How to Use a Satellite Communicator

When you’re hiking deep into the backcountry, paddling remote lakes, or road-tripping through remote terrain, staying connected isn’t just convenient—it’s potentially life-saving. Cell towers disappear quickly in rugged areas, and that’s where satellite communicator step in.

These powerful little devices allow you to send texts, track your location, receive weather updates, and call for help—anywhere on the planet. Whether you’re a solo hiker or part of a team on expedition, understanding how to use a satellite communicator is essential for safe and smart adventures.

In this blog, we’ll break down exactly how satellite communicators work, how to use them effectively, what features to look for, and some of the best models available at SunnySports.

What Is a Satellite Communicator?

A satellite communicator is a handheld device that connects to satellites instead of cellular networks. It allows you to send messages, share GPS coordinates, and in many cases, trigger an emergency SOS to a rescue service.

Unlike a satellite phone (which allows voice communication), most satellite communicators are data-based—they send text messages or location points through satellite networks like Iridium or Globalstar.

Why You Might Need One

If you’re heading off the grid, a satellite communicator is one of the most important tools in your gear kit. It’s not just for extreme adventurers—anyone going beyond reliable cell service can benefit.

Use Cases:

• Backpacking in national parks

• Boating or kayaking in remote waters

• Overlanding and road-tripping

• Climbing or mountaineering

• International travel

• Solo hiking or trail running

How Satellite Communicators Work

Satellite communicators use low Earth orbit satellites to send and receive messages or GPS signals. Depending on your device, you can:

• Send preset or custom text messages

• Share your live location with contacts

• Check-in with a “I’m okay” signal

• Request emergency help via SOS

• Download basic weather forecasts

Devices often require a subscription plan—either monthly, annually, or pay-as-you-go—to use messaging and tracking features.

Step-by-Step: How to Use a Satellite Communicator

1. Choose the Right Device

There are two main types:

• Two-way communicators: Let you send and receive texts (e.g., Garmin inReach, ZOLEO).

• One-way communicators: Send outgoing messages or SOS only (e.g., SPOT Gen4).

Choose based on your budget, communication needs, and preferred network coverage.

2. Activate Your Device and Subscription

Before hitting the trail:

• Register your device on the manufacturer’s website.

• Choose a subscription plan that fits your usage.

• Test your device in your backyard or local park to ensure it’s working.

Garmin, for example, offers flexible plans for the inReach Mini, including monthly Freedom plans or annual contracts.

3. Download the Companion App (Optional)

Most devices have companion apps for smartphones:

• Garmin Earthmate or Explore app

• ZOLEO app

• SPOT App

These allow easier texting, map viewing, weather access, and tracking from your phone (via Bluetooth).

4. Create Preset Messages

Preset messages are quick, reusable texts like:

• “I’m checking in—all good!”

• “Running late, but safe.”

• “Made camp for the night.”

Set these up before your trip to save time and avoid burning through your message quota.

5. Send a Check-in or Message

To send a message:

• Go to “Messages” or “Send” on the device or app.

• Choose a recipient from your synced contact list.

• Type your message (if allowed), or select a preset.

• Send—and wait for confirmation of delivery.

Messages are sent via satellite, so you may need a clear view of the sky—avoid thick tree cover or canyons.

6. Enable Tracking and Share Location

Many devices let you enable live tracking so loved ones can view your journey online.

• Choose your tracking interval (every 10, 30, or 60 minutes).

• Share your personalized map link with family or friends.

• Set a start and stop time to preserve battery.

This is especially useful during multi-day hikes or international travel where regular check-ins may be difficult.

7. Check the Weather

Most premium devices offer basic weather forecasts via satellite.

• Select “Weather” or “Forecast” on your device.

• Choose your location or GPS coordinates.

• Download the update (may count toward message quota).

This is incredibly helpful in remote areas where storms can roll in fast and unexpectedly.

8. Send an SOS in Case of Emergency

In a real emergency, hold the SOS button for several seconds. This sends a distress signal to a Global Emergency Response Coordination Center (like GEOS or IERCC), who will coordinate with local search and rescue.

You’ll often be able to:

• Confirm the emergency

• Communicate with rescuers (on two-way devices)

• Receive updates on ETA or status

Only use SOS for life-threatening situations. False alarms waste resources and may incur fees.

Best Practices and Safety Tips

1. Always Test Before You Go

Send a few practice messages and check tracking features. Make sure your contacts receive them.

2. Keep It Charged

Bring a power bank or solar charger on longer trips. Satellite communicators can last days, but active tracking drains battery.

3. Know the Coverage

Not all satellite networks are equal. Iridium (used by Garmin) offers global coverage, while Globalstar (used by SPOT) has limited regions.

4. Understand the Costs

Plans range from ~$11/month for minimal use to $50+ for unlimited texting. Some devices allow message bundles to save cost.

5. Store It Accessibly

Keep the communicator attached to your pack shoulder strap or hip belt—don’t bury it in your bag.

Final Thoughts

Venturing into the wilderness is exhilarating, but safety should always come first. A satellite communicator gives you peace of mind, allowing you to stay in touch, share your journey, and call for help if the unexpected happens.

They’re not just for professional adventurers—they’re for families, solo travelers, and anyone who values safety and communication when off the grid. With the right device and a little know-how, you can explore more confidently and responsibly.

So before your next off-grid trip, grab a satellite communicator from SunnySports and make smart connection part of your outdoor kit.

FAQs: How to Use a Satellite Communicator

Do I need a subscription to use a satellite communicator?

Yes. Most features (like messaging and SOS) require an active plan. Garmin offers flexible monthly options.

Can I use a satellite communicator internationally?

Yes, especially if you choose a device using the Iridium satellite network, which offers true global coverage.

Do these devices work in bad weather or thick forests?

They work best with a clear view of the sky. Heavy canopy or deep canyons may delay transmission but usually won’t prevent it entirely.

What happens if I accidentally hit the SOS button?

Most devices allow you to cancel a signal within seconds. If it’s sent, you should immediately contact the response center and inform them it was a mistake.

Can I use a satellite communicator as a GPS navigator?

Some models (like the inReach Mini 2) offer breadcrumb trails and navigation features, but they’re not as detailed as full GPS devices.
