You can change your network security code to
the new one using the PC if you have the
"docomoID"/"Password" for the "My docomo"*
General support site for PC (in Japanese only).
* For information on "My docomo", see the
previons page of the last page of this
manual.
You can set a security code called PIN code
to the UIM. The code is set to "0000" at the
time of subscription. It can be changed by
yourself.
PIN code is a 4- to 8-digit number (code) that
must be entered for user confirmation to
prevent unauthorized use by a third party
every time you insert the UIM into the FOMA
terminal or when the FOMA terminal is
powered on. Entering the PIN code enables
making/receiving calls and terminal
operation.
･
When you purchase a new FOMA terminal
and use the UIM that you have used on the
current FOMA terminal by inserting to the
new one, use the set PIN code on the former
terminal. If you did not change the setting,
the code is "0000".
･ If you enter a wrong PIN code 3 times
consecutively, the PIN code is locked and
cannot be used anymore. In this case,
unlock with "PUK". (P.106)
PUK code
The PUK code is an 8-digit number for
canceling the locked PIN code. The PUK
code cannot be changed by yourself.
･
If you enter a wrong PUK code 10 times
consecutively, the UIM is locked. Please
contact a docomo Shop.
By setting PIN (security code) and enter PIN
code when powered on, you can protect the
UIM from improper use.
