    Ask ATnT to give u a replacement sim for the old one. they will give you. might charge you, but its better to get a replacement from them.tell them you have a smartphone which is asking for a newer generation Sim Card.
    i'll suggest you not to fiddle with the chip on the sim. if you manage to scratch it even a little bit it'll not work after that.

    The newer phones only work with sim cards that have the first four numbers 8901.

    Hope that helps
