Do not reveal your security codes to others.
DOCOMO is not responsible for damage
caused by misuse of your security codes by
others.
If you forget your security codes, you need
to bring your identification document,
driver's license, etc., the FOMA terminal and
the UIM to a docomo Shop. For details,
contact "General Inquiries" provided on the
last page of this manual.
Your PIN unblocking key is written in the
application form (copy for subscriber) given
at the time of contract. If you have
subscribed at a place other than a docomo
Shop, bring your identification document
(driver's license, etc.) and the UIM to a
docomo Shop, or contact "General Inquiries"
provided on the last page of this manual.
● Network security code
The network security code is a 4-digit number
necessary for using the docomo Network
Services or identification at reception of your
request in docomo Shop or at docomo
Information Center. It can be set any number
at the subscription and also changed later by
yourself. You can change your network
security code to the new one using the PC if
you have a "docomo ID/Password" for General
support site for PC "My docomo".
NOTE
For information about "My docomo", see the
inside of the back cover of this manual.
● PIN1 code/PIN2 code
The UIM has two types of security code,
namely PIN1 code and PIN2 code. These
codes are set to "0000" at the time of
subscription, but you may subsequently
change it. PIN1 code is a 4- to 8-digit number
that is entered to identify the user when the
UIM is inserted in the FOMA terminal or the
terminal power is turned on. It is intended to
prevent unauthorized use of the FOMA
terminal by a third party.
Entering PIN1 code makes the FOMA
terminal operable.
NOTE
This FOMA terminal does not support PIN2
code.
If you want to use a UIM that has been
used on a different FOMA terminal, use the
same PIN1/PIN2 code that had been set on
the different terminal. The code is "0000" if
the default setting has not been changed.
If you enter the incorrect PIN1/PIN2 code 3
times in succession, the PIN1/PIN2 code is
locked. Unlock using "PUK code".
● PIN unblocking key (PUK)
The PIN unblocking key (PUK) is an 8-digit
number used to unblock the PIN1/PIN2 code.
You cannot change it by yourself. If you enter
the incorrect PUK code 10 times in
succession, the UIM is locked. If this
happens, please contact a docomo Shop.
