The Iridium GO! is a compact satellite communications hub that lets you use your smartphone or tablet for voice calls, messaging and basic data anywhere the Iridium network can reach. Up to five devices can connect over Wi-Fi, making it a practical choice for families, crews and small teams travelling beyond cellular coverage. It’s best suited to calls, texts and essential off-grid communication rather than conventional internet browsing.
The Iridium GO! exec is a more advanced satellite communications terminal built for users who need both reliable voice and practical data connectivity off-grid. Powered by Iridium Certus 100, it supports voice calls, email, messaging and selected online services, with faster data than the original GO! and connectivity for smartphones, tablets and laptops. Its touchscreen, Wi-Fi and Ethernet options make it especially useful for offshore trips, remote work and longer expeditions.
Satellite hotspots are particularly useful on the water because they let you use familiar devices such as smartphones, tablets and, with more capable terminals, laptops.
The Iridium GO! is a solid option for crews that mainly need voice calls and messaging, while the GO! exec adds more capable data access for email, weather information, messaging and other lightweight online services.
Position the terminal where it has a good view of the sky and your crew can stay connected from places where ordinary cellular service simply isn’t an option.
It isn’t about turning the boat into a floating office. It’s about having a dependable way to communicate, coordinate and get important information through when you’re a long way from shore.
Satellite coverage isn’t tied to distance from the coastline in the way cellular coverage is. A device using the Iridium network can remain connected far offshore, including across open ocean, provided the terminal has a suitable view of the sky.
The terminal itself generally performs best somewhere with a clear view of the sky. Metal cabins, roofs and other parts of the vessel can block the satellite signal, so many users position the unit on deck or in another open location while connecting to it wirelessly from nearby.
For more permanent installations, external antenna options may be worth considering depending on the device.
Yes, particularly with a data-capable device such as the Iridium GO! exec. Lightweight weather information, forecasts and other essential data can be practical over satellite.
Large graphical downloads and bandwidth-heavy weather services may be less suitable, so it’s worth using apps and services designed with low-bandwidth connections in mind.
No. VHF and satellite communications serve different purposes and can complement each other.
VHF is extremely useful for contacting nearby vessels, marinas and coastal services, while a satellite hotspot gives you a way to communicate over much greater distances. For offshore trips, having more than one method of communication can be very useful.
Yes. Satellite hotspots can support multiple connected devices, which makes them practical for couples, families and crews sharing one connection.
Rather than carrying several separate satellite phones, different people can use their own compatible devices for calls, messaging or data depending on the terminal and service being used.
Not in the same way as cellular or broadband internet. It’s designed for essential communications such as email, messaging, weather information and selected online services rather than streaming, video calls or large downloads.
For offshore use, that can actually be an advantage because the focus stays on the services you’re most likely to need rather than bandwidth-heavy applications.
