Precautions about various security codes
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.
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.
If you forget your security codes, you are required to bring your
identification (a driver's license etc.), your handset and your
docomo mini 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 mini UIM card to a docomo Shop or contact the
number listed in "General Inquiries" on the last page.
Security key (security code for various functions)
■
If you set any restrictions, you need to enter the security key to
temporarily disable them. [Passcode] ([0000]) is set as a security
key by default but you can change it (nP. 68 "Changing security
key").
If you enter wrong security keys five times continuously, you
cannot enter it for 30 seconds.
■ 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" (Support),
used for accessing various network services, etc. You can set any
code at the time of subscription but you can change the code.
For details on network security code, refer to the DOCOMO
website.
PIN code
■
A docomo mini UIM card has a security code called PIN code. This
security code is set to [0000] by default but you can change the
code (nP. 68 "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 mini UIM card is inserted or when a device is turned on to
prevent unauthorized use of the docomo mini UIM card by a third
party. Making/Receiving a call and the device operation are
enabled by entering PIN code.
Use the previously set PIN code when inserting a docomo mini
UIM card that has been used in another device. It is [0000] if the
setting has not been changed.
If you enter wrong PIN codes three times continuously, it is
locked and the docomo mini UIM card becomes unavailable. In
this case, unlock with "PUK" (PIN Unlock Key).
PUK (PIN Unlock Key)
■
PUK (PIN Unlock Key) is an eight-digit number used to disable the
PIN code lock. You cannot change the code.
If you enter wrong codes ten times continuously, the docomo
mini UIM card is completely locked. In this case, contact a
docomo Shop.
