Overview

• Messages, Maps, Weather, Music, Fitness, and Compass now operate in satellite-friendly modes when no cellular or Wi‑Fi signal is available.
• Apple shows a SAT indicator when the phone is using a carrier-provided satellite link, and supported apps run in stripped-down, low-bandwidth configurations.
• T-Mobile says broader limited data connectivity for satellite apps will be enabled on October 1 as part of a staged rollout.
• The service works on iPhone 13 and newer models and can be added via eSIM to unlocked devices without switching from AT&T or Verizon.
• T-Satellite moved from a free beta to a July launch at $10 per month, with inclusion on select premium plans, and T-Mobile is working with developers to expand supported apps over time.
