Iridium Extreme PTT Satellite Radio Rental

A team spread across an ocean, a border, or a route that runs toward the poles is still a team that needs to hear each other. The Iridium Extreme PTT puts every handset on one talkgroup channel with pole-to-pole coverage, so nobody drops off the channel because of where they are standing.

The date you choose is the day it arrives. Pick the day you want the equipment in your hands, not the day you leave. Your rental starts the day you receive it and ends the day we get it back, so leave yourself a day or two to test everything before you travel.

What you can rent

Every unit is pre-tested and activated before it leaves the warehouse, so it works the moment you switch it on. Most orders ship the same day, and you can collect in San Diego if that beats waiting on a courier.

What it's good for

Iridium's network covers pole to pole, so a talkgroup built on it holds together across an ocean crossing, a border crossing, or a route that runs into high latitudes where other networks thin out or stop. If the job spreads your team across a wide, remote area and everyone still needs to be on the same channel, this is the radio built for that.

It is also worth knowing that Iridium push-to-talk was a military-only capability for years and has since been cleared for civilian use. The same channel technology built for that kind of coverage requirement is now available to rent.

Who it's not for

If your team is staying on one site within range of an existing repeater, ordinary land mobile radio will do the job for less trouble and without a talkgroup plan. And if what you actually need is to reach one specific person rather than a group, rent a satellite phone instead. The Iridium Extreme PTT earns its keep specifically when the team is spread out and off the grid.

How the talkgroup plan works

This rental runs on a monthly talkgroup access plan rather than a bundle of minutes. Every handset assigned to the talkgroup shares the same channel for the length of the rental.

One thing it cannot do: take a US phone number. A talkgroup has no number to dial, so if part of the job also needs someone reachable by an ordinary call, add an Iridium handset or the Inmarsat IsatPhone 2 to the order alongside the PTT radios.

What arrives

Every unit is pre-tested, activated and verified before it leaves the warehouse, so it is ready to join the talkgroup as soon as it's powered on. Accessories are available to add by the day if the job needs them, including a jump starter battery pack, a magnetic mount, a data kit or a Pelican hard case for transport.

Renting first, buying later

If this deployment is the trial run before your team owns its own radios, the push-to-talk rental hub covers both PTT radios side by side, and the Iridium Extreme PTT is also available to buy outright once you know it's the right fit.

Questions people ask before they book

Does the Iridium Extreme PTT work outside the US?

Yes. It runs on Iridium's network, which covers pole to pole, so the talkgroup holds together well outside US borders, including at sea and at high latitudes where some other networks thin out or stop working altogether, which is exactly the gap this radio is rented to close.

Can I add a US number to this rental?

No. A talkgroup has no number to dial, so a US number cannot be added to a PTT rental of any kind. If you also need to be reachable by an ordinary phone call, rent an Iridium handset or an Inmarsat IsatPhone 2 alongside it.

Is Iridium PTT legal to use as a civilian?

Yes. Iridium push-to-talk was a military-only capability for years and has since been cleared for civilian use, which is why it's available to rent here. The talkgroup itself runs on the same pole-to-pole Iridium network used for other Iridium rentals, just switched to a shared channel instead of one-to-one calls.

Does the talkgroup still work if my team crosses a border or an ocean?

Yes, that is what this radio is built for. Iridium's coverage runs pole to pole, so the same talkgroup holds together across a border crossing or an open-water route rather than dropping out at the edge of a country or a coastline.

What accessories can I add to the rental?

A jump starter battery pack, a magnetic mount, a data kit and a Pelican hard case are all available to add by the day, alongside the handsets themselves. Add whichever ones match how the radios will actually be carried and charged on the job, rather than the full list by default.
