Pin Code; Network Security Code - NTT docomo Optimus LTE L-01D Instruction 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 to
any number at the subscription and also changed later
by yourself. You can change your network security code
to the new one through PC if you have a "docomo ID/
Password" on General support site for PC "My docomo".
Note
• For information about "My docomo", refer to
P246.

PIN code

The UIM can set security code named PIN code. This
code is set to "0000" at the time of subscription, but you
can subsequently change it.
PIN code is a 4- to 8-digit number that is entered to
check the user when the UIM is inserted in the terminal
or the terminal power is turned on. It is intended to
prevent unauthorized use of the terminal by a third party.
You can use the terminal by entering PIN code.
Note
• If you use a UIM that has been currently used
when you buy a new terminal, use the same PIN
code that had been set on the current terminal.
The code is "0000" if the default setting has not
been changed.
• If you enter incorrect PIN code three times in
a row, the code will be locked. In that case,
unlock with "PUK code".
