You can put a limit to the amount of data used. Under setting, go to data usage, and check set mobile data limit. That way you can monitor that data being used.
Besides the above also disable automatic updates in Google Playstore.
Also you may go to settings and select Data Usage and see which app consumes more data. You can move the 2 sliders to a particular day or days you want and see which app has consumed a lot of data. You may either uninstall that app or change its setting to avoid any automatic Internet communications. Disable Google location if you wish to. Also you may turn OFF automatic synchronisation if you wish to.
