One of my friend is using prepaid mobile connection. He don’t want to use postpaid connection because Internet connection is very cheap in prepaid. Now the problem is he wants to monitor Internet data usage of his phone.
As he is using smart phone powered with Android OS, it is very simple task.
To monitor the data usage on Android you can use 3G Watchdog
3G Watchdog data counter monitors your Mobile Internet (4G/3G/Edge/GPRS) data usage, shows a status icon (green/orange/red) in the notify bar and a detailed report page. Widget (2 sizes). And much more!
It only does data, and nothing else. This doesn’t generate fancy graphs. However, it does predict your usage pattern. You can see daily, weekly, or monthly history. You can even export your data from previous periods to be imported later for better prediction. You can also add or subtract usage daily, weekly, or monthly.
It will also give you a notification icon if you need to know you’re in the green, yellow, or red.
It will also disable your data to make sure you don’t go over, but you will need JuiceDefender or APNDroid installed.
This application is free for use. There is also a pro version with some more functions.
You can download the free version from here
