I have bought approx. 30 x $30 Telstra Sim Kits.
They were really cheap.
Other than sell them online,what can I do with them?
All advice will be appreciated.
Activate them, use them…. :D
Put them in a mobile phone, call people.
Don't be silly grandpa
Why the hell would you want 30 prepaid packs?
If you don't know what to do with it, I'll take it off your hand, just send to me.
You can use them on the google play store. E.g. I used mine to stack a few years of google play music subscriptions.
