Data usage manager -DUM

DUM will manage both Cellular (4G/LTE/3G/Edge/GPRS) and Wi-Fi data usage in real time from your device.

This app will let you be in control of your data usage to avoid the costly overage charges your provider may charge.
DUM manages data usage from the device itself and is not dependent on setting up or logging into your network providers server or website.

Nothing more or less.
