T-Mobile (NASDAQ: TMUS) has expanded its T-Satellite partnership with Starlink to deliver satellite-powered app connectivity to more smartphones across the U.S., enabling popular services like WhatsApp, X, AccuWeather, AllTrails, and more to operate even without a cellular signal. The announcement marks a major leap just two months after T-Satellite's commercial debut with messaging and text-to-911 features.
"Now we're taking it up a notch and bringing essential phone apps and services into the mix - giving people access to the apps they need most, in places they've never had a signal before. It's a game-changer for safety, peace of mind, and the freedom to stay connected virtually anywhere," said Mike Katz, President of Marketing, Innovation and Experience at T-Mobile.
The update brings new functionality to a broad range of devices. For consumers, T-Satellite now supports apps for mapping, weather, messaging, and social media, including Google Messages, Pixel Weather, Apple Music, and Samsung Weather. Users can share photos, videos, voice memos, and live location data directly through supported apps.
Key third-party partners include AllTrails, AccuWeather, CalTopo, and onX, all of which now integrate T-Satellite for navigation and real-time updates in remote areas. Apps such as X (formerly Twitter) and WhatsApp allow text, image, and video communication over satellite links, supporting group chats and live video calls in regions far beyond terrestrial tower coverage.
On the enterprise side, T-Mobile has launched T-Satellite with Data for Businesses, offering resilient satellite connectivity across Android and iOS for field operations, emergency response, and remote workforces. Among the first enterprise partners are Dialpad, FLORIAN, MultiLine, and T-Mobile Direct Connect, each now supporting voice and data functions over satellite for use in outages or disaster scenarios.
The company's T-Life app now acts as a central hub for satellite-ready services, helping users manage connectivity, locate compatible apps, and contact support directly. Once activated, phones connect automatically to satellite coverage when out of range, with no user configuration required.
T-Satellite data is included with select T-Mobile plans and available as a $10/month add-on for other carriers' customers. The feature works with most satellite-capable smartphones running Android 16 or iOS 26, with additional devices expected to follow.
By merging terrestrial and orbital connectivity, T-Mobile and Starlink aim to redefine what "no signal" means - connecting people, businesses, and developers to critical services virtually anywhere with a clear view of the sky.
