AT&T and AST SpaceMobile Push Forward with Satellite-to-Cell Technology

AT&T is making strides in its partnership with AST SpaceMobile to bring satellite connectivity directly to everyday smartphones, aiming to provide coverage in areas beyond the reach of traditional cell towers. This move positions AT&T as a competitor to T-Mobile, which already offers a similar service through SpaceX’s Starlink, and Verizon, which has also partnered with AST SpaceMobile.

Expanding Coverage with Satellite Technology

The collaboration between AT&T and AST SpaceMobile, formalized with a commercial agreement extending to 2030, focuses on establishing a space-based broadband network accessible via standard cell phones. Users will only need a clear view of the sky to connect. AT&T has been working with AST SpaceMobile since 2018, investing $110 million alongside companies like Google in January 2024 [1].

BlueBird Satellites and Enhanced Capabilities

AST SpaceMobile recently handed over its BlueBird 7 (BB7) satellites to Blue Origin for launch into Low Earth Orbit (LEO). These satellites are equipped with a denser antenna array than competitors, promising broader coverage, improved connectivity, and faster speeds. AST claims peak data rates of up to 120 Mbps, exceeding the speeds currently offered by T-Mobile’s satellite service [1].

Progress and Challenges

While AT&T aims to match or surpass T-Mobile’s satellite service with fewer satellites, AST SpaceMobile has faced challenges in meeting its launch targets. The company initially planned five launches in the first quarter of 2026 but has only completed one BlueBird 6 satellite launch to date [2]. Satellite analyst Tim Farrar expresses skepticism about AST’s ability to deliver continuous service across the US this year.

First Successful VoLTE Call and SMS

In July 2025, AT&T and AST SpaceMobile achieved a significant milestone by completing the first native voice call (VoLTE) and text message (SMS) over AST’s Block 1 satellites, using a standard, unmodified cell phone on AT&T’s spectrum and core network [4]. This demonstrated the potential for expanding mobile service to remote and underserved areas without requiring specialized hardware.

Competition and Partnerships

The satellite-to-cell technology space is becoming increasingly competitive. T-Mobile is currently beta testing a similar service with SpaceX’s Starlink, and Verizon has also entered into an agreement to utilize AST SpaceMobile’s network via 850 MHz low-band spectrum [2]. AST SpaceMobile has secured partnerships with over 50 mobile network operators globally [2].

Looking Ahead

AT&T plans to launch a beta program for its satellite service in the first half of 2026, though a commercial rollout timeline remains uncertain. The company is actively building the necessary infrastructure, including ground gateways to connect the satellites to its network. The success of this venture will depend on AST SpaceMobile’s ability to consistently launch satellites and deliver on its promises of enhanced speed and coverage.
