Identify data hogs.
If you constantly go over your data limits, an app like Android Assistant may not be enough. Sure, you will be alerted when you are nearing your limit, but what exactly is causing the problem? Is it Facebook, podcasting software, the MLB Gameday app? Who knows? Well, with Onavo you can find out. The main menu displays statistics on your data use over the prior month, and it fingers the apps hogging the most bandwidth. Many of these are obvious, such as any video or streaming app, but I was surprised to see how much data Google Calendar used with its constant synching, and after consulting with Onavo, I decided to synch less frequently.
