What are the data overage costs?
The data overage costs are 3 cents per kilobyte (as of the time of this writing) for a non-BlackBerry plan. While high, you can use a BlackBerry cautiously enough by doing things such as turning off images during web browsing. While the BlackBerry does not have a data counter, many applications such as Opera Mini and Google Maps Mobile, have a built-in data counter which you can read the total download, and make sure you don’t use too much.
