Unhappy [Q] Sim unlock for Ville_C2: dream or a posibility?

Got a stock JB S-off unlocked rooted bloody unlocked everything on it today (spent the day trying to get aquainted with the One S) just to find out that the S3 is basically dead meat and no one bothers to sim unlock it. So the question is do i keep it and wait or sell it ?

In Romania we have 3 major mobile phone companies: Orange Vodafone Cosmote. I have the last one and the phone only works for the first 2. Why is not locked on 2 out of 3 ?

I can provide aditional info if needed just ask.
