U.S. Senators Jay Rockefeller and Amy Klobuchar want wireless carriers to change the way they do business, including offering consumers prorated early termination fees for switching carriers.

In legislation introduced Sept. 7, the two lawmakers called for a wide range of new policies calling for wireless carriers to provide “simple, clear information” on their services and charges, a 30-day window in which to exit a contract without early termination fees and greater flexibility to exit contracts with services that don’t meet a consumer’s needs.
