Precautions about various security codes
z
Do not use easily predictable numbers for security codes to be
set such as “birthday”, “part of a phone number”, “address or room
number”, “1111” or “1234”. Keep a separate memo of security
codes.
z
Keep security codes private. If the security codes are found and
improperly used by others, DOCOMO shall not be liable for any
damages incurred on the users.
z
If you forget your security codes, you are required to bring your
identification (a driver's license etc.), your handset and your
docomo nano UIM card to a docomo Shop.
For details, contact the number listed in “General Inquiries” on
the last page.

PUK (PIN Unlock Key) is described in the agreement form
(customer copy) you received at the time of subscription at a
docomo Shop. If you made a subscription at a shop other than a
docomo Shop, bring your identification (a driver's license etc.)
and your docomo nano UIM card to a docomo Shop or contact
the number listed in “General Inquiries” on the last page.
Network security code
Network security code is a four-digit code required for confirming
the subscriber's identity when an order is received at a docomo
Shop, docomo Information Center or “
お客様サポート

used for accessing various network services, etc. You can set any
code at the time of subscription but you can change the code.

PIN code
A docomo nano UIM card has a security code called PIN code.
This security code is set to [0000] by default but you can change
the code (
P. 163 “Setting up SIM card lock”). The PIN code is a
four- to eight-digit security code that needs to be entered for
recognizing the user of the handset every time a docomo nano UIM
card is inserted or when a device is turned on to prevent
unauthorized use of the docomo nano UIM card by a third party.
Making/Receiving a call and the device operation are enabled by
entering PIN code.
z
Use the previously set PIN code when inserting a docomo nano
UIM card that has been used in another device. It is [0000] if the
setting has not been changed.
z
If you enter wrong PIN codes three times continuously, it is
locked and the docomo nano UIM card becomes unavailable. In
this case, unlock with “PUK” (PIN Unlock Key).
