Array Digital Infrastructure (Formerly known as United States Cellular Corporation aka UScellular) is an American shared wireless communications infrastructure manager and former mobile network operator. As UScellular, its stock was publicly traded, but Telephone and Data Systems Inc. owned a controlling stake (83% economic and 96% voting power). The company was formed in 1983 and was headquartered in Chicago, Illinois. UScellular was the fifth largest wireless carrier in the United States, with 4.4 million subscribers in 21 states as of March 31, 2025.
In May 2024, T-Mobile US announced it would acquire UScellular's wireless customers and retail outlets, plus 30% of its wireless spectrum licenses in a deal worth $4.4 billion. The deal closed on August 1, 2025; currently known as "USCellular, now a part of T-Mobile", customers and stores will eventually be transitioned to T-Mobile. In addition to the T-Mobile deal, UScellular announced that it had reached agreements to sell 55% of its remaining wireless spectrum license holdings for approximately $1 billion to AT&T and $1 billion to Verizon.
