Well this has to be something that's happened to everyone at least once. You get a phone loaded with features, a data package, minutes, texting, the whole nine. Time goes by, everything looks ok, and then BAM, you're smacked with a hefty bill you had no idea was coming, or did you? In a report by the FCC, over 30 Million Americans are hit by "Bill Shock" which is great for wireless companies, but horrible for the users that exceed their monthly plans. No doubt this will be an issue they may fight against.
Now the FCC is planning on making it mandatory for carriers to notify their customers when overage's are about to occur. Of course most users have their own methods of monitoring their own usage, but the added backing of the FCC's new rule to Notify would definitely assist those people who no data plan can contain.
According to PCMag:
"Part of the problem, [FCC Chairman Julius Genachowski] said, is that people don't know how best to keep track of their mobile usage. "Most people still don't know what a megabyte is," Genachowski told the Times. "So it's hard to expect them to know when they have reached their limits."
