On September 27, 2012, the FCC conducted a single round, sealed bid, reverse auction to award up to $300 million in one-time Mobility Fund Phase I support to successful bidders that commit to provide 3G, or better, wireless service in areas designated as unserved by the FCC.

U.S. Cellular and several of its wholly-owned subsidiaries participated in Auction 901 and were winning bidders in eligible areas within 10 states and will receive up to $40.1 million in one-time support from the Mobility Fund.
