Brittany Ferries provide complimentary access to the internet on board all their ferries as well as an enhanced service on board Cap Finistère and Pont-Aven (enhanced service payable). Note: The Wi-Fi is provided by satellite so it won't be as fast as you would expect at home or work.

As of 2026, Brittany Ferries provides Wi-Fi across its entire fleet, including in the cabins, but the quality and speed can vary. The airline offers a free "Surf Free" package (usually 60–90 minutes depending on the route) for basic browsing and messaging. For those needing a stronger connection inside their cabin, "Enhanced Wi-Fi" packages are available for a fee, typically ranging from €3.50 for one hour to €25 for an "unlimited" sailing pass. Because the signal is provided via satellite, it is not as fast as home fiber; it is generally sufficient for social media and email but can struggle with high-definition streaming. In 2026, the newer E-Flexer ships like the Salamanca and Santoña have more robust internal antenna systems, making the Wi-Fi much more reliable in the lower-deck cabins. "Pro-tip": Turn off "Auto-Updates" and put your phone in "Low Data Mode" to make your Wi-Fi minutes last as long as possible during the crossing.
