What is PUK code
If you have set a SIM card lock, you will be asked to enter the PIN when you turn on your devide. Your SIM card will be locked automatically if you have entered an incorrect PIN too many times. You will then be asked to enter a PUK code to unlock the SIM card.
If you need the PUK code to unlock your SIM card, please contact your Telecommunications Services Providers.
Note: A SIM card PIN is the password for your SIM card and is only required when you turn on your device, which is different from the screen lock for your device.
