T-Mobile US Adds Satellite Support for WhatsApp and X

T-Mobile US expanded its satellite-to-cell network to support a wider range of popular mobile apps. The coverage now includes WhatsApp and X, as the company looks to extend connectivity to mobile dead zones and remote areas.

T-Satellite launched commercially in July with text messaging, short audio and picture messages, and emergency text-to-911. With the upgrade, the service is now compatible with around a dozen mobile applications, including WhatsApp, Apple Music, AccuWeather, Google Maps, X, and T-Mobile’s own T-Life app. The expanded service is built to provide essential data services when traditional mobile networks are out of reach, with connectivity powered by more than 650 of SpaceX’s Starlink direct-to-cell satellites.

The operator is also extending T-Satellite into enterprise services, unlocking new business use cases and targeting industries that require persistent off-grid communication. It will support business apps such as Florian, designed for private sector industries such as hospitality and logistics, and MultiLine, which supports government, healthcare, and other regulated sectors.

The enhanced service is available on most satellite-capable devices running Android 16 or iOS 26, with more platforms to follow. According to T-Mobile, as with messages and emergency notifications, the phone will automatically shift to satellite connectivity when the cellular signal drops, enabling customers to use a satellite-ready app.
