[Zap]

last month i went to 500gb out of 250gb and i didnt get charged does this mean im free to take advantage of this?
also ive done this before month to 600gb and havent been billed

Nope,if they charge for going over you will get billed.Don't forget you pay you bill in advance so anything new will be a month late.If it goes another month then my guess is you won't see a charge.

i wouldn't do that if i was you cause you could end up with a biggggg bill soon
