unlimited sim cards what to do?

I have this little store in my village where you can get free sim cards, if already used them to verify twitter accounts for twitter bots and for email and some other stuff.
but I am not making money of the twitter accounts if also stopped working on then several months ago.
so does anyone know a way I can make some money with the sim cards of course I can only take like 4-5 there a week or so because its at the register.
(can also ask friends to get some for me)
and I also found out that after 84 days of no use it expires that really suck for me because I have like 30 of them.

would like to hear if you have some ideas.

selling PVA Accounts
selling the Cards

okay will create a sales thread here on BHW for verifying accounts with dutch phone.
then they can just fill in one of the phone numbers I have given them on skype and I will send the verfication code back
how mutch should I ask for this?

(Edit)
Didn't know opening a thread costs money anyone knows another way to sell?
