Commonly known as sat – phones, satellite phones are a unique mobile phone model that nearly looks like a cell-phone but so different in functionality. Unlike cell-phones that use towers or terrestrial cell sites, sat phones use orbiting satellites worldwide to transmit and receive signals for effective communication. These phones were invented in the late 1980s to allow communication in areas that standard cell-phones cannot access. For detailed understanding of these phones, walk with us to the latter.

How Do Satellite Phones Work?
After realizing that this is a very commonly asked question, we decided to explain it in detail for better understanding. As stated above, sat phones use satellites that are normally in motion around the earth’s orbit to allow communication throughout the entire planet. That is why with sat phones, it’s easy to make effective calls or send messages on mountains, planes, mid-oceans, or remote places that cellular networks cannot access.
To work effectively, these phones depends on two types of satellite networks. The geostationary and the low earth orbit satellite. The geostationary orbit normally appears above in the sky at a distance of (22,236 mi) above the earth’s surface.
On the other hand, low earth orbit uses lower altitude orbit that is normally from 640 to 1120 km above the earth’s surface. So how do satellite phones work? They work by sending signals to either the geostationary satellite or the LEO satellite that is at the nearest point. In turn, the satellite sends signal to the nearest land-based center (also known as gateway). Then, the gateway sends signal to the recipient’s phone for effective communication.
Is a Satellite Phone Worth It?
Yes. Although some of these phones are pocket-shaking, they are worth buying. This mostly applies to people who travel a lot or work in very remote areas where cellular signals can’t avail at ease. They are also worth because they are vital and essential in natural disaster scenes where cellular terrestrial network has been damaged.
These phones are also easy to use and provide a fast and reliable connection across the globe with no signal hindrance. This also makes it worth an investment.
Who Uses Satellite Phones?
Anyone can use a sat phone as long as it’s connected to a network of satellites. In the early days, these phones were mostly owned by the government, marine companies or rescue organizations for rescue purposes during disasters. Things have changed since private individuals also own satellite phones. Mostly;
- If you are an explorer, traveler, or hiker, you need to use a satellite phone to reach out to friends, family or ask for help in case of an emergency.
- Suppose you work for industries with offices in remote areas such as mining industries, scientific research organizations, or plant industries. Regular cell phones cannot access in such remote areas. Therefore, you need satellite technology to stay connected.
- If you work in NGOs or aid organizations, you need satellite technology to coordinate communication and relief efforts to victims in case of a disaster.

Key Considerations When Buying Satellite Phones
It’s with no doubt that choosing a convenient and reliable satellite phone can be hectic. This requires you to conduct thorough research or ask for advice from people with experience. In this guide, we have provided some helpful factors to consider before buying your satellite phone.
1. Type of constellation
There are two types of constellation in satellite networks; geostationary and low earth orbit constellation. When choosing your satellite phone, consider the right constellation as the two have different areas of coverage. Geostationary satellite covers almost the entire globe as it orbits the earth at a high altitude.
However, it does not cover around the poles. If you live close to the poles or around Hills, Mountains, or trees, avoid geostationary because such factors affect its signal. LEO constellation system orbits at a lower altitude and has multiple satellite systems overhead. Unlike Geo system, if you leave across the poles, LEO has no signal defaults. Its signals are also not destroyed by trees, mountains, or buildings like that of GEO. Therefore, choose the right constellation depending on your location.
2. Satellite Network carriers
Four satellite network carriers are well known for their effectiveness. There is; Inmarsat, Iridium, Thuraya, and Globalstar. When buying your satellite phone, you should keenly choose the right carrier. Avoid Inmarsat carrier if you live around the North or South Pole because their satellites are normally placed over the equator. This makes its signals so weak at the poles.
Iridium carrier is convenient to consider as its network operates under multiple satellites in a polar orbit. This makes it possible to relay its network coverage across the entire globe. It does not restrict any location.
Thuraya does not provide coverage everywhere. Consider this carrier if you live only in Asia, Europe, Africa, Australia, and the Middle East.
Avoid Globalstar if you are in North America.
Satellite phones are expensive to acquire. For that reason, ensure your phone’s durability is not at stake before purchase. Ensure your phone has high weather, water, and breakage resistance ability to avoid frustration when in harsh outdoor environments.
3. Purchase and maintenance price
Price is a very vital factor to weigh before buying your satellite phone. However, you should have in mind that high cost is relative to quality. It’s said that Iridium phones are the toughest, most quality, but most expensive. You should thus set your budget high and get a reliable and quality satellite phone.
You should also consider airtime plans before getting your phone. Some carriers have high-cost plans than others. However, most carriers offer call plans ranging from 1.15 to 3.50 $ per minute.
4. Pre-paid deals
It is important to consider carriers with prepaid deals while buying your phone because they are cost-effective. These plans are exquisite to users that travel a lot hence not aware how often or little they might use their satellite phone. In case they use their phone a bunch and more than expected, then there will be no additional cost.
It’s important to consider additional features like internet or email access while buying your satellite. Also check out your phone’s texting limit, Bluetooth capability, and safety measures like ‘one-button SOS ability’ to call for help during an emergency. Other factors like; battery life and country/ region restrictions are also important to consider.

Can you call a satellite phone from a cell phone?
Yes. It’s so easy to make a call from a cell phone to a satellite number. All you need to know is the recipient’s exit code. In USS, the exit code is 011, Mexico 00, Australia 0011 among others. After, dial your recipient’s satellite carrier number and connect to your satellite call.
Does AT&T offer satellite phones?
Yes. In 2010, AT&T introduced its first satellite compatible phone known as TerreStar Genus. The phone uses satellite network for data and voice communications, has internal antennas, unlike other satellite phones whose antenna is outside. The handset goes for 799$.
As much as satellite phones are costly to buy and use, these phones are important to own. They act as a safety measure in case of a disaster. They are also important because they are not limited to any coverage area. If you are a frequent traveler to remote or isolated areas, pick the best satellite phone from our list above.
