IMPORTANT INFORMATION
Use of Passwords
Your mobile phone and SIM card have various passwords. Those
passwords avoid unauthorized use of your phone and SIM card. You can
change PIN, PIN2 and phone password in the “Settings > Security
Settings”.
Phone Code
The Phone code can be used to avoid unauthorized use of your phone.
The factory setting for the phone code is 0000. If phone lock is enabled,
you will be asked to input the phone password when you switch on your
phone.
PIN (4 to 8 digits)
The PIN (Personal Identification Number) code protects your SIM card
from unauthorized use. The PIN code is usually supplied with the SIM
card. When the PIN code request is enabled, the password is asked
every time the phone is turned on.
Three times wrong PIN input, the SIM card will be locked and you will
need to use the PUK to unlock it. PUK is usually set by the network
operator.
1. Enter the correct PUK to unlock the SIM card, and then enter the new
PIN and press OK .
2. If you are prompted to enter the new PIN again, enter it and press
OK .
3. If the PUK is correct, the SIM card will be unlocked and the PIN will
be reset.
PUK (8 digits)
The PUK (Personal Unblocking Key) code is required to change a
blocked PIN code. Please contact your network operator for the code.
Note: Ten times wrong input in succession, the SIM card will be invalid
and you need to consult with your network operator for a new SIM card.
