@melmac1, from the my plan box on the upper left of the overview tab, you should be able to click on the plan feature link to see all the features the plan includes. Going back to the overview tab, the add-on box is where data from the plan is shown. The included data in a plan is treated like an add-on owing to it having limited use (not unlimited like text or calling in some plans) and for which would disappear when used up within a plan cycle. There you will see a counter which show data usage within the current plan cycle. Hope this explanation is helpful.
