MexiCali59 writes "The FCC is expected to launch a proceeding at its Thursday meeting that could force wireless providers to change their billing practices. The agency wants to prevent consumers from unknowingly racking up oversized bills on their phones when they go over their minutes, a situation the agency calls 'bill shock.' The agency released a survey earlier this year that showed one in six American consumers had been surprised by a cell phone bill. The FCC's proposed rules would require carriers to send text or voice alerts before and when minutes are used up. Notifications would also have to accompany out-of-country charges, and carriers would be required to clearly disclose any tools they offer to simplify billing."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
