T-Mobile Set to Launch Satellite-Based Data Service in October

T-Mobile US plans to launch a data service on a satellite-based network in October. The company specializes in mobile telecommunication services, with 129.5 million subscribers at the end of 2024. The service will be marketed through retail outlets, websites, and mobile applications under the T-Mobile, Metro by T-Mobile, and Mint Mobile brands.

T-Mobile US, one of the largest mobile telecommunication companies in the United States, has announced plans to launch a satellite-based data service in October. This initiative aims to provide cellular data support for select third-party apps in areas with poor or no cellular coverage. The service, known as T-Satellite, will initially be available in a select group of third-party apps, including WhatsApp, X, AccuWeather, and AllTrails [1].

T-Mobile's T-Satellite service has been in beta since January 2025, with over 1.8 million users signing up to test the service. The beta period has seen the service support SMS and MMS messages, with plans to expand to voice and video calls in the future. The service will officially launch on July 23, 2025, and will include MMS support for Android phones initially, with iPhone support to follow later [1].

Starting on October 1, 2025, the T-Satellite service will offer data support for select third-party apps, allowing users in cellular dead zones to connect to SpaceX’s orbiting satellites. The list of supported apps is expected to grow over time, with the carrier actively recruiting app developers to optimize their apps for satellite data [1].

The cost of the T-Satellite service will be $10 per month for users on T-Mobile and other carriers, including AT&T and Verizon. T-Mobile subscribers on the Experience Beyond plan will receive the satellite feature as a free perk. Additionally, the service will be free for emergency uses, including 911 texting for any mobile customer with a compatible device, regardless of carrier or subscription [1].

T-Mobile's move into satellite-based data services comes amidst a broader trend of companies leveraging satellite technology for improved connectivity. For instance, SpaceX's Starlink service has been gaining traction for its high-speed internet capabilities in rural and remote areas [1].
