Satellite Phones

Because satellite phones operate using signals from satellites orbiting the earth, they do not have to rely on ground-based cell towers like our everyday smartphones do. So, as long as your satellite phone has a clear line of sight to the sky, you will be able to pick up a signal and make communication with someone from even the most remote regions.

Satellite phones serve to bridge the communications gap where traditional comms infrastructure does not exist or has become damaged or destroyed. They are ruggedized enough to be taken into hazardous environments, even warzones, where they are used to coordinate rescue missions or communicate with crew on the ground.

Compact, lightweight, and highly reliable, satellite phones are among the first things people consider when venturing into isolated regions, especially if they go alone, to address their own peace of mind that they can make contact with friends, family, or emergency services should they run into an unexpected situation.

Satellite Phone Frequently Asked Questions

What are satellite phones?
Satellite phones are mobile communication devices that connect directly to satellites instead of relying on terrestrial cell towers, providing coverage in remote areas where traditional cellular networks are unavailable.

How do satellite phones work?
Satellite phones communicate with orbiting satellites to transmit voice, text, and data. Depending on the network (e.g., Iridium, Inmarsat, or Thuraya), they offer global or regional coverage.

Who should use a satellite phone?
Satellite phones are ideal for travelers, adventurers, emergency responders, remote workers, and anyone operating in areas without reliable cellular coverage, such as mountains, oceans, deserts, or disaster zones.

Do satellite phones work everywhere?
Most satellite phones provide global coverage, but this depends on the satellite network. For example:

Iridium offers true global coverage, including polar regions.

Inmarsat covers most of the world, excluding polar areas.

Thuraya has regional coverage, primarily in Europe, Africa, Asia, and the Middle East.

Do satellite phones require a subscription or prepaid plan?
Yes, satellite phones require a service plan, either as a monthly subscription or a prepaid option. These plans cover airtime usage and may include voice, text, and data services.

What features should I look for in a satellite phone?
Key features include global coverage, GPS functionality, text messaging, emergency SOS capabilities, durability, battery life, and compatibility with accessories like external antennas.

Can satellite phones be used during emergencies?
Yes, satellite phones are vital during emergencies, as they work in areas without cellular coverage. Many models include an SOS button or are compatible with emergency services like GEOS.

Are satellite phones durable and weather-resistant?
Most satellite phones are built for rugged environments and are water-resistant, dustproof, and shockproof. Specific durability ratings depend on the model, so check the product specifications.

How long does the battery last on a satellite phone?
Battery life varies by model but typically lasts 8–30 hours of talk time or several days on standby. Portable battery chargers or solar panels can extend usage in the field.
