Unlocked BB and Straight Talk

I have a straight talk nokia e71. I just bought an unlocked verizon blackberry 9930. To spite that the straight talk website says I'm compatible upon typing in the meid number, a straight talk rep says I can't use a verizon bb. The site also says that I don't need a sim, just the registration # and the activation key. I can't use the sim from my e71. I tried that before reading into this at all. After reps telling me that I can't use it, I don't want to scratch the card for the code so I can return it if I can't make it work. I hope that this makes sense to someone. I need to know what an unlocked phone is exactly if it's still conn to verizon somehow, and if I can make it work with straight talk. If so, obviously, how to go about it. Any help is much apr. Thx

If the 9930 is unlocked, you can use it on Straight Talk's AT&T or TMO service, but you will not get data and you will be on 2G. Straight Talk does not offer BIS data plans--which older BBs require.

Are you sure the 9930 is unlocked? It wouldn't come unlocked by default, unless it's a used phone and the previous owner unlocked it before selling it to you.

I bought it in inbox condition advertised as unlocked. Not one person in whatever country they are in can make it work.
