All of the posts regarding discounts for AT&T are incorrect (I am a supervisor for AT&T Mobility). AT&T discounts the rate plan on an individual plan or the primary line on a family talk/business talk group plan. They also discount any data plan higher than the base one (formerly 250MB, now 300MB). That's it. Features are not discounted. That includes messaging, subscriptions, international long distance or roaming, overage, etc.
Thanks for clarifying. Can you tell me if you discount unlimited messaging on a family plan? Also, are all the data plans on a family plan discounted if they are higher than the base one?
Thanks
