Default [Q] Network unlock request unsuccessful- Moto Flipside

I bought a new motorola flipside from ebay and I tried to unlock it by code. But the message that is displayed it " network unlock request Unsuccessful" . I have tried several websites and vendors on ebay for unlock codes. But all of them said that the code is not found. One of them also said that the mobile phone must have been reported stolen.

Can someone please help me out here. Is there a software to unlock it?
