Satellite phone
Written by Bradley Page

Imagine you are out in the mountains or in the jungle and there is an emergency- perhaps a tornado or a flood, but your phone fails to pick the network. What would you do? To avoid these kinds of situations you should consider buying a satellite phone. A best buy satellite phone works as a reliable back up when your cell phone fails you.

While the thought of acquiring a satellite phone may never have crossed your mind, learning about its facts and the low cost of acquiring the gadget will have you thinking twice. A satellite phone can work virtually anywhere on earth and is hardly affected by strong and violent storms. Not to worry about their weight as generally satellite phones weigh a few ounces and are of the same size as your ordinary cell phone.

For a satellite phone to operate, it requires a line of site with the sky to get a signal for service. Voice calls made to a satellite phone will cost a significant international calling surcharge while sending a text is treated as an ordinary SMS. Satellite phones can be hired or bought, depending on the period of usage.

How a Satellite Phone Works

Unlike cell phones, sat phones neither send nor receive signals from cell phone towers. Rather they communicate via a web network of satellites in Low Earth Orbit (LEO). The network of satellites may also be fixed in a geostationary orbit that is above the equator. The reason as to why the satellite network is never affected by harsh weather conditions is because the satellite network is located about 500- 1000 miles above the surface of the earth.

What You Should Know About Satellite Phones

  • Unlike ordinary cell phones, satellite phones do not have internal antennas. Their external antennas have to be pulled out for them to work properly in sending and receiving calls. If their antennas are not extended the phone will not work because of the way radio waves are propagated.
  • Calls made to satellite phones are usually very costly when coming from the public networks. It will cost you up to $10 a minute with regards to the tariff plan and the carrier. In case you intend to get calls on your sat phone, it would be best if you choose a carrier that offers over dial capabilities or Direct Inward Dial.
  • The quality of voice may be lower than is the case with cell phones as the bandwidth is limited to minimize power requirements. Latency or delay may be experienced between when you talk and when the party on the other end responds. This often occurs when communicating via a system with satellites located in geostationary orbit.
  • Whereas some satellite phone carriers offer global coverage, this is never 100% certain. There could be some dead spots depending on your location. This normally happens as a result of your surrounding such high buildings, mountain ranges, trees or any other obstructions. This is also dependant on the design of the satellite constellation.
  • Although earlier on we had mentioned that sat phones have almost the same size like that of an ordinary cell phone, there are differences in design such as in terms of soft buttons, options, antennas and displays.

Features to Keep an Eye On When Shopping For a Sat Phone

Simplicity in Usage

If you are a first timer with a satellite phone, then ease of use should be your top most priority. Simplicity and ease of use also plays in because satellite phones are used especially in areas with poor or not cell phone network. I’m certain you do not want to struggle sending a text message or making a call during an emergency.

Reliable Network Coverage

The network of satellites of a sat phone should be in a geostationary orbit. One with a network of satellites that is in motion is at times less reliable especially when the satellite you are using shifts out of range. You should ask yourself in which location you will be using your gadget then choose a network that provides you with flexible as well as reliable coverage.

Emergency Help Button

This is an important feature especially for backpackers going to the wilderness with their phone. Satellite phones usually come equipped with onboard GPS to locate you. So all you need to do is press a button and your location will be transmitted right away to emergency workers.

Regardless of where you are on earth and no matter where the emergency workers are, they will be in a position to locate and rescue you.


This is a standard feature you will not miss in most sat phones. However, you need to know that voicemail features vary from handset to handset. Get to find out how long your message can be, does it allow you to easily navigate through your messages to skip, save, delete or replay as you would want to?

Text and email messaging

Just like your cell phone, a satellite phone cannot only make voice calls but also send and receive text and email messages. While shopping, confirm how much you will be charged to send a text or an email.

Hands- Free operation

I am sure you have once been in a situation where you want to talk on your phone but not use your hands. As you go about shopping for a satellite phone be on the lookout for a hands free feature. This is a lifesaver feature especially when you are out in the wild.

Weather resistance

This is one of the most important features in determining a quality sat phone. This is more so with the environment in which you are going to use the gadget. You definitely do not want your phone damaged in a harsh storm. If anything that is when you need it most.

While out mountain climbing, backpacking or out in a remote place, your phone is likely to get exposed to dust, extreme temperatures, rain and snow. If your satellite phone is not all weatherproof, it is certainly not going to offer reliable network connection.


This is a crucial point to ponder. There are different satellite phones in the market with different distinct features and capabilities. Prices will vary depending on the features and accessories that a phone comes with. Apart from knowing what your desired gadget can do, be sure that the price matches the features it comes with. You do not want to purchase an item later on to find out it was a waste of your hard earned money.

Airtime option

You can select the prepaid or postpaid option, depending on how long you are going to be with the phone. SIM cards are normally preloaded with airtime units that are to be activated by the manufacturer or the vendor.

It takes about 90 days from the time of activation for the data to expire.

Other capabilities
