PIN1 Code and PIN2 Code
You can set two Security codes, namely
PIN1 and PIN2, for the UIM (FOMA card).
These codes are set to “0000” at the time of
subscription. They can be changed by yourself
(P.133).
PIN1 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. Only
after you enter the PIN1 code, you can use the
FOMA terminal for placing/receiving a call and
other operation.
PIN2 is a 4- to 8-digit number (code) that must
be entered in order to reset the total call cost,
use a user certificate, or request the issue of a
user certificate.

If you continue to use the current UIM with a newly
purchased FOMA terminal, use the previous PIN1
and PIN2 codes you set for the UIM.

PUK Code
The PUK code is a 8-digit number for
canceling the locked PIN1/PIN2 code. The
PUK code cannot be changed by yourself.

If you enter a wrong PUK code 10 times
consecutively, the UIM is locked.
