Wow! That's a lot of sim cards ggking7. As for checking balance, most sim cards already have the number stored on them. For those that do not, I store it on there myself. Just like PhotoJim, I use a plastic that's meant to hold drivers licence, bus pass, etc. I only use this for a couple of sims. I have enough unlocked phones for the remaining sims. So, they are just in the phone.
