Security codes for the terminal
Some functions provided for convenient use
of the terminal require the security code to
use them. Besides the security code for
locking the terminal, the network security
code necessary for the network services etc.
are available. Make use of the terminal using
an appropriate security code according to
the purpose.
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
drivers license), the terminal, and docomo
mini UIM card with you to the nearest
docomo Shop. For details, contact the
"General Inquiries" on the last page.
