Are you using this card?

You will have to get off that cover. And see if the chip inside is that perticular model.

Now if your not willing to do that, I'm afraid this is real hacking here so. Peel the metal cover off with a pliers (if you have pliers that is!!!). Take a photo and upload it!
Good luck.
