I love my Altoid tin, also. It can store the original cards that the sim cards came on (which sometimes have needed info) and any type of recharge cards you might have. And of course you have an excuse to have "just one more" Altoid if you need the tin. Also best to wash (lick?) out the "Altoid dust" before using.
I also find that sim cards fit well in the little plastic cases that the SD cards come in. I can get a few of them in a tin allowing for some organization. Haven't tried the fancy $5 cases.
Probably less likely to get stolen by the smurfs, too and contributes to cleaning up the environment by recycling. It just doesn't get any better than that.
