When you buy a SIM card, you will get a piece of plastic with detailed information about the carrier, which includes the PIN and PUK codes. The PIN is short for Personal Identification Number, which is needed for accessing the operator's mobile network. The first time you insert your SIM card into your iPhone, you'll need to enter the PIN code.
You can continue to use or disable the code or change it as you want. If you continue using it, you'll need to enter that code whenever you restart your device or remove your SIM card. That makes it easy to forget the PIN code because we rarely need to restart our device or change the SIM card.
You will be locked to your SIM card if you enter the wrong PIN code three times. To unlock your SIM card, the PUK comes to help. But most people tend to discard the plastic after entering the SIM card. So the problem comes: how to unlock the SIM card without a PUK code?
