10 Tech How-To

Enable Satellite Messaging & SOS on iPhone and Android

Guide 10-13298 · Updated · Step by step

Satellite messaging and Emergency SOS let you text for help when you have no cellular or Wi-Fi coverage, using satellites overhead instead of cell towers. This guide walks you through setting up the feature on both iPhone and Android, including what to do before you need it and what to expect when you use it.

What You’ll Need

  • An iPhone 14 or later (with iOS 18 or newer) or a compatible Android phone (Google Pixel 9 series, or Samsung Galaxy S25 series).
  • An active Apple ID (for iPhone) or Google account (for Android).
  • For Android, the Satellite Messenger app (pre-installed on Pixel 9 and Galaxy S25).
  • For iPhone, the Messages app (built-in) and a compatible carrier plan (most major carriers work).
  • A clear view of the sky – no heavy tree cover or tall buildings blocking the horizon.
  • Your phone charged to at least 20% battery (the feature uses more power).

Step-by-Step (iPhone)

  1. Update iOS: Go to Settings > General > Software Update and install any available updates. Satellite messaging requires iOS 18 or later.
  2. Enable Location Services: Go to Settings > Privacy & Security > Location Services and turn it on. This is required for the satellite connection.
  3. Set Up Emergency Contacts: Open the Health app, tap your profile picture, then Medical ID. Add your emergency contacts and health information. This is what gets shared during an SOS.
  4. Test the Satellite Demo: In Settings > Satellite, tap Try Demo. This walks you through pointing your phone at a satellite without actually connecting. Do this when you have signal.
  5. Use Satellite Messaging: When you have no cellular signal, open the Messages app. You’ll see an option to “Use Satellite� when you try to send a message. Tap it and follow the on-screen prompts to connect to a satellite.
  6. Trigger Emergency SOS: Press and hold the side button and one volume button until the Emergency SOS slider appears. Drag the slider, then choose Emergency SOS via Satellite. If you’re in a supported region, the phone will guide you to point at a satellite and connect.

Step-by-Step (Android)

  1. Check Compatibility: Satellite messaging is available on Google Pixel 9 series and Samsung Galaxy S25 series (and later models). If you have an older phone, this feature won’t work.
  2. Update Software: Go to Settings > System > Software update and install any pending updates. Both Pixel and Samsung phones need the latest Android version.
  3. Open the Satellite Messenger App: On Pixel 9, it’s pre-installed. On Galaxy S25, find it in the app drawer. If it’s not there, check the Play Store for updates.
  4. Sign In: Use your Google account to sign in. You’ll need to grant permissions for location, contacts, and phone.
  5. Set Up Emergency Contacts: In the app, go to Settings > Emergency contacts and add at least one contact. This is who gets your SOS messages.
  6. Use Satellite Messaging: When you’re out of range, open the Satellite Messenger app. It will show a “Connect to satellite� button. Tap it and follow the prompts to point your phone at the sky.
  7. Send an SOS: In the app, tap the SOS button. You’ll select your emergency contacts, then the app will guide you through connecting and sending your message with your location.

Common Mistakes

  • Not having a clear view of the sky: Satellite connections need a direct line of sight. Trees, buildings, or even heavy clouds can block the signal.
  • Pointing the phone wrong: The phone’s screen shows a radar-like indicator. You must physically move your phone to align with the satellite – not just rotate it.
  • Forgetting to set up emergency contacts: If you haven’t added contacts in Health or the Satellite app, you can’t send an SOS to anyone.
  • Expecting it to work like regular texting: Satellite messages are limited to plain text (no photos or videos) and can take 30 seconds to a few minutes to send.
  • Using an unsupported phone: Satellite messaging is not available on older models, even if they have the latest software.

Tips

  • Practice the demo: iPhone’s “Try Demo� and the Android app’s tutorial mode let you practice connecting without using your emergency service. Do this before you need it.
  • Keep your phone charged: Satellite connections drain battery faster. Carry a power bank if you’re going off-grid.
  • Move to higher ground: If you’re in a valley or dense forest, walk to a clearing or uphill to improve your chances of connecting.
  • Stay still while connected: Once you’re connected, keep your phone pointed at the satellite until the message sends.
  • Use it for check-ins too: On iPhone, you can share your location via satellite with friends and family, not just during emergencies. Android’s app also allows non-emergency check-ins.

Troubleshooting

  • No satellite option appears: Make sure you’re truly out of cellular range – the option only appears when there’s no signal. Also check that your phone is compatible and software is up to date.
  • Can’t connect to satellite: Move to an open area, away from trees and buildings. Wait a few minutes – satellites move, so the connection point changes.
  • Messages won’t send: Check that you’ve selected the right satellite (the phone usually does this automatically). If it fails, try again after 30 seconds. On iPhone, you may need to re-enter the satellite menu.
  • Emergency SOS says “not available�: This can happen if you’re in a region where satellite SOS isn’t supported, or if your carrier doesn’t support it. Check Apple’s or Google’s coverage maps.
  • Android app crashes: Clear the app cache in Settings > Apps > Satellite Messenger > Storage, then restart the app. If it persists, reinstall the app.
  • Battery drains fast: Satellite connections are power-hungry. Close other apps, lower screen brightness, and put the phone in battery saver mode while using satellite features.

Frequently Asked Questions

Is satellite messaging free?

Yes, both Apple and Google currently offer satellite messaging at no extra charge. Apple includes it free for two years with iPhone 14 and later; Google includes it free on Pixel 9 and Samsung Galaxy S25. After that, Apple may charge, but no pricing has been announced.

Can I use satellite messaging to text anyone, or only emergency services?

On iPhone, you can message any contact (not just emergency services) via satellite, but only if you’re in a supported region. On Android, the Satellite Messenger app allows messaging to your emergency contacts and check-ins to anyone, but only for the first few months after purchase – then it becomes SOS-only.

Does satellite messaging work internationally?

Apple’s satellite features work in the US, Canada, UK, Ireland, France, Germany, and a few other countries. Google’s satellite messaging is available in the US only (and some regions of Europe for Pixel 9). Check your manufacturer’s coverage map before relying on it abroad.

What information is sent during an Emergency SOS?

Your phone sends your location, your Medical ID (if set up), and a transcript of your conversation with emergency dispatchers. It also notifies your emergency contacts with your location and a link to your live location.

Do I need a special SIM or plan for satellite messaging?

No. Satellite messaging works with your existing SIM and carrier plan. However, your carrier must support the feature – most major carriers do, but some smaller ones may not. Check with your carrier if you’re unsure.

Can I use satellite messaging on a tablet or smartwatch?

No. Satellite messaging is currently only available on specific iPhone and Android phone models. It’s not available on iPads, Apple Watches, or other wearables.
