U.S. Cellular, now known as Array Digital Infrastructure, is a telecommunications company that has undergone significant transformations in recent years. Founded in 1983 and headquartered in Chicago, Illinois, the company initially operated as a wireless carrier, providing voice, data, and internet services to approximately 4.4 million subscribers across 21 states.

In May 2024, T-Mobile US announced its intention to acquire U.S. Cellular's wireless operations, including its customer base and retail outlets, in a deal valued at $4.4 billion. The acquisition was completed on August 1, 2025, marking a significant shift in the company's business model.

Following the acquisition, U.S. Cellular rebranded itself as Array Digital Infrastructure, focusing on managing shared wireless communications infrastructure. The company now specializes in:

Providing wireless spectrum licenses
Tower leasing services to other carriers including T-Mobile US, AT&T, and Verizon

This strategic pivot allows Array Digital Infrastructure to leverage its existing assets and expertise in wireless infrastructure while reducing direct competition in the consumer wireless market.

Array Digital Infrastructure's portfolio includes a substantial number of wireless spectrum licenses and tower assets, which it leases to various telecommunications providers. By offering these infrastructure services, the company plays a crucial role in supporting the expansion and enhancement of wireless networks across the United States.

Headquarters and Locations

The company's headquarters remain in Chicago, Illinois. It also has a primary location in:

Milwaukee, WI, USA

While specific details about additional office locations are not readily available, the company's extensive network of wireless infrastructure assets spans multiple states, reflecting its broad operational footprint.
