T-Mobile announced on Wednesday that its satellite-to-cell network—developed in partnership with SpaceX’s Starlink—now supports popular apps such as WhatsApp, Google Maps, and X, expanding mobile connectivity for users in dead zones and remote regions.
The service, known as T-Satellite, initially launched commercially in July 2024 with limited capabilities, allowing only SMS texting, MMS, photo messages, and short audio clips when users were outside the range of traditional mobile networks.
Now, T-Mobile says the system can support a dozen widely used apps, including Apple Music, Samsung Find, Pixel Weather, AccuWeather, and AllTrails, alongside its new flagship “Experience Beyond” plan.
“We’ve worked closely with Apple and Google to create frameworks for SAT mode so that any app can access the data channel when connected to the satellite,” said Jeff Giard, T-Mobile’s Vice President of Strategic Partnerships and Product Innovation, in an interview with Reuters.
HOW IT WORKS
The network relies on more than 650 Starlink direct-to-cell satellites, which automatically connect when a user’s device loses a terrestrial signal.
Apps that are “satellite-ready” provide essential services such as navigation, communication, and weather updates — though not full, data-heavy features like high-definition video streaming.
T-Mobile customers under the Experience Beyond plan can access the network at no extra charge, while users from AT&T and Verizon can subscribe for $10 per month.
EXPANDING DEVELOPER ACCESS
Giard said that both the App Store and Google Play Store now support SAT mode integration through a dedicated API, enabling developers to make their apps satellite-compatible.
T-Mobile is working with app makers to encourage adoption, especially for tools that provide critical communications and safety features.
“People are excited that their regular phone can now connect to space,” Giard said. “They essentially get a satellite phone experience—without having to buy new equipment.”
With this expansion, T-Mobile strengthens its push toward universal mobile connectivity, aiming to make complete coverage a reality even in the world’s most remote areas.
