In a letter to Sprint, AT&T Mobility, and T-Mobile, Sen. Amy Klobuchar (D-Minn.) has asked the companies whether or not they’re going to start pro-rating their Early Termination Fee policies as promised, reports RCR Wireless. “Sens. Klobuchar and Jay Rockefeller (D-W.Va.) are co-sponsors of a sweeping wireless consumer protection bill” that carriers are against. In her letter, Klobuchar writes, “It is time for the wireless companies to adhere to the assurances they made to the American consumer and start pro-rating these fees.” In response, Sprint said by the end of Q2 2008, T-Mobile said the first half of 2008, and AT&T Mobility said nothing at all. (Verizon already pro-rates their ETF.)
