The whole text messaging phenomenon is really misunderstood by many adults. Clark recently heard a government regulator in the telephone industry admit he's not familiar with texting. Parents are often similarly oblivious. That's why unlimited text messaging is a real help. If you have text-happy teens, it helps ensure that your kids don't run your bill into the ground every month. But those unlimited plans don't cover all text messaging services -- especially some premium services that are advertised on MTV and elsewhere. There was a recent news report about one developmentally disabled teen that ran up a $10,000 bill in one month using these services. The sad thing is that the child's parents had an unlimited text messaging plan through Sprint. The cell phone carriers get a kickback for doing the billing, so there's no real incentive for them to modify their practices. Parents need to be aware of this danger and teach their children not to give into alluring services that offer dating opportunities, a joke of the day or horoscopes sent directly to their handsets, among other things. But there's a larger problem here. How can you even get the FCC on this issue if the commissioners don't know what text messaging is?!
