United States Cellular Corporation operates as a wireless telecommunications company primarily serving retail customers and businesses across the United States. The company offers wireless voice and data services, smartphone devices, wireless accessories, and related products under its UScellular brand. Its product portfolio includes wireless plans, postpaid and prepaid services, and devices such as smartphones, tablets, and mobile broadband equipment. UScellular operates a 5G and LTE network across 21 states, providing coverage to approximately 4.4 million retail connections.
Founded in 1983 and headquartered in Chicago, Illinois, United States Cellular Corporation focuses on mid-sized markets with extensive network infrastructure investments. The company has expanded its offerings with recent enhancements in 5G fixed wireless service and partnerships aimed at improving customer digital experiences, notably through collaborations with technology providers like Samsung for 5G mmWave and vRAN solutions.
Significant recent developments include the sale of its wireless operations to T-Mobile US, completed in August 2025, for $4.3 billion, involving both cash and assumed debt. Following this transaction, United States Cellular has repositioned itself primarily as a digital infrastructure company retaining ownership of approximately 4,400 wireless towers, positioning it as the fifth-largest tower operator in the United States. It entered into a 15-year Master License Agreement with T-Mobile and has spectrum license sales agreements pending with major operators such as Verizon and AT&T. The company also anticipates distributing a substantial special cash dividend to shareholders post-sale. The leadership transition includes the appointment of Douglas W. Chambers as interim President and CEO to oversee the tower portfolio, noncontrolling investments, and retained spectrum assets.
Overall, United States Cellular Corporation has shifted its business model from a traditional wireless carrier to a digital infrastructure and asset management company following its divestiture of consumer wireless operations, maintaining a strategic role in the telecommunications ecosystem. It continues to operate under the broader ownership of Telephone and Data Systems, Inc. (TDS).
