Pantech C3b - Manual (Page 91)

The following section describes various security codes used
on your phone.
PIN1 code (4 to 8 digits)
The PIN1 (Personal Identification Number) code protects
your SIM card against unauthorized use. The PIN1 code is
usually supplied with the SIM card. If you input the incorrect
PIN1 code entry three times in a row, the PIN1 code will be
blocked. If the PIN1 code is blocked, you need the PUK 1
code to unblock before you can use the SIM card again.
See information on the PUK1 code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required
to access some functions, such as call cost counters.
Contact your carrier for information.
Lock code
The lock code can be used to lock the phone and keypad to
avoid unauthorized use.
PUK1 and PUK2 codes (8 digits)
The PUK1 (Personal Unblocking Key) code is required to
change a blocked PIN1 code. The PUK2 code is required to
change a blocked PIN2 code. If the codes are not supplied
with the SIM card, contact the operator whose SIM card is
in your phone for the codes.
Avoid using access codes similar to emergency numbers
such as 112, to prevent accidental dialing of an emergency
number.
Network Barring Password (4 digits)
The N/W password is required when you use the N/W
Barring function. Your service provider will provide the N/W
password to you when you subscribe to this function.
You can change this password using the Call barring
function.
(For further details, see Security on page 83.)
