Though U.S. Cellular doesn’t offer any free cell phones with a signed contract, this cell phone provider states one of its key features loud on clear on its website’s homepage: “We Believe Incoming Calls Should be Free.” Incoming calls are free with U.S. Cellular’s plans, which also include free nights and weekends, as well as free mobile-to-mobile. U.S. Cellular has coverage throughout the nation, especially in major metropolitan areas. Visit their interactive coverage map here.
