Puk Code - Sony Ericsson FOMA SO905iCS Manual

i-mode Password
The 4-digit "i-mode password" is required when saving/deleting My Menu or
subscribing/canceling message service or i-mode charged service, etc.
(There may be other passwords for the i-mode used by IP (information service
providers).)
The i-mode password is set to "0000" at the time of subscription. It can be changed
by yourself.
You can change the i-mode password using i-mode, by selecting [i Menu] → [English
iMenu] → [Options] → [Change i-mode Password].
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.
