The PUK code (the PIN unlocking password, 8 digits) is used to unlock the locked PIN code. The PUK code is
provided by the manufacturer together with the SIM card. If you have entered the PUK code incorrectly for
ten times, the SIM card will be invalidated. You need to ask your network operator for a new card.
PIN2 code
The PIN2 code (4~8 digits) is provided together with the SIM card, which is used to set the fixed dial and other
functions. Please contact your network operator to check if your SIM card supports such functions. If you have
entered the PIN2 code incorrectly for three times, the PIN2 code will be locked. The PIN2 code will be unlocked
only by entering the correct PUK2 code. The operations are as follows:
1 Enter the correct PUK2 code in line with the prompt on the screen to unlock the PIN2 code.
2 Then enter a new PIN2 code and press the OK soft key.
3 When you are prompted to reenter the new PIN2 code, reenter the new PIN2 code and press the OK soft key.
