MocoNews is reporting that Chicago-based U.S. Cellular, which has a customer base of six million customers in 26 states and is the country's sixth largest carrier, is now offering a $99-per month flat-rate call plan, following the mob rush from the major carriers earlier in the week.

U.S. Cellular's plan is supposedly only for a "limited time," though we doubt that in the face of competitive pressure. The MocoNews report also said that Cellular South, a network that serves Memphis, Mississippi, and coastal areas of Alabama and the Florida Panhandle, has been offering a $79 plan since last October, but apparently no one noticed.
