Staying Connected When the Cell Towers Are Down: A Guide to Satellite Texting


This informal guide covers how to use these life-saving features on an iPhone, with a brief look at similar options for Android below.

When severe weather or power outages take down local cell towers and Wi-Fi, modern smartphones can now act as satellite
communicators. This means you can bypass the cell network entirely by pointing your phone at satellites orbiting in space. https://support.apple.com/en-us/105097#:~:text=Satellite%20features%20on%20iPhone,family%2C%20and%20share%20your%20location.

1. Reaching First Responders (Emergency SOS)

If you are in a life-threatening situation (such as a medical emergency or severe accident) and have no cell service, your iPhone can contact 911 dispatchers directly. https://mashable.com/article/apple-emergencysos-via-satellite-iphone-14-nowlive#:~:text=Emergency%20SOS%20on%20iPhone%3A%20How,emergency%20services%20through%20your%20iPhone.

2. Contacting Loved Ones (Messages via Satellite)

You don’t have to be in a 911-level emergency to use the satellite. If you just need to tell your family you are safe after a storm, you can send standard text messages. https://support.apple.com/en-us/105097#:~:text=Satellite%20features%20on%20iPhone,family%2C%20and%20share%20your%20location.

  • Who has this capability: You need an iPhone 14, 15, 16 or 17, and your phone must be updated to iOS 18 or newer.
  • How to use it: When your phone loses all cell and Wi-Fi service, open your normal Messages app. A prompt will appear at the top of the screen offering to use the satellite connection.
  • What happens next: The phone will guide you to point your device toward a satellite. Once connected, you can text your friends and family.
  • Keep in mind: Satellite signals travel a long way and are much slower than regular cell service. A short text may take a minute or more to send. You cannot send photos, videos, or group texts—only words and emojis

How to Practice Safely (The Connection Demo)

The best time to learn how to connect to a satellite is before an emergency happens. Apple includes a risk-free “Demo Mode” that lets you practice aiming your phone at a real satellite without actually calling 911. https://mashable.com/article/apple-emergency-sos-via-satellite-iphone-14-now-live#:~:text=The%20demo%20will%20temporarily%20disable,and%20receive%20messages%20via%20satellite.

1.Step Outside:

You must be outdoors with a clear view of the sky. Trees, tall buildings, and roofs will block the satellite signal.

2.Open the Control Center:

Swipe down from the very top-right corner of your iPhone screen.

3.Tap the Cellular Icon:

Look for the button with the antenna icon on the right side of the Control Center and tap it.

4.Select Satellite:

Tap the Satellite option, then select Try Demo. (Note: This will temporarily turn off your cell service and Wi-Fi to simulate a power outage).

5.Follow the On-Screen Tracker:

The screen will show a radar graphic. Simply turn your body left or right as the arrows instruct until your phone connects with a satellite passing overhead.

Once you are done practicing, you can exit the demo, and your normal phone service will immediately return.

What About Android Phones?

Android devices also offer satellite connections, though the method depends on the phone you have: https://www.att.com/device-support/article/wireless/000107337/Google/GoogleGGX8B
