Lost the card that my Sim card came in. any important info on that?

[sloan1209]

When I got my SIM card, it came in a card that I punched it out of. I lost that card but I remember there being some codes on it. were any of those important and shouldnt be seen by others?

The codes on it are the codes to identify the card. Once it's disabled and reported as lost it's useless.

However the SIM card can store contacts on it, which may be possible to get from it.
