Amazon details Leo direct-to-phone plan

Amazon has submitted a request to the U.S. Federal Communications Commission seeking authorization to deploy a direct-to-device satellite network as part of its Leo project. The planned system is intended to provide mobile services directly to smartphones and other mobile devices without relying solely on terrestrial cell towers. The filing describes a low-Earth-orbit constellation sized at roughly 5,000 satellites to support the new offering.

The proposed network is designed to support messaging, voice, data and emergency services for compatible smartphones. By linking directly from space to ordinary mobile devices, the system aims to extend connectivity into areas that lack conventional cellular coverage. The initiative positions the Leo project not only as a broadband platform but also as a provider of mobile connectivity from orbit.

The direct-to-device network is structured to deliver a range of services similar to terrestrial mobile networks, including two-way messaging, voice calls and data connectivity. A key focus is the ability to maintain communications in remote or underserved regions where building or maintaining cell towers is difficult. Emergency services are also part of the design, enabling users to reach assistance even when local infrastructure is unavailable.

The constellation’s global coverage ambitions are supported by its scale, with plans for around 5,000 low-Earth-orbit satellites. Operating closer to Earth than traditional geostationary satellites, these spacecraft are intended to improve signal strength and latency for direct links to smartphones. The filing frames the system as an overlay to existing mobile networks, filling gaps rather than replacing terrestrial infrastructure.

Amazon has stated that more than 390 Leo satellites are already in orbit. The company considers this number sufficient to support the start of "initial service" later in 2026. This early phase is expected to leverage the existing spacecraft while additional satellites are launched to build out the full constellation for direct-to-device coverage.

The current satellites represent the first wave of the broader Leo architecture that will underpin both broadband and direct-to-phone services. As more satellites are deployed, the network is intended to increase geographic coverage and service quality. The filing signals that the direct-to-device capability is a central element of the future expansion of the Leo system.

By pursuing a large direct-to-device constellation, Amazon is aligning its satellite strategy with growing demand for connectivity beyond the reach of traditional networks. The combination of mobile-style services and satellite coverage aims to keep users connected across a wide range of environments, including rural and remote regions. The focus on emergency communication underscores the potential role of the Leo network in resilience and safety use cases.

The FCC filing marks a significant step in defining the technical and operational parameters of Amazon’s satellite-to-phone ambitions. With a substantial number of satellites already in orbit and plans for thousands more, the Leo project is being positioned as a major new platform for space-based mobile services. How quickly the constellation scales from initial service to broad direct-to-device coverage will shape the network’s impact on the mobile connectivity landscape.
