Im using databack for a year and have saved a lot of data and recharged to many numbers with jio.This app is the best way to save data and with the help of jio.The app is best choice for saving data for further recharge for me.I have still saved 196 mb data and will be saving in the future too.
Databack is still not a scam .it recharges and till now I saved up to 2.35gb and recharged too.
THANK YOU.
