In our previous post, we took the time to highlight the key benefits of Inmarsat IsatPhones, both Pro and 2 generations. We also outlined the key differences between the two offerings, with the gist of the difference being that the IsatPhone 2 comes with nearly everything the IsatPhone Pro does, with some key improvements. Not to sell the Pro short by any means, because both generations of the Inmarsat satellite phones are durable, reliable, and provide top-quality coverage across the globe.


The Iridium Network

In today’s post, we will transition from the world of Inmarsat and IsatPhones to another top satellite phone brand — Iridium. Iridium Communications Inc., an American sat phone company, operates the Iridium satellite constellation, which is an impressive system of some 66 active satellites which are utilized for data and voice communication via handheld satellite phones. The Iridium network can be described in no other way than amazing in that its coverage encompasses the entire globe — this includes oceans, airways, and poles.


If you are traveling to a remote location and need to feature- and price-compare a bit, we are going to highlight what Iridium has to offer, beyond their impressive array of satellites that provide global coverage. So while you are deciding whether you should buy or rent or if you need access to broadband internet, consider the suite of features that Iridium satellite phones have to offer. In today’s post, we will break down the features of Iridium Satellite phones, Iridium Push-to-Talk, and other Iridium satellite phone features. Keep reading if you are in need of an Iridium sat phone guide, because this post is for you!


A Sophisticated Global Network

Using an advanced mesh network of the aforementioned satellites, the Low Earth Orbit satellites orbit about 781 km over the earth with numerous points of redundancy. The net effect of these technical facts is that Iridium phones soar above most other satellite phone providers when it comes to functioning in terrain that is particularly mountainous. While other satellite networks struggle to be able to provide consistent connection, the sophisticated satellite constellation that Iridium has implemented gives them a clear edge in the market.


What’s more, there is a marginal degree of call latency that callers experience when it’s compared to the more noticeable lag-time often experienced with Inmarsat or Thuraya phones, for instance. As if those facts weren’t enough to successfully separate Iridium’s network from the pack, Iridium boasts a significant edge regarding its call switching. This process occurs in space rather than on earth with Iridium, which means the call path can remain uninhibited by weather conditions on the earth’s surface.



Iridium NEXT

In a 2017 post of ours titled Third Launch of Iridium NEXT Satellites Successful, we shone the proverbial spotlight on Iridium’s latest successful launch. One of eight planned launches that Iridium has planned, the primary benefit of these new launches is found in their ability to provide better satellite interconnectivity, which translates to fewer dropped calls. Higher data speeds are also a key benefit to this launch.


Iridium Satellite Phones And Equipment

The Iridium 9575 Extreme® is the first Iridium satellite phone for sale at Outfitter Satellite that we’d like to highlight. This Iridium phone is by far the most weather resistant and robust phone that Iridium has yet to make. Of course, it comes with global voice from pole to pole, short messaging, short-burst data (SBD) communication services, and 2.4 kbps circuit-switched data. Other features are listed below:


  • Sophisticated weatherization technology sets this phone up with an IP65 rating against both dust and water intrusion. That is a very high rating, for reference.

  • The Iridium 9575 Extreme® comes with a built-in GPS feature that gives you access to your location at any time, in addition to being able to text that location to others. Iridium didn’t stop there, though, as they included a feature to set your phone to automatically text a “breadcrumb” trail of locations during a journey at interval-based times. Be sure to look into optional web-based tracking services to get everything that Iridium has to offer.

  • As an option in case of an emergency, this Iridium handheld phone has a one-touch S.O.S. button so that you can send your GPS location to a predetermined person or group of persons. The button can also send a call to a predetermined phone number as well.


The 9575 Extreme® comes with a special diamond grip armor, 2400 bps data, and is complete with military grade 810F durability. Clearly, there is a lot to like about this satellite phone for sale at Outfitter Satellite. If you order today, the item will be shipped to you in about four business days.


Iridium 9555

If you are looking for a more economical, yet reliable option, consider the Iridium 9555 satellite phone. There is no fluff about this phone, it simply gets the job done when you need it to. The Iridium 9555 can make 2.4 kbps data and phone calls while also being able to send SMS messages. Weighing just 9.4 oz, the phone offers a 3.1-hour talk time with a more attractive 6.5 hour talk time as an available add-on option.


Other features of the Iridium 9555 are listed below:

Iridium Push-to-Talk

Iridium PTT is a unique service that provides unlimited communications among a Talk Group that is located anywhere on the planet. If your organization has groups of people in remote areas who might be dealing with radio dead zones that inhibit communication and therefore safety, Iridium Push-to-Talk might be a critical lifeline for you.


In the past, Push-to-Talk has been expensive, difficult to adapt and deploy, making it not always a feasible solution to problems like the one mentioned above. Iridium PTT uses their sophisticated satellite network to afford groups instant communication functionality. Even if there is little to no terrestrial infrastructure where you might find yourself, PTT is secure (AES-256 encryption standards), instant, and high-quality. Connection speeds are comparable to land-mobile devices, so you can rest assured of the quality of the call as well.


On top of all that, Iridium has made PTT intuitive, based on the needs of organizations across the globe. Configuration between companies, should the need arise, is seamless, making Iridium PTT uniquely interoperable.
