Iridium Extreme Satellite Phone Rental

Our Iridium Extreme satellite phone rentals with their omni-directional antennas are particularly suited for use out at sea, mandatory for those traveling at or near the polar regions, and also best for mountainous terrain.

We supply our Iridium Extreme satellite phone rentals in tiny cases measuring only 20x5x5cm with a total weight of only 900g, a good 50% lighter and smaller than what you will find elsewhere from our competitors.

Also included is our own highly practical charging solution being USB charging cable that you can plug into any USB port with USB car and wall plug adaptors. Optionally you can also add a solar charger if required.

Our Iridium Extreme satellite phone rentals are fairly robust, however their antennas are prone to damage when thrown in a backpack therefore should always be kept in the protective cases we provide them to you.

Simply select the duration for which you require your Iridium Extreme satphone rental and add to cart together with a bundle of airtime, which will be your allowance to use over the duration of your rental period.

You will specify the start date for your Iridium Extreme satellite phone rental during the checkout process on our website, and we will make sure your rental phone reaches you a day or two before your start date.

You need to make your own arrangements to have your rental phone delivered back to us at the end of the rental period, and there are surcharges for phones that we receive back later than the paid-for timeframe.

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

Iridium Extreme Rental Terms

You will select your Iridium Extreme rental start date i.e. the date by which you want to receive your rental during the checkout process on our website, and your rental duration runs from the date you select as the start/delivery date on your order, until the day we receive the phone back.

We will deliver your Iridium Extreme satellite phone rental to you just before the start of the rental period, which will give you an opportunity to get to know and make some test calls with your phone.

You are then required to make arrangements to have the phone returned to us after your travels, via either courier or Royal Mail tracked service back to our distribution centre in Purley on Thames. Rentals received back returned later than the booked time-frame will be charged at £7.50 per day.

Should you use 80% or more of your pre-purchased airtime allowance during your trip, we will automatically recharge your account with another 75 minutes of airtime at a cost of £100.

Please refer to our website terms and conditions for the full terms and conditions of our rental services.

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.

    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.

      Gill thanks for the kind words and hope Barra was a good experience, was a pleasure dealing with you.

    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.

    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.

      Hi Patrick,

      I am glad the Iridium Extreme wasn’t required for any emergencies and you enjoyed your trek, pleasure dealing with you.
