How Satellite Texting Actually Works—And Where It Fails

I love hiking, but for years, I've ignored the advice to carry a satellite device. When my phone doesn't have service, a satellite device can help me communicate with emergency personnel. But I kept forgetting to buy one before my next outdoor adventure.

My lazy side was relieved when I realized I was carrying a solution in my pocket all along. My Pixel phone has a Satellite SOS feature, which can help me connect to a satellite in order to contact emergency services if I’m outside cellular coverage.

When cell service or Wi-Fi isn't available, satellite texting is a great plan B for communicating. It works completely off-grid. But there are some limitations to it.

Let's dive into how satellite texting features work and what to know before using it.

Many phones, like Pixel and iPhones, are equipped with satellite texting. When your phone can't reach a cell tower, it will connect to a satellite instead.

Here's a general look at how satellite texting works:

• Your phone detects no cell service.
• Your phone starts looking for a nearby satellite. You may get a prompt to point your phone in a certain direction for the best chance to connect.
• Your phone sends a radio signal to the satellite.
• The satellite sends the message to emergency services or your designated contact.

Once you send a message, stay where you are. This helps ensure you stay connected, and an emergency dispatcher can text you back. However, as satellites move, you may get prompted again to point your phone in a different direction.

Connecting to a satellite isn't as easy as connecting to a cell tower. A few extra steps are necessary to make sure your message gets sent and that you can receive messages from emergency dispatchers. Here are a few tips:

• Make sure you have a compatible model with satellite texting features and your phone’s default messages app is enabled.
• Check availability in your area. Pixel Satellite SOS can work in North America and Europe, while iOS works in the U.S. and parts of Canada.
• Check the fine print. For example, Pixel devices only cover up to two years of Satellite SOS.
• Choose a designated emergency contact and add their phone number.
• Find an open area with minimal obstructions for the best shot at a stable satellite connection.
• Keep messages short for faster send times.
• Monitor your battery closely, since satellite connections use a lot of power.

Satellite texting is already connected to the local emergency number. If you also want to add an emergency contact, you'll need to enter their number. The designated person will receive a text message, and your location will be shared with them. They don't need a satellite device to get your emergency message.

When you attempt to send an emergency message, your device may ask some questions. This is to help determine what kind of help you need.

Emergency services will receive information like your name, location, device information (like battery level), and your emergency contact.

Satellite texting works best when you're outside of regular cell coverage. Places like hiking trails, camping spots, or rural roads are most likely to benefit from having access to satellite texting. Satellite texting can also come in handy if there's a natural disaster or cell tower outage.

In emergency situations, being able to send one important message can make a big difference. From sharing your location after a car breakdown to receiving medical assistance, satellite texting can make it easier to get help.

Satellite texting depends on a clear path from your phone to a satellite overhead. That makes it much less predictable than sending a text through a nearby cell tower.

Here are some hurdles that make sending a message via satellite a time-consuming venture:

• Satellite is moving: Your phone may need time to find a usable satellite, and you might need to reconnect later when the satellite moves.
• Signal is weak: Your small phone antenna has to send a signal hundreds of miles away.
• Obstructions can block signals: Dense forests, canyon walls, or stormy weather can interfere with the signal.
• Connection is low-bandwidth: Keep messages short since it's sent in a reduced, low-bandwidth format.
• Timing varies: A message might go through quickly, take several minutes, or even fail if conditions are extremely poor.
