AT&T, T-Mobile, and Verizon have launched a joint venture to expand wireless coverage in underserved U.S. areas by pooling spectrum resources and shared infrastructure investment. Paul Roth, an industry veteran who previously led operations at AT&T, Cingular Wireless, and Ameritech, will serve as interim CEO during the search for a permanent leader.
The venture formalizes a commitment first announced in May. A board of representatives from each carrier will oversee operations, and existing carrier-satellite agreements will remain active, allowing each company to pursue independent connectivity initiatives alongside the JV.
The economics are straightforward: instead of three parallel infrastructure builds in areas where terrestrial networks struggle, a consolidated approach reduces per-carrier capital requirements while expanding collective reach. This capital allocation decision trades some autonomy for operational efficiency in low-density regions where deployment costs per subscriber are highest.
The venture strengthens the competitive moat of all three carriers by improving coverage ubiquity—a metric consumers and enterprise customers track closely. For incumbents with existing scale, better coverage in marginal areas raises barriers for smaller competitors or new market entrants that would struggle to finance comparable network density.
AT&T operates over 100 million consumer lines and 2.5 million business connections. T-Mobile US, headquartered in Bellevue, Washington, operates a 5G network across its T-Mobile, Metro by T-Mobile, and Mint Mobile brands. Verizon Communications, based in New York City, reported $138.2 billion in 2025 revenue and serves most of the Fortune 500.
