GTC Satellite Buying Guide
Pick the right device first time. Explore guides for phones, hotspots, tracking, and airtime, plus practical tips that reduce cost, confusion, and risk.
A clearer way to choose the right satellite solution
Buying satellite equipment can feel more complex than it needs to be. Coverage, airtime, intended use, and hardware type all matter, and getting one of those wrong can lead to overspending or ending up with a device that does not actually fit the job.
This guide hub is designed to make the process easier. Use it to compare your main options, understand where each category fits best, and jump straight into the buying guide that matches your project.

Quick answers
The questions people usually ask before they check out.
Satellite Phones
Satellite phones are the straightforward choice when dependable voice calls and SMS are the priority. They are especially useful for remote travel, emergency preparedness, field operations, marine use, and situations where mobile coverage cannot be trusted.
The right handset depends on where you are going, how often you plan to use it, and whether you need a simple backup tool or something that will be used regularly as part of your workflow.
Top tip: For short trips or occasional use, renting can often be the smarter option because it keeps costs and admin down while still giving you full satellite capability.
Hotspots and Internet
Satellite hotspots are designed for users who need more than just emergency calling. They allow laptops, tablets, and other connected devices to get online beyond the reach of terrestrial coverage, making them useful for remote work, expeditions, media teams, vessels, and operational field deployments.
Top tip: Messaging and email are light, while video, large uploads, and multiple connected users can consume far more capacity than expected. Coverage and line of sight matter just as much as the device itself.
Tracking and SOS
Satellite trackers and communicators are ideal when location visibility, check-ins, and emergency alerting matter more than regular voice calls. They are a strong fit for lone workers, expeditions, safety-conscious travellers, asset visibility, and teams that need reassurance without the complexity of a full phone solution.
Some devices focus on simple tracking and SOS, while others add two-way messaging and wider monitoring capability. Deciding which level you need early makes the whole selection process much easier.
Top tip: Work out whether simple tracking and emergency alerting is enough, or whether two-way messaging is important to your use case.
Airtime and SIMs
Airtime determines how your satellite device actually works in practice, and it is often the part buyers overlook until too late. The right plan can help control spending, match usage properly, and avoid paying for capacity you do not really need.
For some users, a prepaid setup makes most sense. For others, a monthly contract is more practical. The best choice depends on frequency of use, expected call or data demand, and whether the device is being used seasonally, occasionally, or as part of routine operations.
Top tip: If your use is seasonal or occasional, choose a plan style that scales sensibly instead of locking yourself into higher monthly costs year-round.

Frequently Asked Questions
Do I need airtime for every satellite device?
Phones and data devices typically require airtime. Some SOS devices rely on subscriptions for features like tracking and messaging. If in doubt, treat airtime as part of the total cost, not an optional extra.
What should I check about coverage?
Check that your destination is served by the network your device uses. For example, Thuraya devices are not suitable for operation in the Americas. Iridium and Inmarsat provide global and near-global coverage respectively.
Rent or buy?
Renting suits short trips, projects, and one-off deployments. Buying suits regular use, teams, and longer-term planning. The phone guide can help you decide quickly.
How do I avoid spending too much on airtime?
Estimate realistic usage, then choose the plan style that matches it. Set behaviour rules for data use and avoid overbuying capacity just in case when your use is only occasional.
Can you help me choose?
Of course. Our product experts are always happy to help. Simply call or email and we can advise on the best device for your needs.
