About United States Cellular CORP

United States Cellular Corp. (UScellular), listed on the NYSE in the United States under ticker USM, is a long-established wireless telecommunications company headquartered in Chicago, Illinois. Founded in 1983, the company built its franchise as a regional full-service mobile carrier focused on network quality, broad coverage, and a local-service proposition for consumers, businesses, and public-sector customers. Over time, it positioned itself as the fourth-largest full-service wireless carrier in the United States, emphasizing reliable connectivity and customer experience. ([newsroom.uscellular.com](https://newsroom.uscellular.com/uscellular-company-information-and-facts/?utm_source=openai)) Historically, UScellular’s core business consisted of postpaid and prepaid voice, data, and messaging services, along with home and business high-speed internet, international calling, IoT solutions, and enterprise offerings such as fleet management, mobile security, push-to-talk, and priority/preemption services. Its 2024 annual report stated that the company served 4.4 million retail connections across portions of 21 states, covering a total population of about 33 million. The company also owned a tower portfolio and leased space on its towers to third-party carriers, creating a separate infrastructure revenue stream.

Its differentiation was based on network reliability, local market presence, and a portfolio of services tailored to customers outside the largest metropolitan areas. Company materials highlighted a strong, reliable network supported by newer technologies and a broad service set designed to improve consumer convenience and business productivity. ([newsroom.uscellular.com](https://newsroom.uscellular.com/uscellular-company-information-and-facts/?utm_source=openai)) The key recent development is transformative: in 2025, UScellular announced and then completed the sale of its wireless operations and selected spectrum assets to T-Mobile US on August 1, 2025, in a transaction valued at approximately $4.3 billion in cash plus assumed debt. Following closing, the company indicated it would rebrand as Array Digital Infrastructure and focus on its remaining tower assets and other residual holdings, including more than 4,400 owned towers. For investors, that means the equity story has shifted materially from a wireless operator to a more infrastructure-centric asset base.
