US carriers form satellite venture to tackle mobile dead zones

Engadget ·

AT&T, T-Mobile and Verizon have formed a joint venture to use satellites to improve mobile coverage in US areas where ground-based networks are limited. The plan aims to reduce dead zones and provide connectivity during emergencies, while making satellite services easier to access across providers.

The venture, first announced in May, will be overseen by a board with representatives from each company and has appointed interim CEO Paul Roth. The companies say it could “nearly eliminate” US areas without mobile service and improve network performance, but have not given a launch date. The partnership may also help them compete with satellite mobile services such as Starlink and Amazon Leo.

  • Three US mobile networks are joining forces on satellite coverage.
  • The venture aims to reduce dead zones and aid emergency connectivity.
  • No launch date has been announced.

Mobile phone networks in the United States depend on ground-based transmitters and towers. Rural regions, mountains and remote areas often lack this infrastructure, leaving residents without reliable mobile coverage. Satellites can provide connectivity to places where building ground networks would be too expensive or impractical.

Three of the largest mobile carriers in the United States—AT&T, T-Mobile and Verizon—have formed a joint venture to develop satellite mobile services. Announced in May, the partnership aims to fill coverage gaps and provide backup connectivity during emergencies when ground networks are damaged or fail. Paul Roth is the interim chief executive, with each company represented on the board.

The venture addresses connectivity gaps affecting millions of Americans in underserved areas. It also reflects growing competition in satellite communications, as companies like Starlink and Amazon are launching their own satellite mobile services. This coordinated industry effort represents one approach to extending mobile coverage across the country.

Both sides, in good faith

The strongest fair case each way — we don't pick a winner.

The case for

The venture addresses a genuine infrastructure gap: substantial portions of rural and remote America lack reliable mobile coverage, creating documented harms for emergency response and economic development. Satellite technology is economically rational where ground infrastructure remains unviable, and pooling resources between the carriers enables faster, more cost-effective deployment. The commitment to interoperability across providers is genuinely pro-consumer and particularly valuable for emergency communications. Competition with Starlink and Amazon's ventures represents normal market dynamics rather than anti-competitive behaviour.

The case against

The coordination of America's three largest mobile carriers on a transformational technology raises legitimate concerns about market concentration and reduced competitive pressure on incumbents. Without rigorous independent oversight, the venture's vague timelines and lack of binding deployment commitments suggest the companies' primary motivation may be defensive positioning against disruptive satellite competitors rather than genuinely serving underserved communities. There is substantive risk that consolidated control of satellite mobile services will entrench established players' market power and reduce consumer choice, particularly if pricing and coverage decisions prioritise profitability over public need.
