Wi-Fi on Grimaldi Lines Ferries: Prices and How It Works

We’ve already addressed the question of whether cell phones work on ferries, explaining how to use the internet at sea without risking unpleasant surprises on your bill (link at the bottom). This time, we want to focus on another aspect that’s of particular interest to those traveling by sea: the ability to browse the Internet during the crossing using the onboard Wi-Fi on Grimaldi Lines ferries.

In particular, we’ll take a closer look at the service offered by Grimaldi Lines through its Seafy packages, analyzing costs, how to access the service, and the features of the integrated digital platform. Staying connected during the trip is an increasingly important need, but it’s also a source of concern for many passengers, who fear ending up with a particularly high phone bill due to maritime roaming charges.

So let’s take a look at how Wi-Fi works on Grimaldi Lines ferries, how much it costs, and what options it offers travelers.

Is Wi-Fi available on Grimaldi Lines ferries?

Yes, Grimaldi Lines offers passengers a paid satellite Wi-Fi service, accessible through the Seafy network. The connection is available in the interior areas of the ships and allows passengers to use the Internet while at sea, without having to rely solely on land-based cellular network coverage.

The service has been gradually expanded, and Grimaldi Lines and Seafy have completed the rollout of the new digital platform to all 13 ships in the passenger fleet.

Internet access is not included in the ticket price: to use it, you must purchase one of the available packages separately, choosing the one that best suits your browsing habits.

It is important to remember that satellite Wi-Fi may be subject to technical limitations. Connection quality also depends on weather conditions and the ship’s location during the voyage. Therefore, it is not always possible to guarantee the same speed or uninterrupted service.

How much does Wi-Fi cost on Grimaldi Lines ferries?

Seafy offers four Wi-Fi packages, categorized by usage type and the required connection speed. The published rates are as follows:

Easy – €4.99

This is the most affordable plan, designed for those who mainly want to use messaging apps and stay in touch with friends and family while traveling.

Digital – €8.99

A solution for those who also want to use social media, access online content, view photos, and browse the Internet with greater freedom.

Digital Plus – €14.99

It is recommended for users who run multiple applications at the same time and also want to access light streaming content.

Star Plus – 30 €

This package is designed for users with higher connectivity needs. It allows for more intensive Internet use, including video conferencing, video content, and other activities that require higher performance.

The choice therefore depends on how much you use the Internet during the crossing. The Easy package may be sufficient for sending messages and staying in touch with family members, while those who want to work online or use more digital services may want to opt for the higher-tier plans.

The fares listed are those published by Seafy and are subject to change. Before purchasing, we recommend checking prices and terms on the official Seafy portal dedicated to Grimaldi Lines.

On which Grimaldi Lines routes is Seafy Wi-Fi available?

The Seafy Wi-Fi service is available to passengers on Grimaldi Lines ferries in the Mediterranean, with destinations in Sardinia, Sicily, Spain, Greece, and Tunisia. Actual availability of the connection depends on the ship assigned to the crossing and can be checked during the booking process.

Among the Grimaldi Lines routes you can view on FerryFinder are:

Ferries to Sardinia

Connections to Sicily

Palermo – Salerno

International Connections

How to Get Wi-Fi Before You Leave

To avoid having to complete all these steps once you’re on board, you can purchase your package through the Seafy portal before departure.

The process is simple: just go to the official Seafy portal dedicated to Grimaldi Lines, select the Grimaldi Lines Wi-Fi service, choose the package you want, and complete the payment.

Available payment methods include credit and debit cards, Apple Pay, Google Pay, and Revolut Pay.

Once the purchase is complete, you will receive the voucher needed to activate the connection. The code must be entered through the Seafy portal while you are on board the ship.

How to Connect to Wi-Fi on Grimaldi Lines Ferries

Once you’re on the ferry, connecting to the Internet through Seafy takes just a few steps. You don’t need to download a dedicated app—you can access it directly from your device’s browser.

Here’s how to proceed:

Turn on Airplane Mode on your smartphone or tablet.
Turn Wi-Fi back on in your device’s settings.
Select the Seafy wireless network from the available networks.
Open your browser and go to the onboard portal, or wait to be automatically redirected.
Enter the voucher you purchased earlier and follow the instructions to activate the package.
After activation, you’ll be able to use the Internet according to the terms of the plan you purchased.

Airplane mode is important because it allows you to disable the connection to cellular networks, preventing your smartphone from accidentally connecting to maritime roaming. In fact, Wi-Fi can still be turned on even when airplane mode is enabled.

Seafy: The Digital Wi-Fi Platform on the Ferry

One of the major changes introduced in 2026 concerns the evolution of the Seafy service, which has gone from being a simple Wi-Fi portal to a full-fledged Digital Experience Platform.

The service, which has been rolled out on all 13 ships in the Grimaldi Lines fleet, aims to integrate connectivity, information, and digital services into a single platform accessible to passengers.

Through the portal—which can be accessed from smartphones, tablets, and other devices without installing any apps—travelers can connect to the Internet. The platform is also designed to gradually integrate new entertainment features and in-flight services.

The technological upgrade also addressed connection performance, with the goal of improving stability and speed. Contactless payment systems, including Apple Pay, Google Pay, and Revolut Pay, have also been introduced to make it easier to purchase services directly from a smartphone.

This initiative represents an evolution of the in-flight digital experience: Wi-Fi is no longer just a tool for browsing the web, but also serves as a gateway to the information and features provided by the airline.

Wi-Fi or maritime roaming: Internet on the ferry without unexpected charges

As the ferry moves away from the coast, your smartphone may lose its connection to land-based cell towers and switch to a maritime cellular network. This connection, which uses communication systems installed on board, can result in particularly high charges.

Please note: Maritime roaming is not necessarily included in standard phone plans, even when traveling within the European Union. It is therefore advisable to check the terms and conditions of your carrier before departure.

Seafy’s satellite Wi-Fi offers an alternative with a fixed price, since it allows you to purchase a package without using your SIM card’s data allowance via the maritime network.

To avoid unexpected charges, we recommend turning on Airplane Mode and using only Wi-Fi while browsing.
