Bill shock? It's "a real consumer problem that needs to be fixed," according to FCC chairman Julius Genachowski. The department teamed up with the CTIA and the Consumers Union today to address the problem of unexpected mobile bill charges. The solution? Alerts about overages and international roaming sent to subscribers before they rack up bills they can't afford. It's a plan the organization talked up last year, thanks to the findings of a Consumer Task Force. The FCC hopes that a rollout of the plan will be completed in the next 12 months.
