- Telephone and Data Systems, Inc., a diversified telecommunications entity, provides a range of communication and infrastructure services across the United States. The company's operations are primarily conducted through two main segments: TDS Telecom and Array Digital Infrastructure. TDS Telecom delivers advanced broadband, video, and voice solutions to residential and business customers in a mix of urban, suburban, and rural communities. Its offerings include high-speed internet, powered by fiber optics, capable of speeds up to 8 Gigabit, alongside comprehensive Wi-Fi services. The segment also provides an integrated cloud television platform, TDS TV+, as well as traditional local and long-distance telephone services, Voice over IP (VoIP), and enhanced communication features. For businesses, TDS Telecom extends dedicated internet, IP-based services, hosted voice, and video collaboration tools. Additionally, as of late 2025, TDS Telecom introduced TDS Mobile, a mobile virtual network operator (MVNO) service, providing nationwide 5G coverage with unlimited talk and text options exclusively for its broadband clientele. The Array Digital Infrastructure segment, which evolved from the former UScellular wireless operations after a significant divestiture in 2025, now concentrates on managing and leasing wireless tower space to third-party carriers. Telephone and Data Systems facilitates sales and distribution through a variety of channels, including direct and indirect sales, retail locations, third-party agents, e-commerce platforms, and telesales. The company has demonstrated a strategic shift towards expanding its fiber footprint, with a target of 1.8 million fiber addresses, actively connecting underserved areas with high-speed internet. The company was established in 1969 and maintains its headquarters in Chicago, Illinois. Telephone and Data Systems also issues dividends on its common and preferred shares.
