Be careful never to reveal your security code to others.
If a security code is misused by others, DOCOMO
assumes no responsibility for damages resulted from it.
･
If you forget your security codes, you need to bring a
document (a driver's license etc.) to identify your
subscription, the terminal and the docomo nano UIM
card to a docomo Shop. For details, contact "General
Inquiries" on the last page of this manual.
･
The PUK code is written on a subscription form (copy
for user) handed at subscription in a docomo Shop. For
users subscribed in other than docomo Shop, bring a
document (a driver's license etc.) to identify your
subscription and the docomo nano UIM card to a
docomo Shop, or contact "General Inquiries" on the last
page of this manual.
❖
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 a docomo
Shop, 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.
･
For details of network security code, refer to NTT DOCOMO
website.

❖
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 is a 4- to 8-digit number (code) that must be entered each
time you insert the docomo nano UIM card into the terminal or
when the terminal is powered ON for user confirmation to
prevent unauthorized use of the docomo nano UIM card by a
third party. 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.
