You will never believe until you give it a trial. The tweak was tested and working fine before posted, it doesn't require any Airtime, you can get it done with N0.0k balance, but it is working on some selected Airtel SIMs, not on all SIMs, so if you try it with a line and is not working, don't be panic, try to find another Airtel SIM to get it done. I have 3 different Airtel SIM, only one of them was lucky to received free 100MB and one of my closest friends received 200MB on each of his 2 Airtel SIM. Just follow the below steps to get it done on your Airtel SIM.
First of all, your Airtel SIM must be on club 10 PAddi.
Dial *166# to migrate to club 10 PAddi.
After you have successfully migrated to club 10 PAddi,
Just dial *141*13*200# to receive free, 200MB or
Dial *141*13*100# to receive free 100MB
It is simple as that, enjoy it while it last.
Hope this information helps?
