Overview

• The update moves T-Satellite beyond texting by enabling a curated set of native and third‑party services to function when phones lose terrestrial signal.
• Supported titles include Google Maps, WhatsApp, X, AllTrails, AccuWeather, CalTopo, onX and T-Mobile’s T-Life, with native options like Google Messages, Apple Music and Samsung Weather also optimized.
• Connections auto‑switch to satellite and deliver critical, low‑bandwidth experiences rather than full data-heavy functionality.
• Voice and video calling over satellite are currently available primarily through WhatsApp, with T-Mobile urging more developers to adopt the SAT mode framework.
• Access is included with T-Mobile’s Experience Beyond plan, with a $10 per month add‑on available for other users, including non‑T‑Mobile subscribers.
