"Satellite phones are expensive."
It's one of the biggest misconceptions in satellite communications.
Yes, a satellite phone costs more upfront than the average smartphone. But once you look beyond the purchase price, the ongoing costs are often far lower than people expect.
Let's break it down.
First, You'll Need the Phone
The biggest cost is usually buying the handset itself, but unlike smartphones, satellite phones aren't designed to be replaced every two years.
They're built to survive years of adventures, expeditions, offshore work and harsh environments, making them a long-term investment rather than a regular upgrade.
At OSAT, prices currently range from $525 for entry-level regional models through to $1,344 for premium global satellite phones.
Some popular examples include:

Airtime Doesn't Have to Cost Hundreds Every Month
This is where most people are pleasantly surprised. Many buyers assume satellite phones work like a cellphone contract. They don't. You have two straightforward options: prepaid airtime or monthly service plans.
Occasional User? Prepaid Is Usually the Cheapest Option
If your satellite phone lives in an emergency kit, sailing bag or overlanding vehicle, prepaid airtime is often all you need.
For example:
-
An Inmarsat Sub-Saharan prepaid voucher starts from $16, giving occasional users an affordable way to stay connected.
-
Entry-level Iridium prepaid vouchers start at $64, offering global coverage for users who only head off-grid a few times each year.
There are no monthly bills while you're not using the phone, you simply top up when you're ready for your next trip.
Regular User? Monthly Plans Can Offer Better Value
If your satellite phone is used every week for work, research or offshore operations, a monthly plan often makes more financial sense.
As a guide:
-
Iridium monthly plans start from $63 per month.
-
Inmarsat monthly plans start from $66 per month, making them one of the most affordable options for regular users operating outside the polar regions.
-
Thuraya post-paid SIMs are available from $37.50 per month, providing an economical solution within Thuraya's regional coverage footprint.
For businesses with multiple users, monthly billing also makes budgeting much easier.
Real-life examples
So... What Does That Look Like in Real Life?
Let's imagine three different satellite phone owners, each with a very different usage pattern and budget.
01
The Weekend Adventurer
Sarah hikes a few times each year and wants a reliable emergency backup whenever she ventures beyond cell coverage.
She chooses an IsatPhone 2 and activates prepaid airtime before each major trip.
Apart from the occasional top-up, she has virtually no ongoing monthly costs.
02
The Offshore Sailor
Mike keeps an Iridium Extreme onboard throughout the sailing season.
He uses it for routine check-in calls and weather updates while offshore.
A monthly airtime plan gives him predictable costs and complete peace of mind.
03
The Remote Contractor
Jess works in isolated locations every week where dependable communications are essential.
Her Iridium 9555 is effectively another business phone.
A monthly plan is the obvious choice because it's in regular use throughout the year.
Three different users. Three completely different budgets.
The right combination of handset and airtime depends entirely on how often, and where, you need to stay connected.
The Biggest Mistake? Buying the Wrong Airtime
Most people don't overspend on their handset, they do so by choosing an airtime plan that doesn't match how they actually use their phone. If you head off-grid twice a year, a large monthly package probably isn't necessary. If you're making calls every day, constantly topping up prepaid vouchers quickly becomes frustrating.
That's why we always recommend choosing the network and airtime plan together, not separately.
