The launch of this service follows substantial technical and regulatory advancements, particularly after the deployment of the first Direct to Cell satellites in early 2024.

In the past year, SpaceX has launched over 400 satellites to enhance the Direct to Cell network, facilitating millions of messages during beta testing and emergency scenarios.

Technical achievements include successful SMS tests, video calls on platforms like X and WhatsApp, and data testing of IoT devices within just nine days of the initial satellite launch.

SpaceX has collaborated with T-Mobile to provide satellite messaging services during emergencies, effectively supporting communication during events like Hurricanes Helene and Milton and the Los Angeles wildfires.

A key milestone was achieved in November 2024 when SpaceX received FCC approval for commercial service in the U.S., marking a significant step for satellite-to-mobile connectivity.

As of mid-February 2025, the Starlink Direct to Cell messaging service is operational in the United States and New Zealand, with additional country expansions planned throughout the year.

Currently, Starlink is testing services with operator partners in countries such as Australia, Canada, Chile, and Japan, with plans for further expansion in 2025 to include nations like Ukraine and Switzerland.

Starlink's Direct to Cell service enables 4G LTE mobile phones to send messages via satellites, significantly extending connectivity to areas previously deemed unreachable.

This innovative network aims to provide global connectivity by eliminating mobile dead zones through advanced satellite-to-mobile technology.

The service utilizes satellites that act as cell towers in space, effectively addressing challenges such as doppler shift, latency, and low antenna gain.
