On the AT&T Network, to unlock the LG Shine or CU720, it’s pretty simple:
To obtain the IMEI number, type *#06# on your device. This is a 17 digit number and it is not the same as the unlock code, this is the IMEI number to give to AT&T Technical Support in exchange for the 16 digit Subsidy Unlock Code.
to get the (16 digits code) call att and tell them you are traveling overseas, it may take two calls.
,but they should give it to you the (16 digits code)
Insert non ATT SIM
Showing 'Invalid Smart Chip'
This will take you to a screen saying you are about to unlock your phone. Do you want to proceed.
Select yes (left button)
Enter your 16digits code.
Enter your code again
Now the phone is unlocked
It requires 2 inputs of the unlock code.
If this helps solve your problem please give a fixya rating, all of them are really appreciated, sorry I cant personally tell you the code number, but ATT or your Service provider should, if all else fails, here's an online service.

SOURCE: need puk code for lg cu720
Every PUK code is unique so nobody can tell you your PUK number, but i will tell you what you can do!
1) If you still have your packet that your Sim Card came in, you should find your PUK number in there, if you don't have the packet, please read bellow.
2) You must get a phone that is on the same network as your phone and call the networks Customer Care and ask them for your PUK number, they will ask you for your phone number, then they will tell you your PUK number. Once you have done this, you will be able to reset your Pin number so you will be able to go into your phone again.
