Business buyers know the importance of choosing the best satellite phones and equipment to address their organizational user’s voice and data connectivity requirements. While leading satellite manufacturers like Iridium, Inmarsat, and Globalstar all offer a range of voice and data connectivity devices, there are important differences that enterprise buyers should consider. These may include the:
It is important to remember that regardless of the specific features of any satellite phone, if it doesn’t offer reliable coverage in the region it will be used in, it won’t be useful.
A satellite phone is a type of mobile phone. Like a cell phone, a satellite phone (also called a sat phone) is compact, lightweight and can be used for voice communication, text messaging and low-bandwidth Internet access (data). Some models of satellite phones also support Bluetooth and Wi-Fi, which allows the satellite phone to be used with a headset or connected to a laptop. However, there are some important differences between satellite phones and cell phones:
In summary satellite phones and cell phones offer similar voice and data communications services, in different ways.
The comparison chart below is designed to help you select the satellite phone best suited for your needs including quality of service (QoS), potential limitations, and advantages one satellite phone may have over another.

The answer to this question depends on your needs. In addition to specific features and functionality that you may need, if you want a phone that will work anywhere in the world, an Iridium phone like Iridium 9555, Iridium Extreme or Iridium hotspot like Iridium GO!, or Iridium dual-mode device like Iridium Extreme PTT is best. If you’re not concerned about coverage in the polar regions, Inmarsat offers an excellent alternative, its IsatPhone 2 is that is also less expensive.
The cost of a satellite phone service depends on the type of service and the features. There are no long distance or roaming charges with the Iridium or Inmarsat satellite networks.
Monthly satellite phone service guarantees 'always-on' access to airtime until the service is cancelled. It is a highly convenient option that is preferred by most business and government.
Monthly Satellite Phone PlansPrepaid satellite phone airtime is often more affordable but airtime expires. It can be can be a good option for short term seasonal use, or budget-conscious buyers.
Prepaid Satellite PhonesSat phone rentals include equipment and airtime and are a great option for short-term projects, travel, or unanticipated requirements like emergency prep or disaster response.
Satellite Phone RentalsWhen satellite phones first came into use in the 1990s, they were quite expensive and therefore they were primarily used by government and organizations with remote operations, including: public safety, scientific research, oil and gas, mining, forestry, utilities, engineering, construction, transport, shipping and more. In 2007, lower-cost satellite messaging devices and personal trackers emerged, and consumer use of sat phones and text messaging devices grew as both devices and airtime became more affordable.
Today satellite phones and satellite messaging devices are used by outdoor enthusiasts and by businesses in a range of applications including: emergency preparedness and business continuity, remote mobile office, executive travel, and work alone check-in and safety monitoring.
Satellite phones and cell phones both offer users voice and data connectivity. Like your cell phone, where a satellite phone will work, depends on the coverage offered by the satellite network and the airtime option you’ve selected.
Satellite phones can be a valuable back up to traditional phones because they operate independently of terrestrial communication or cell phone networks, which can be unreliable or non-existent in less populated regions and can be vulnerable to natural or man-made disasters.
Cell phones and smartphones operate over cellular networks and communicate via land-based (terrestrial) cell towers. Satellite phones operate over satellite networks, communicating via satellites that are either orbiting in a fixed location above the Equator (Inmarsat is an example of this geo-stationary (GEO) type of network), or in a low earth orbit (LEO) like the Iridium and Globalstar networks. The advantage of LEO networks is that the satellites orbit closer to space, meaning there is less latency than with a GEO network.
Like other personal communication devices, satellite phones can be used for any voice, text messaging or data application. For consumers this includes personal safety and connectivity in the back-country or around the globe where cell coverage may be unavailable or unreliable.
Satellite phones can also be used to make and receive satellite calls inside a building, vehicle, plane or boat provided they are used with specialized accessories like a compatible docking station or external antenna.
Use satellite phones in-building (including PBX integration), remote camp, or trailer.

Use satellite phones in a car, truck, mobile command center or emergency vehicle.
View ProductsGenerally, satellite phones are designed to work outdoors, out-of-the box. Accessories can extend their utility to use indoors. To transmit, the satellite phone’s antenna must have an unobstructed direct line-of-sight with the satellites orbiting above Earth, which means the phone/antenna must be outdoors. However, most satellite phones can be used with specialized equipment like an external antenna, which enables use of a satellite phones in a building, vessel or vehicle. A cell phone can be used indoors provided it is in range of coverage, although some materials like thick concrete, steel and iron can obstruct cell signals in some indoor environments.
Satellite phones can be purchased from online stores like Roadpost or specialized dealers and retailers.
