AT&T, T-Mobile and Verizon have entered into a joint venture agreement aimed at expanding mobile coverage across underserved areas of the United States and accelerating the development of satellite-based connectivity.
The initiative builds on plans announced in May 2026 to pool limited spectrum resources to reduce mobile coverage “dead zones” and extend satellite connectivity to customers nationwide. The collaboration could become an important platform for direct-to-device (D2D) satellite communications, particularly in locations where conventional cellular infrastructure cannot provide reliable coverage.
Joint Venture Targets U.S. Mobile Dead Zones
The three U.S. telecom operators will continue operating their terrestrial mobile networks independently. The joint venture is designed to complement those networks by extending connectivity into areas where building conventional cell sites is difficult or uneconomic.
One major objective is to nearly eliminate U.S. areas that currently lack mobile service. Satellite connectivity could also provide additional network resilience during hurricanes, wildfires, floods and other disasters that disrupt terrestrial infrastructure.
The companies expect their combined investment to improve access to satellite-to-smartphone services, allowing consumers to receive connectivity beyond the traditional cellular footprint.
Direct-to-Device Satellite Competition Set to Increase
A major focus will be improving D2D access while creating opportunities for additional satellite providers to compete for mobile connectivity business.
The joint venture plans to establish common technical specifications that could simplify integration between satellite networks, mobile operators, smartphones and applications. A standards-based approach involving operating-system providers, app developers and device manufacturers could also improve compatibility across satellite services.
Rural mobile network operators are expected to benefit from the platform by gaining opportunities to introduce new connectivity products without independently developing complex satellite integrations.
Spectrum Efficiency Becomes Strategic Priority
AT&T, T-Mobile and Verizon also aim to improve the utilization of scarce nationally licensed spectrum. Pooling limited spectrum resources for satellite applications could extend the reach of existing wireless assets into locations that terrestrial networks cannot economically serve.
Paul Roth has been appointed interim CEO while the venture searches for a permanent chief executive. Roth previously held senior leadership positions at AT&T, Cingular Wireless and Ameritech. The venture will be overseen by a board containing representatives from each founding company.
Importantly, existing carrier-satellite agreements will remain intact. AT&T, T-Mobile and Verizon will also retain the ability to pursue independent satellite connectivity initiatives, potentially creating multiple paths toward broader satellite-enabled mobile coverage across the United States.
