How to Get Wi-Fi on a Mediterranean Ferry in 2026: Step-by-Step Guide

You're on the ferry. The coast is shrinking behind you, the sea is wide and blue, and your phone just lost signal. Sound familiar?

Getting online during a Mediterranean crossing used to mean paying too much for slow, patchy Wi-Fi - or just accepting that you'd be offline for hours. In 2026, that's no longer the deal. If you're sailing on Corsica Ferries, Grimaldi Lines, or Grandi Navi Veloci, there's a much better option waiting for you.

This guide covers exactly how to get connected, which plan makes sense for your trip, and what else is on offer once you're online.

What Is Seafy Wi-Fi?

Seafy is a prepaid Wi-Fi service built for Mediterranean ferry passengers. It runs on trustworthy satellite infrastructures - which means stable, low-latency speeds even when you're well out to sea, far from any shore.

No contract. No account to create. You pick a plan, connect to the onboard network, enter your voucher code, and you're online. That's genuinely all there is to it.

Seafy is available across three major ferry operators:

• Corsica Ferries (Nice, Toulon, and Savona to Corsica and Sardinia)
• Grimaldi Lines (Civitavecchia, Naples, Salerno, and Cagliari)
• Grandi Navi Veloci* - only GNV Spirit and GNV Allegra - (Genoa, Barcelona, and Palermo)

Step-by-Step: How to Connect to Seafy Wi-Fi

Three steps. No technical knowledge needed.

Step 1. Choose Your Plan and Buy Your Voucher

You can buy your voucher before you board at seafy.com, or pick one up onboard after you've set sail.

Step 2. Connect to the Seafy Network

On your phone, tablet, or laptop, open Wi-Fi settings and connect to the network called "Seafy". The captive portal should open on its own or just open any browser and it'll appear.

Step 3. Enter Your Code and Start Browsing

Type your voucher code into the portal, hit activate, and you're live. The whole thing takes under two minutes.

Which Plan Should You Choose?

It really comes down to what you're planning to do during the crossing.

Just staying in touch?

The Easy plan at €4.99 is messaging-only — no browsing, no streaming, just texts and chats. A solid pick for shorter crossings where all you need is to check in with people back home.

Scrolling and browsing?

Digital at €8.99 gives you enough to scroll Instagram, catch up on the news, and browse comfortably. Fine for a few hours on deck with a coffee.

Streaming or juggling multiple apps?

Digital Plus at €14.99 keeps things running smoothly — light streaming, several apps open at once. Most leisure travelers land here, and it's easy to see why.

Working or on a video call?

Star Plus at €30.00 is your plan. Video conferencing, file transfers, email, full streaming — if the crossing is your office for a few hours, this is what makes that work.

What Else Does Seafy Include?

Connectivity is the main event, but it's not the whole story. Once you're through the Seafy portal, you've also got access to a set of onboard extras that make the hours at sea a lot more enjoyable:

• Live news feed real-time global updates while you're out of range of everything else
• Free games: playable directly through the portal, no downloads needed
• Radio Seafy — stations and podcasts for when you want to put the screen down and just listen

None of these come with an extra cost. They're part of the onboard experience from the moment you connect.

Planning Your Port Stop?

The crossing is a good time to figure out what you'll actually do when you arrive. Sites like Island Wayfinder are worth a look for finding local beaches, restaurants, and things to do at your destination - so you step off the boat with a plan rather than a blank itinerary.

And What About Mobile Data During the Crossing?

Once you're far enough from shore, your phone signal will be gone. That's just how it works at sea. Seafy Wi-Fi, powered by Starlink, is the reliable answer for the crossing.

Once you get far enough from the shore, you'll lose cell service.

For the parts of your trip that happen on land, especially if you're moving between countries, you might want a data option that works independently of ship Wi-Fi. Services like Holafly eSIM, Roamify, Destination SIM, and Roamfly offer prepaid international data plans that keep you covered before you board and after you arrive, with no surprise roaming charges.

Are You a Crew Member?

• One voucher, one crossing. Each plan lasts 24 hours with a set data allowance - no subscriptions, no auto-renewals, no surprises.
• Multiple devices? You'll need a separate voucher for each one you want connected at the same time.

Connect to the Seafy network and open any browser to trigger the captive portal. If it's still not working, the FAQ page at seafy.com or Seafy's support team can help you from there.

What happens to unused data?

Seafy vouchers expire 24 hours after first activation or once the data for each plan has been used up - after which any unused data is permanently lost. Unused data does not carry over to the next trip.

I have multiple devices, what should I do?

Each voucher is valid for one device only. If you wish to connect multiple devices simultaneously, you will need a separate voucher for each one.
