Chapter 5 Reference Information
Access Password
The handheld and SIM card support multiple
passwords to protect against unauthorized
access.
PIN
The Personal Identification Number (PIN)
protects the SIM card against unauthorized
access. Usually the PIN is provided with the
SIM card. When the power-on PIN is enabled,
you need to enter this PIN each time you power
on the handheld.
Note:
If you enter an incorrect PIN three times
consecutively, the SIM card is locked. Then you
need to enter the PUK to unlock the SIM card.
Certain operators do not provide the PUK.
Therefore, if you are asked to enter the PUK,
contact your operator immediately. Do not enter
any characters on your own.
PIN2
Usually PIN2 is provided with the SIM card.
PIN2 implements certain functions, such as the
charge rate. These functions are implemented
only when supported by your SIM card.
If you enter an incorrect PIN2 three times
consecutively, PIN2 is locked and you need to
input PUK2 to unlock PIN2.
PUK
PUK is used for changing a locked PIN. PUK is
provided with the SIM card. If it is uncertain,
contact your local service provider. If you enter
an incorrect PUK ten consecutive times, the
SIM card cannot be used any more. Contact
your local service provider for a new SIM card.
The PUK cannot be changed. If the PUK is lost,
contact your service provider.
PUK2
PUK2 is usually provided with certain SIM
cards. PUK2 is used to change a locked PIN2.
