How are Satellite Phones Typically Used?

Satellite phones are essential for travel in remote areas where traditional cell service is unavailable. They’ve been around for decades, but until the launch of the Iridium network, they were too costly for most consumers. Today, satellite phones more accessible than ever, with more affordably priced options including satellite phone rentals and prepaid SIM card plans. Satellite phones are a valuable back up to cell phones because they don’t transmit over cellular or landlines which may be unavailable or damaged by storms and natural disasters.

Satellite phones just need a clear line of sight to the sky for signal reception. Unlike your cell phone, don’t expect your satellite phone to ring indoors, unless you’re next to a large window with the antenna pointing toward the open sky. Satellite connectivity can be affected by buildings, mountains or heavy tree cover that block the antenna’s line of sight to the satellites in the sky. Pilots often keep a satellite phone or Iridium GO! exec on their cockpit dashboard to maintain a signal.

While placing voice calls to a satellite phone can incur significant international surcharges, texting is less costly. The cell phone subscriber with an international SMS feature can text a satellite phone number for about the same cost as a text to an international number. Inmarsat and Iridium satellite phones support text messaging (SMS) and short emails, making communication quick and easy.

For the best in satellite communication, the Iridium Extreme is the most rugged and feature-rich satellite phone available. It uses the Iridium network for unmatched quality and coverage. This IP65-rated sat phone can even withstand being dropped in water while still enabling calls or sending GPS coordinates via SMS or email.

The Inmarsat IsatPhone offers affordable global satellite connectivity. It supports voice, text and includes a built-in GPS receiver. While signal acquisition can be slow, due to the placement of the satellites, call quality remains quite good.

Satellite Phones and Internet Access

Many satellite phones offer data services with limited bandwidth, but few provide Internet access. With an added accessory, you can perform popular online functions on a standard phone. Some devices, connect directly to smartphones via built-in Wi-Fi. A Wi-Fi-enabled satellite device will offer limited Internet capabilities, such as basic email or compressed photos, but is not suited to browsing webpages.

The Iridium GO! satellite hotspot was the first portable Wi-Fi hot spot to enable subscribers to call, text and email from their iOS or Android devices. It’s also more affordable than a traditional satellite phone. Iridium GO! can connect up to 5 devices, providing off-grid access to satellite data, voice and text messaging.

Ideal for those who don’t need a full sat phone, the Iridium GO! Is a compact solution for mobile, portable satellite internet in remote areas. It’s compatible with prepaid SIM card plans and available through rental, making it a flexible option for casual users, remote workers or emergency preparedness.

For those seeking additional bandwidth, the highly portable Iridium GO! exec upports higher data speeds (88Kbps download, 22Kpbs upload) and additional capabilities. It offers voice calls, messaging and email, along with secure file transfers and VPN access for a seamless experience in remote locations. The Iridium GO! exec also offers advantages over Starlink including portability and the ability to make phone calls without IP-enabled phone services.

Leading Satellite Network Providers for Reliable Communication

When it comes to dependable satellite connectivity, two industry leaders stand out: Iridium and Inmarsat. These global communication network providers offer reliable solutions for voice and data communication, ensuring users stay connected no matter where they are. Whether you need coverage in remote locations, at sea or during emergencies, both networks provide the technology to keep you in touch.

Iridium: Seamless Worldwide Connectivity with No Gaps

The Iridium constellation is a full meshed network of 66 low-earth orbit (LEO) cross linked satellites that cover the entire globe. Iridium is the only network offering 100% global communication satellite coverage. Iridium was found to deliver the best call quality compared to other networks, in an independent study. This is one reason why the Canadian Armed Forces and emergency responders trust Iridium for reliable communication.

Traveller’s Note: Although the coverage of Iridium is global, travellers are advised to contact local consulate or customs office for information on any restrictions which may prohibit use.

Inmarsat: Reliable, Nearly Global Communication

Inmarsat operates a network of high-powered geostationary satellites (GEO), delivering dependable voice and data services across most of the world. With strategically positioned satellites, Inmarsat ensures continuous coverage for land, sea and air communications, making it a trusted choice for governments, businesses and adventurers alike.

While Inmarsat offers near-global coverage, service availability may be subject to local regulations. Travellers should check with local authorities regarding any restrictions on satellite communications.

Satellite Phone FAQs

Why do people need satellite phones?

If you spend time in remote areas without reliable landline or cellular coverage, or want an alternative backup, an emergency satellite phone enables you to stay connected when other systems fail. Because the satellites are in space, they aren’t dependent on land-based infrastructure like cell towers. This makes them less vulnerable to events on Earth that can disrupt traditional landline and cellular networks.

What is the difference between a satellite phone and a satellite communicator?

A satellite phone is designed for real-time voice callings and basic texting. Some emergency sat phones also include a built-in SOS button. In contrast, a satellite communicator like ZOLEO satellite communicator supports text messaging (to/from any SMS or email address) along with location sharing and tracking, and SOS alerting and world-wide non-emergency medical assistance. If voice is not a requirement, satellite communicators are extremely affordable, offer robust functionality and are widely used by consumers and businesses alike. If voice calling is a priority, choose a sat phone.

What is a satellite phone and how does it work?

