U.S. Cellular to blanket a quarter of its network with LTE by year's end
Mary N. Dillon, Chairman and CEO of the carrier, said, "With 4G LTE, our customers will have faster connections to the people, information and entertainment that enhance their lives and help them stay organized. In addition to our line-up of cutting-edge devices, customers who switch to U.S. Cellular get unique benefits like faster phone upgrades without continuously signing contracts, and join the happiest customers in wireless."
The carrier added that it will continue to build its 4G network during 2012 and will make an announcement of the roll out at a later date.
