While the cell phones use terrestrial lines to communicate, the satellite phone uses a satellite network. From secret services to weekend trekkers/hikers, the satellite phones act as an effective communication device. Compared to traditional cell phones, satellite phones are fringe and niche. They are familiar with their extensive coverage among people who spend a substantial time at remote locations, maritime people, and emergency services. Whatever the requirement, best satellite phone offers the means for reliable and secure communication.
Types of Satellites Phones
The satellite phone service providers use Low Earth Orbiting and Geo-stationary satellites to communicate.
Low Earth Orbit Satellites: Satellites that orbit closer to the earth at an altitude range of 500 – 2000 Km. Owing to the low altitude, the energy requirement and communication delay are minimal. It can offer high bandwidths.
Geostationary orbit satellites: A geostationary satellite or a geosynchronous equatorial orbit satellite orbits the earth at an altitude of 35,800 kilometres above the equator. It follows the direction of the earth’s rotation. The distance from the earth can cause latency in communication.
Satellite Constellations: The satellite phone’s network service providers rely on multiple satellites orbiting the earth. Be it, Low earth orbit satellites or Geostationary orbit satellites, there would be multiple satellites working in a system, as a part of a satellite constellation.Unlike a single satellite, the constellations can offer reliable, global network coverage. At any given point of time, the constellation ensures availability of a satellite. Satellites orbit in complementary angles and connect to ground stations distributed across the globe. Inter-satellite communication ensures efficacy.
Satellite Phones – Are they different?
Connectivity: Relying on satellites for communication, they avoid the installations of infrastructure required in the area of coverage. It makes satellite phones reliable in remote locations and isolated areas, which are unlikely to have a cell phone tower. The phones require a line of sight to communicate with the satellites, and it is unlikely to have quality communication inside enclosed structures. But they offer connectivity despite the absence of infrastructure, the main purpose of its design.
Reliability: Since the satellite phones communicate with satellites above the earth, it doesn’t rely on terrestrial connections to communicate. It makes them reliable during times of emergency if the infrastructure supporting the communication has failed.

Best Satellite Phones 2020 Buyer’s Guide
Ease of use: The satellite phones don’t look like the typical smart cellphones. While there are satellite phones which work without extending the antennas, the majority require extended antennas. Clearer the line of sight to the satellite, better the quality of the call. The communicating device of service providers using geostationary satellites is similar in the size of a notebook. The size shouldn’t become a hindrance. The differences in terms of display, buttons and user interface will vary w.r.t cost of phones and service provider.
Network Coverage: Since the satellite phones use different satellites for communication, their network coverage might vary. The service providers using Geostationary satellites may have limited coverage as you move further from the equator. The service provider using LEO satellite constellation can provide network coverage near the poles. It is prudent to match the network coverage of the provider with your geographical requirement before choosing them.
Email/Text: Most of the satellite phones can send and receive text messages, but they come with size limitations. While the phones can handle low data requirement of emails, extensive internet access depends on the service provider and compatibility of the handset.
SOS: Safety is paramount for people working in remote locations. The satellite phone carries an SOS function that tracks your location using GPS.
Weather Resistance: Encountering harsh climatic conditions is prevalent while traversing multiple terrains. While the satellite phones come with a basic level of water-resistance, the degrees may vary. Ensuring it first-hand will reduce the hassles one may encounter in the future.
Service plan: The satellite phones, unlike the smartphones, are costly to possess and costlier to use. The cost of intra-network calls and inter-network calls vary to a great extent. Incoming calls from the cellphones and landlines can cause a dent in your wallet. Understanding the requirement and choosing the service plan can reduce the cost of airtime. Renting satellite phones, in case of a sporadic user, can reduce your cost to significant levels.
Dual-mode satellite phones: The dual-mode satellite phones are devices capable of using the cell phone network and satellites for communication. The phones will route your communication through cellphone towers by default. In case of absence of cellphone network coverage, the phone will switch to the satellite mode. While they may come at a premium price, it is a feasible solution for personnel with extensive travel requirements.
Choosing your Best Satellite Phone in 2020
Depending on your geographical requirements, the choice of satellite phone can vary. Unless you aren’t venturing close to the North or South pole, Inmarsat ISatphone 2 is the best satellite phone. It comes with the optimal balance of features, cost of the handheld device and an array of prepaid/postpaid options. If curiosity takes you to the arctic or the Antarctic pole, Iridium Extreme 9575 is indisputably the best option. The network coverage of Iridium is second to none. If you require the features of both satellite and smartphones Thuraya X5 touch offers both at a premium with limited coverage. If you are looking for a satellite phone with basic functionality, Iridium 9555 is the right fit. The Global star, with its limited coverage and affordable price tag, works inside America but has a patchy network coverage otherwise.
