Hello, Freiend today I am here to share my opinion on the app called DataBack this app saves your internet data not so use full like you wont be saving 100MB per day, But yes it saves data and give you 500 MB Per Month,
The app also gives you two chances to win some 4g data, everyday you will get two spin or chance to click on Win 4g by clicking this option you can win 5mb 10mb or 15mb depending on your luck.
Overall its a good app to save some data or win ! By just installing this app, we can save some data or get some free data so I dont think its a bad deal.
