Is there a way I can tell just by looking at the phone if it is unlocked and works with any carrier?

Explanation:

I'm going to buy the phone from a guy, and he is not sure if the phone is unlocked or not. The phone is still in a box, it was a gift and came with a T-mobile SIM card that he never used. He is not paying any monthly fee for it.
