I bought a brand new boost mobile phone off of ebay, brand new in the box, never opened, with unused simcard and everything, but when I try to activate it, it says invalid activation pin. I got it at a really good price, from a company that sells alot of refurbished products so I'm not sure where they got it.

My question is, would there be anyway to get a valid activation pin to use with a simcard that's never been used before?
