CLEVELAND, Ohio -- The Federal Communications Commission is looking into widespread billing problems at Verizon Wireless, the nation's largest wireless carrier.
The regulatory agency is receiving complaints about Verizon following a series of Plain Dealer stories in the last 10 days that raised questions about unexplainable explosions in cellular data use among thousands of Verizon customers nationwide. In many cases, the supposed increases in the use of data on smartphones led to over-limit fees or caused people to buy larger a data plan to avoid fees.
