Who is the product for?

You might wonder, this device looks just like a cell phone; why do I need it when I’ve already got one? Well, as a satellite phone, the Iridium 9575 is very different from the smartphone or whichever cell phone you’re holding.

This product is for you if you are going backpacking in areas where there is no cell tower coverage. This implies areas where you cannot use your regular mobile networks like AT&T, Verizon, etc.

These are majorly remote locations. Examples include high mountains, deserts, deep woods, and water. While camping in such locations, anything can happen. Though not wished, you might run into a few challenges where you’ll need help from those on the outside.

If you’re backpacking in an area where your mobile carrier doesn’t cover, how do you communicate with others if there’s an emergency?

This is one reason why you’ll need the Iridium 9575 Extreme satellite phone – for your safety. It was equipped with advanced features to deal with emergencies.

The satellite phone connects with the Iridium satellite constellation that was launched far back in 1998. With the Iridium 9575 Extreme satellite phone, communication is very easy, and its global coverage means you can use it anywhere, even if not in the United States.

Key features and benefits

Prepaid & Postpaid SIM Cards

The Iridium 9575 Extreme satellite phone supports both prepaid and postpaid SIM Cards, giving you the flexibility to choose how you want to pay your bills.

With a prepaid SIM, you pay upfront – before you make use of the service. On the other hand, with a postpaid SIM, you pay after you’ve used the service.


This satellite phone comes with a built-in GPS. You’ll find this feature extremely useful, and it’s one of the key reasons people are buying it.

With this Global Position System, you can identify where you are at all times, and it’ll also help you navigate to other locations.

Emergency SOS

Just as in your iPhones and Androids, emergency SOS allows you to call emergency contacts quickly and easily. This is a life-saving feature should you run into problems.

You can quickly call 911 should there be any fire or medical-related emergencies. Note that the Iridium 9575 Extreme satellite phone is the first satellite phone to have this feature.

Two-way SMS

The two-way SMS feature means that you can send automatic replies via SMS to anyone from your backpacking camp.

You can set up a shortcode that others can use to reach you and set replies for specific messages. This is an ideal way of letting others know whatever you’re up to.

Short Email Capability

The Iridium 9575 Extreme satellite phone communication features are not limited to calls and SMS alone; you can also send short emails and receive them.

So, if you’ve got a very important email to send, perhaps about work, school, you won’t need to leave your camp.


With notifications, you won’t miss any important messages. The satellite phones show notifications of received messages, missed calls, emails, and more.

If you’re on a prepaid plan, you’ll also get notified when you’re running low on airtime so you can refill. The same applies to instances when your SIM card is to expire.

IP65 rating

The Iridium 9575 Extreme satellite phone is an IP65 rated device. IP65 rated products are top of the list in terms of durability.

An IP65 rating implies that this satellite phone is dust-tight and protected against water; in other words, dustproof and waterproof. Also, it makes the satellite phone shock resistant.

Illuminated weather-resistant keypad

As an IP65 rated product, it’s expected that the devices’ keypad is weather resistant. However, the pointer feature here is the illumination.

The keypad is illuminated to use the satellite phone conveniently at night or in any low light condition. This feature could also suit your artistic taste.
