Monitor your data usage with the native data monitor function in BlackBerry 10.3.1
The latest BlackBerry 10 OS update to 10.3.1 brought many new features and imnprovements. One new feature is the addtion of data monitoring. Before BlackBerry 10.3.1 you had to make use of apps in order to track your data usage, while those apps still exist, you now have a native option. Most will say it now renders those apps obsolete but it really depends on the features and choice is always good.
