I too got a message within less than 24 hours that I exceeded my plan & charged another $25 after initial $40..hadn't even made it to my destination..& don't even know what I exceeded or what's left. Lousy plan in airplane mode. Why isn't there a way to tell what I'm using so I don't go over? Never again will I waste money on this..I have to remember to turn off data every time I leave Wifi. This is nuts.
