The next calling cycle, like before, I went over on my data. I honestly think it's a conglomerate of different things...many of which are not in our control at all (IE: erroneous data usage while the iPhone is completely powered down and SIM removed for instance)...and I don't think we're going to ever find a real solid target when it comes to WHY because it's something the carriers make money on every second of every day.
Agreed, and that is why it's important for you to keep track of your normal usage. Something that arguably intended to be ammo for the carriers has become ammo for the users is data usage history. We are creatures of habit and our usage displays it so when they try to jack you with overages and you're not overseas or anything, you use that history to your advantage and force them to prove otherwise. If you're a customer in good standing, the odds will be in your favor a majority of the time, in my opinion and experience.
