Unfortunately, when it comes to data download allowances many network operators had adopted Orwellian doublespeak and decided to redefine the meaning of unlimited as limited.
If you’re on one of these contracts, or even a Pay As You Go deal with a tighter data allowance, then 3G Watchdog can help you keep track of your data usage to make sure you don’t get stung by penalty fees. It sits in your Android notification tray and tracks the amount of data you use on your GPRS or 3G connection.
Once you enter your data allowance and the length of time the allowance is valid it’ll even show you a percentage figure of how close you are to your limit. There’s also a widget that you can place on your desktop that provides a large graphical view of your current usage figures.
3G Watchdog is a simple but effective way to keep track of your data allowance.
