Things to Remember About Satellite Phones

When it comes to purchasing a satellite phone, it is important to remember that they operate differently to everyday smartphones, and may not work in any one location. Some satellite phones have global coverage, however, it is important to check the network's coverage beforehand so you know which regions get the best reception. The more advanced models come with integrated tracking functions and SOS abilities for emergencies, so you will need to decide whether aspects like this are necessary for your trip before departure. Finally, if you want to make more than just voice calls while you are away, you should choose a satellite phone that comes with the ability to send basic data packages such as emails, which some of our handsets do.

Satellite Phone FAQs

Satellite phones bridge the voice and data communication gap between remotely-operating teams and individuals and key contacts back home. They operate beyond the reach of traditional mobile signal, meaning they can be used in even the most remote or hostile regions from warzones to coordinating rescue missions at the scenes of natural disasters.
We strongly recommend you asses your individual situation before deciding whether to buy or rent a satellite phone. If you only need the device for a matter of days or weeks, we highly advise renting as it will be much cheaper for you. However, if you plan on using a sat phone for an extended period of time, and not just on an adhoc excursion i.e. you will use it again in future, then consider purchasing the handset and paying for airtime as and when you need it.
No. Satellite phone SIM cards are tied to one number and one satellite phone handset.
We don’t often run out of satellite phone stock so, depending on location, should be able to ship by the next working day. If in doubt or placing a bulk order, feel free to give us a call and we can always confirm over the phone what our stock levels are.
All of our satellite phones come with far-reaching network coverage, however, if you need truly global reach, Iridium is the world’s only network provider that offers coverage to any location in the world
Satellite phones come with their own varying monthly contract rates. They do not explicitly carry roaming or long-distance charges as they will typically be used from far-flung locations. Please check the monthly contract rates tables on our website to get a sense of the different rates.
Yes, on our eBay website, we offer a great stock of used or ex-demo devices for very cost-effective prices.
Depending on how you intend to use your satellite phone, whether it’s in a vehicle or on a boat for example, we have a range of accessories to attach sat phones to dashboards or masts for extra portability.
Coverage varies depending on which network provider your satellite phone operates under. For example, Iridium’s network coverage is truly global, where Thuraya’s covers EMEA & APAC regions, so we advise against using Thuraya phones in the Americas and southern Africa.
It might vary from one satellite phone to another, but the general rule when dialing to a landline is to dial 00, followed by the country code, followed by the actual phone number. There may be a slight delay while the call registers.
