A PUK code is a security feature on your sim card that, where you can choose to have your sim request a PIN code when your phone is switched on. If this code is entered incorrectly three times, your sim card will lock itself, and this can only be unlocked using your PUK code. As your sim card is controlled by your network, it is your network that can provide you this code- you will need to contact them and request this.
Well it doesn't block your card, it just blocks your sim card, If you will try a diffrent SIM in your phone that will work and if you want your sim to unlock than contact your Connection service provider means the company from you have you phone connection and you need to give them your sim no, which wouldb located at the back of your SIM and they will provide you with your PUK no for the SIM card.
A PUK (Personal Unblocking Key) is the code required for enabling/unlocking a sim card. This disabling/lock is a result of erroneously entering the PIN (Personal Identification Number) multiple times. Depending on the SIM card issuer, erroneously entering the PUK code multiple times would result to a permanently blocked/disabled SIM card. The PUK code is an OTW (one time write) only and therefore the only way to open the card is with the PUK code.
In all instances, it has nothing to do with the phone itself but with the SIM card, hence, the LG Vu CU920 would still work with another SIM card.
Hope that this be of initial help/idea. Good luck and thank you for using FixYa.
Pin Unlock Code (PUK) If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
