DFDS WiFi or eSIM: get online at sea and in port
Sailing with DFDS on the Copenhagen–Oslo overnight mini-cruise, across the North Sea between Dover and Calais, or on another of the line's routes? A travel eSIM gives you mobile data on supported ships at sea, then switches to the local network when you dock. You keep your usual SIM, your number, and skip the roaming surprises.
Ferry & cruise eSIM from €12.37
What you get out of it
Stay in touch on the long crossing, sort the practical bits, and step ashore already online.
Make the most of the crossing
Check email, plan your next stop and stream a little music as the mini-cruise glides toward Oslo or across the North Sea.
Online from quay to quay
As you near Copenhagen, Oslo, Dover or Calais, your phone switches to the local network, so you're ready right away.
At sea, the connection is best for messages, maps, email and social. In port and on land you usually get a stronger local network, better suited to video and streaming.
Is there WiFi on DFDS?
Yes, DFDS ships have WiFi on board, but speed and stability can vary — especially on a busy overnight sailing or far out on the North Sea. An eSIM is a flexible alternative: it uses Telenor Maritime's maritime network on supported ships and the local network once you're in port. Your usual SIM stays in place, and the eSIM is used only for data.
Coverage and speed can vary by ship, route, distance from land and how many people are online. At sea, the connection is best for messages, maps, email and social rather than heavy streaming.

DFDS routes: data at sea and on land
On the crossing your phone uses the maritime network. In port and on land it switches to the local network, if your plan covers that country. If not, you can add a country eSIM for your destination from the same account.

How it works
Buy before you sail
Choose a plan, pay online, and get your eSIM with a QR code by email. Install it on WiFi at home or the hotel before you drive on board.
Connect automatically at sea
Once the ship is out on the crossing, your phone can connect to the maritime network on supported ships. Your normal SIM still works for calls and texts.
Online again in port
When you dock in Copenhagen, Oslo, Dover or Calais, your phone switches to the local network if your plan covers that country. If not, add a country eSIM from the same account.
DFDS eSIM — questions
Does an eSIM work on DFDS at sea?
Yes, on the covered ships. Your eSIM uses Telenor Maritime's maritime network, which provides mobile data out on the water. Your phone connects automatically once the ship is at sea. Coverage and speed depend on the ship, route and distance from land, so it's best for messages, maps, email and social.
Is an eSIM cheaper than onboard WiFi?
It depends how you travel. Onboard WiFi prices vary by ship, so check the current price with DFDS. An eSIM is one price for the whole trip with no daily charge — and it keeps working in port and on other sailings.
Does it work in port and on land?
Yes. In port and on land your phone switches to the local network. If your plan covers the country, you're online right away — whether you step off in Copenhagen, Oslo, Dover or Calais. If not, add a country eSIM for your destination from the same account.
Do I keep my own phone number?
Yes. The eSIM is data-only and sits next to your usual SIM, which still works for calls and texts on your own number.
When should I install my eSIM?
Install it on WiFi at home or the hotel before you board. It takes a couple of minutes, so you're ready before you sail.
Can I use WhatsApp, iMessage and Messenger?
Yes. Messages, calls and updates in WhatsApp, iMessage and Messenger work fine on mobile data — including at sea, where the connection is built for exactly this kind of use.
Can I stream video at sea?
Short clips may work, but speed isn't guaranteed at sea and streaming can stutter. For video or calls, the local network in port and on land is usually better. Save episodes offline for the long overnight crossing.
Which phones support eSIM?
Most newer iPhones and Android phones support eSIM — for example iPhone XS and later, and many Samsung Galaxy, Google Pixel and others. Check your phone's settings to see if it can add an eSIM.
