When you turn on your device or while you are using the device, it prompts you
to enter one of the following codes:
Password: When the device lock feature is enabled, you must enter the password you set for
the device.
PIN: When using the device for the first time or when the PIN requirement is enabled, you
must enter the PIN supplied with the SIM or USIM card. You can disable this feature by using
the Lock SIM card menu.

several times. You must enter the PUK supplied by your service provider.

the SIM or USIM card. For more information, contact your service provider.
