If you enter the wrong SIM card PIN repeatedly, your SIM card will lock as an added security measure. This prevents someone from simply guessing every possible PIN to access your data if they steal your phone or SIM card.

Once the SIM card is locked, you will need to use a separate code called a PUK code to unlock it. Your carrier can provide you with the PUK code for your SIM card. You can sometimes find this on your carrier’s website after you log in, and you can usually also obtain it by calling customer service or taking the phone to a carrier store. Once you have the PUK code, you can enter it and reset your SIM PIN to the one you know.
