Suggestion.... No more like request. How about you allow parent to restrict time of day that a child makes or receives a phone call.
OH no, dont give ATT any more ideas on how to restrict, it might get rolled out to all of us where we end up buying package plans that determine what time of day we can use our phones... (snarcastic, but scary thought)
I would rather see an app developed and pay a one time price , install, and set up time schedules that may make the phone disabled at a predefined timespan. If ATT does it, you'll be charged monthly . oh noooo, lets not encourage them... (good aTT doesnt read the forum, right?)
