Recently I took a trip to Europe. I needed a simple way to track the data usage on my iPhone and iPad. As you probably know, 3G roaming costs add up quickly if you're not paying attention.
What to do? Easy. Just reset the usage statistics on your iOS devices when you arrive in foreign lands. Here's how to do that with your Apple iPhone and iPad.
On the iPhone, tap Settings.
On the Usage screen, notice all the stats. Tap Reset Statistics to reset Call Time and Cellular Network Data.
To confirm, tap Reset Statistics.
Notice that after the reset, the stats for Call Time and Cellular Network Data are clear.
The steps are similar on the iPad. First, tap Settings.
Now, tap General, Usage, and Reset Statistics.
Confirm by tapping Reset.
With your statistics all reset, it's easy to monitor call time and data time. If you don't have an unlimited data plan, you'd better get one.
