T-Mobile US expanded its satellite-to-cell network to support a wider range of popular mobile apps, including WhatsApp and X, as it looks to extend connectivity to mobile dead zones and remote areas. 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 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 cellular signal drops, enabling customers to use a satellite-ready app. Jeff Giard, VP of strategic partnerships and product innovation at T-Mobile, told Reuters the operator worked closely with Apple and Google to enable any app to adopt satellite connectivity.
