PIN code
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.