Satellite phones connect to satellites orbiting the Earth. When you make a call, your phone sends a signal to a satellite overhead. The satellite relays the signal to a ground station, which links to the regular phone network. This system lets satellite phones work in remote areas — like oceans, mountains and wilderness — where cell service can’t reach

Can satellite phones send and receive text messages?

Yes, satellite phones can send and receive text messages over the satellite network.

Can an iPhone be used as a satellite phone?

An iPhone cannot function as a full satellite phone, but newer models like the iPhone 14 and 15 offer limited satellite-enabled SOS and texting. This feature is limited to specific situations and regions, unlike a true satellite phone that supports global voice and messaging. For full satellite functionality, you would need a dedicated satellite phone or a satellite communicator like the ZOLEO.

Learn more about how ZOLEO compares to iPhone satellite messaging here.

Do I pay long-distance or roaming charges with satellite phones?

There are no long-distance or roaming charges with the Iridium or Inmarsat communication networks, but oss-network fees may apply. Calling a sat phone from a standard cell phone can still result in higher charges, depending on the provider.

Do satellite phones work everywhere?

Yes, satellite phones work almost everywhere, though coverage depends on the satellite communication network and airtime plan. Satellite phones connect directly to satellites, bypassing local terrestrial networks. This makes them perfect for remote areas with no cellular coverage.

Do satellite phones work on the ocean?

Yes, satellite phones work on the ocean. They connect to satellites overhead — not terrestrial networks. if the satellite network provider offers truly global coverage, a user can access satellite connectivity on the ocean. This makes them crucial for maritime navigation, safety and emergencies.

What is the difference between a satellite phone and a cell phone?

Satellite phones connect to orbiting satellites, not terrestrial networks. The signal travels to a satellite, then to a ground station or another satellite, linking to the public network. This allows satellite phones to work in remote areas, provided there’s a clear line of sight to the sky. Cell phones, on the other hand, rely on nearby cell towers and need coverage to function. Though some newer smartphone models have satellite capabilities, the devices lack the durability and battery life provided by true satellite phones which is often needed for off-grid work and adventures.

Which satellite network has the best coverage?

The Iridium network offers the best global coverage. it provides reliable coverage everywhere — from the North Pole to the South Pole, across oceans, landmasses, and airways. Iridium’s reach and satellite connectivity are unmatched. While Globalstar and Inmarsat also offer good coverage, they have limitations in some remote locations.

How does the SOS emergency feature work on a satellite phone?

Some emergency satellite phones offer SOS alerting which sends distress signals to emergency services or predefined contacts. When activated, it uses satellite communication to transmit your location, even where there is no cell service, helping rescuers pinpoint your exact position. This feature is crucial for getting help in remote areas.

How much is a satellite phone?

The cost of a satellite phone can range from about $800-$2,500, depending on the model and features, such as GPS tracking, emergency SOS and durability.

If I buy multiple satellite phones can they share one SIM card?

No, each satellite phone needs its own SIM card. While you can move a satellite SIM card between compatible phones, each phone must have a SIM card with an active plan or prepaid airtime to make calls.

How quickly can I get a satellite phone?

Roadpost is your trusted satellite phone store, offering devices for sale and rental across Canada. Roadpost offers sat phones for sale and maintains an inventory of most satellite phone models and can generally ship the next business day for orders placed before 3 p.m. ET.

Should I rent or own a satellite phone?

Renting or owning a satellite phone depends on how often you’ll use it. Rent for short-term needs like vacations, business trips or seasonal emergency preparedness or disaster response. It’s flexible, cost-effective and requires no long-term commitment. Satellite phone rental plans often include accessories tailored to your needs. Own a satellite phone if you travel frequently or work in remote areas. It offers long-term value and reliability, though with a higher upfront cost. Think about whether renting or buying fits your needs — especially if you’re looking for a cheap satellite phone rental for emergencies.

Which satellite phone has the best coverage?

We only work with the leading satellite networks. Inmarsat, and Iridium satellite phones all offer different coverage which may be better in certain areas or for certain types of voice, text or data services. The only satellite network that offers complete whole earth coverage (including the North and South Poles) is Iridium.

Who owns the most satellites for phone service?

Iridium owns the largest commercial satellite constellation in the world. They operate a constellation of 66 low-earth orbiting satellites that cover the globe, no matter where on earth you are if you have an unobstructed view of the sky, you can connect over the Iridium satellite network.

Do I pay long distance or roaming charges with satellite phones?

There are no long-distance or roaming charges with the Iridium or Inmarsat satellite communication networks, but cross-network fees may apply. Calling a sat phone from a standard cell phone can still result in higher charges, depending on the provider.

Which satellite phone accessories are worth owning?

That depends on how you plan to use your satellite device. A spare battery is always something we recommend. It comes in handy on extended trips where you may not have access to a power source for recharging, or if you lose the one that comes with your device. Also, all satellite phone manufacturers offer compatible docking stations with an external antenna that can be stationed outdoors, enabling the satellite phone or device to be used inside a cabin, vehicle, boat or plane. These accessories help ensure uninterrupted satellite connectivity and improve phone connectivity in environments where a view of the sky is limited. You’ll find a selection of docking stations and related accessories for each model of phone on our website. You can also live chat or email us at [email protected] if you’d like to discuss options.
