I have no idea if the unlock code works on other phones, I still ain't gonna provide it anyway.
I had an old Greek SIM Card that's been in my wallet forever (I used to have a quad-band unlocked phone for foreign traveling).
I called Verizon tech support, make sure to request Global support, as they can verify and give you the unlock code. Once they gave it to me, I turned off my phone, removed the Verizon SIM Card and replaced it with the Vodaphone SIM Card behind the battery. I rebooted my phone and when my phone rebooted the "Unlock" screen appeared. I entered in the unlock code given to me, and pressed "Unlock".
"Device Unlock Successful!" appeared.
