The PUK is a unique number that is assigned to your SIM card. Your SIM is blocked not the phone. If you try another SIM in the phone it should work just fine. In order for you to unlock your SIM, you need to check the papers that you got with your SIM card, the PUK1 and PUK2 should be on that paper. When your phone is security code lock usually you need the PUK2 to unlock it but some phones use the PUK1 to unlock it, you'll need to get this information from your service provider. If you don't have the papers for the SIM you'll need to contact your service provider for the PUK, some companies may require you to verify that you are the owner before they provide it to you.

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.
