Iridium Extreme Satellite Phone Rental

Our Iridium Extreme satellite phone rentals with their omni-directional antennas are particularly suited for use out at sea. They are also mandatory for those traveling at or near the polar regions as Iridium is the only satellite network providing coverage at the polar regions. We supply our Iridium Extreme satellite phone rentals with mains charger and car charger in a small but very tough Pelican case.

We offer our Iridium Extreme satellite phone rentals with your choice of airtime allowance to use over the duration of your rental period. Should you deplete your pre-purchased airtime allowance during your trip, we will automatically recharge your account with another of the smallest airtime bundle available for your phone being 35 minutes of airtime at a cost of £70.

Your rental period commences on the start date you select when making your Iridium Extreme rental booking on our website, however we will usually ensure that your rental phone reaches you a couple of days before the start of your rental period. We will send your Iridium Extreme satellite rental phone to you at the start of the rental period, and you need to arrange to return it back to us at the end of the rental period. Rentals returned later than the booked time-frame will be charged at £7.50 per day.

Our Iridium Extreme satellite phone rentals are supplied with a highly practical charging solution, being a simple USB charging cable which you can plug into any USB port, or even a solar panel. We also include a car and UK wall plug adaptor for added convenience.

To ensure availability, place the order for your Iridium Extreme satellite phone rental at least 14 days before your rental start date.

Iridium 9575 Extreme Coverage Map

Iridium Satellite Phone Network Coverage

Iridium is the only satellite network offering truly global coverage including all landmasses, oceans and airways.

Note that the functionality of Iridium handheld satellite phones may be limited by certain regional vouchers, such as the African voucher which can only be used to make calls from Africa.

SOS Button

If you have rented your Iridium Extreme and you want to be able to make use of the SOS button on your phone, you will need to contact GEOS and buy travel insurance and or search and rescue insurance prior to your travels. You will be required to register your rental phone with GEOS prior to departure, and you will also need to deregister it from GEOS after your return. There is a USD50 handling fee for us to handle deregistration on your behalf.

Simply register your phone at and you can travel with the peace of mind of knowing that when you press that SOS button, the guys at GEOS will know you’re in trouble. During registration you will inform GEOS of who your emergency contacts are, so that when you press the SOS button they know which relatives, friends, or colleagues to notify that you’re in trouble.

If you intend to be able to make use of the SOS button in an emergency it is imperative that you test it before your departure from civilisation to make sure that it functions correctly and that you are satisfied that it is working OK. Please note that, the standard service from GEOS does not include any search and rescue (SAR) services. Should you want search and rescue you can sign up for that as an optional extra, at a nominal fee. See the GEOS website for details.

  1. Artic Trail trek in Greenland

    Patrick (verified owner)

    Last year I used Ashbury Satcom to rent an Iridium Extreme Satellite Phone for the Artic Trail trek in Greenland. With no alternative method of communication for 8 days a reliable and cost effective sat phone was essential. The service we received from Charles was impeccable – helpful and informative he ensured that we signed up for the correct package and made sure that the phone arrived exactly when promised. Fortunately we didn’t need to use the phone for emergency purposes but it was a reassuring part of our kit and was handy for the occasional phone call home. Interestingly the reception was so good I’m pretty sure my wife thought we hadn’t actually left the country!
    If you need a sat phone then Ashbury Satcom come highly recommended – we will be using them again for our next trek to the Caucasus Mountains.

  2. Iridium 9575 Extreme Sat Phone - Rental

    Luiz (verified owner)

    I recently required a sat phone for a sailing trip from Falmouth to La Coruna via the offshore non stop route and contacted Ashbury Sat Com. I was slightly anxious about the phone being delivered on time as I had no leeway for delays but I needn’t have been as the phone arrived exactly on the date specified. Well packaged and very simple to work, just like one of the old type mobile phones really. I did not use it in conjunction with a laptop, just simple phone functionality but the instructions were clear should you want to send and receive text messages. Charles was very helpful and I don’t hesitate recommending Ashbury Satcom.

  3. Excellent, helpful service at very short notice

    Gill (verified owner)

    I know absolutely nothing about satellite phones but needed one at very short notice for a trip to Barra in the Scottish Outer Hebrides. Charles was extremely helpful in advising me what phone would work best there, and got one to me overnight. The instructions he sent were also very helpful. It was excellent service and I’d not hesitate to recommend Charles and Ashbury Satcom.
