Overview
- The rollout adds support for WhatsApp, Google Maps, X, AllTrails, AccuWeather, CalTopo, onX and T-Mobile’s T-Life on eligible iPhone and Android devices.
- WhatsApp works for messages, photos, voice notes and supports voice and video calls, while other apps provide pared-back features designed for satellite links.
- Phones automatically switch to the satellite connection when cellular or Wi‑Fi drops, and supported apps deliver critical services rather than full data-heavy experiences.
- Access is included on T-Mobile’s top plans, and other users — including AT&T and Verizon customers — can add T‑Satellite for $10 per month.
- T-Mobile says it built SAT mode frameworks with Apple and Google to let developers enable satellite-aware behavior through an API, with more apps encouraged to join.
