SHERIDAN, WYOMING – March 4, 2025 – Deutsche Telekom and Google have announced a significant milestone in satellite communication technology, successfully testing SMS over satellite on a commercial Google Pixel 9 smartphone. This marks Europe's first Direct-to-Handset (D2H) SMS transmission via GEO satellite to a consumer device.
Successful Test in Greece Demonstrates Real-World Application
The test, conducted by Deutsche Telekom with its subsidiary Cosmote in Greece, involved sending and receiving Peer-to-Peer (P2P) SMS messages from an area lacking terrestrial network coverage. This achievement builds upon their November 2024 demonstration using a testing device, now showcasing the capability on a widely available commercial smartphone. This advancement is a critical step towards deploying publicly accessible satellite communication services.
Commercial Launch Targeted for Late 2025
Deutsche Telekom aims to launch the first commercial Direct-to-Handset messaging services in Germany and Europe by the end of 2025. This timeline aligns with the increasing availability of smartphones equipped to support satellite communication.
Expanding Connectivity to Remote and Emergency Scenarios
Direct-to-Handset services will enable users to connect to satellites for text messaging in remote areas without terrestrial network access. This technology also holds significant potential for emergency communications and disaster response when traditional networks are unavailable.
Executive Insights on the Breakthrough
"Staying connected is not just a convenience – it is a necessity. Successfully demonstrating SMS via satellite on a Google Pixel 9 commercial smartphone marks a crucial step towards ensuring our customers have seamless communication whenever they go. This Direct-to-Handset breakthrough brings us closer to a future where connectivity knows no boundaries, keeping people informed, empowered and always within reach” said Antje Williams, responsible for satellite communication at Deutsche Telekom.
"Google believes that connectivity should be accessible to everyone, everywhere, and Direct-to-Handset services are opening up exciting opportunities. We've already shown the potential with Satellite SOS on the Pixel 9, allowing emergency satellite communication when cellular and Wi-Fi are not available. We're now focused on bringing these benefits to more customers and exploring even more innovative use cases with our partners around the world” said Aamir Akram, Senior Director of Global Carrier Engineering at Google.
Technical Details of the Satellite SMS Transmission
The SMS transmission utilized a Google Pixel 9 with a Cosmote SIM card, directly connecting to Skylo’s satellite service via dedicated licensed Mobile Satellite Spectrum (MSS). The integration adheres to the 3GPP Release 17 specifications for Direct-to-Handset (D2H) connectivity, based on industry standards and designed for operator-native use. This approach integrates a non-terrestrial network into the terrestrial mobile operator’s production network, ensuring seamless coverage regardless of location.
Future Implications and Consumer Benefits
This successful test signifies a major leap forward in bridging connectivity gaps, particularly for those in remote regions and during emergencies. As satellite-enabled smartphones become more prevalent, consumers can expect enhanced communication capabilities, ensuring they remain connected no matter where they are. The collaboration between Deutsche Telekom and Google highlights the ongoing innovation in the telecommunications sector, pushing the boundaries of what is possible in mobile connectivity.
