Ladies and gentlemen, boys and girls, the time has come for you to stop worrying about receiving an astronomical monthly bill from your network provider telling you that you owe them an extortionate amount of money due to the fact that you have massively exceeded your cellular data download limits. In my experience, cellular data is a varying beast. One month I can hardly use it, and the other, I can go way over my allocated service plan limit, meaning that it is very difficult to gauge an average of how much I am likely to use.
