GPP unlock Sim did not work

I bought a GPP sim unlocker. I did what I needed to do. I entered the code when it says "bind key" or something like that. When I clicked "ok" it kept telling me to put in the code. I thought I probably got the numbers mixed up, so I put it in again and made sure that it was correct. But I clicked "ok" and it still told me to put the code in. Then I notice in the message box. It's saying "The" just "The" and nothing else. I told the people about it, so they sent me another one. And it did the same thing! I don't know if its my iPhone or what. It's a Verizon iPhone 4S 16 GB that was disconnected from Verizon. At the time it was running iOS 6, now it's running 6.1.3. The Windows OS was an old type, I don't know which kind it was but it wasn't Windows 7, XP, Vista, or 8.Is it my iPhone, the GPP, or the computer operating system?

Right now GPP doesn't work for 6.1.3. There's even no jailbreak out for 6.1.3. As far as I know, GPP and Rsim7 are only for 6.0 - 6.1.2 as of right now…
