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
terminal or when the terminal is powered on.
Entering the PIN code enables making/
receiving calls and terminal operation.
･
If you use a newly purchased terminal with
UIM you have been using inserted, use the
PIN code set 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.126)
PUK code (Personal Unblocking Key)
The PUK code is an 8-digit number for
canceling the locked PIN code. The PUK code
cannot be changed by yourself.
･
If you failed to enter PUK code 10 times
consecutively, the UIM is locked. Please
contact a docomo Shop.
By setting PIN (security code) and entering
PIN code when powered on, you can protect
the UIM from improper use.
