Databack is an application which is very useful app to those people who always in online, who uses data alot.
The concept was ULTIMATE
Recently I have installed this app, I was satisfied with this application, and daily two spins will be available for the user.
These kind of apps you people found rarely, and in those this one is the BEST
But it retains the data slowly
However this is good to use
I suggest everyone to download and install this app
My databack status is provided below with screenshots
THANK YOU
