Using your SIM at Sea - Maritime usage explained

Travelling offshore? Here's how Maritime services work

Written by Casey

What is Maritime roaming/usage?

Maritime network services exist so that you can stay connected when you're at sea (such as on a ship, cruise or boat) as they are too far from land to use regular mobile phone towers (masts). 🚢

Maritime networks use Satellites, which are like giant Wi-Fi routers in space! 🛰️


What's the cost of Maritime rates?

🚨

Maritime roaming rates are higher than roaming rates on land destinations.

To help avoid unexpected costs, we recommend connecting to the ship/cruise/vessel Wi‑Fi where available.


How do I get connected?

Just like roaming outside of EU destinations, you'll need an out of plan add-on to use maritime roaming.

How will I know if I'm using maritime services?

There are a few easy ways to tell when your device has connected to a maritime network 👇

📱Check the network name on your device

  • Your phone will display a different network name than a standard land-based mobile network (like Vodafone, Three or local partners)

  • You may see names that include terms like 'Maritime', 'Ship' or vessel name, 'Satellite'

🌊You're outside of normal signal areas

  • If you're at sea, on a boat, cruise, ferry or in a very remote location, it's very likely you're connected to a maritime service rather than a standard land-based network.

💬 You'll receive a message

  • You'll get a text message alert when you connect, letting you know you're roaming on a maritime network and charges will apply.


Recap: Things to keep in mind 💡

  • You'll need an out of plan add-on to get connected

  • Costs are higher than standard international roaming

  • Charges apply for calls, texts and data

  • Connections can sometimes be slower or less stable than normal mobile networks.
