Stena Line WiFi or eSIM: stay online at sea and in port
Sailing Stena Line from Gothenburg to Frederikshavn, Gothenburg to Kiel or Karlskrona to Gdynia? A travel eSIM gives you mobile data on supported ships at sea, then hands over to the local network the moment you dock. Your usual SIM stays put — same number, no roaming surprises.
Ferry & cruise eSIM from €12.37
Why an eSIM pays off
Stay reachable, get the practical bits sorted, and land ready to go.
Get the small stuff done
Answer a mail, pull up a booking or check the map while the ferry crosses.
Sorted the moment you dock
As you come alongside, your phone moves to the local network, so you roll off the ramp already online.
At sea the connection is best for messages, maps, mail and social. In port and on land you usually get a stronger local network — better for video and streaming.
Is there WiFi on Stena Line?
Yes — Stena Line ships have WiFi on board, and it's fine for a quick check. But on a packed sailing or well out in the Kattegat or Baltic it can slow down. An eSIM runs alongside it: on supported ships it uses Telenor Maritime's maritime network at sea, then the local network once you're docked. Your normal SIM stays in the phone; the eSIM only carries data.
Coverage and speed vary by ship, route, distance from land, network and load. At sea it's best for messages, maps, mail and social rather than heavy streaming.

Stena Line routes: data at sea and on land
Whether you cross Gothenburg–Frederikshavn, Gothenburg–Kiel, Karlskrona–Gdynia or Grenaa–Halmstad, your phone uses the maritime network at sea and the local network in port — as long as your plan covers that country. If it doesn't, add a country eSIM for your destination from the same account.
Add a country eSIM for where you're sailing to:
How it works
Buy before you board
Pick a plan, pay online and get your eSIM as a QR code by email. Install it on WiFi at home or your hotel before you drive into the terminal.
Connect automatically at sea
Once you cast off, your phone can join the maritime network on supported ships. Your normal SIM still handles calls and texts.
Online again in port
As you dock, your phone switches to the local network if your plan covers the country. If not, add a country eSIM from the same account.
Stena Line eSIM — questions
Does an eSIM work on Stena Line at sea?
Yes, on the covered ships. Your eSIM uses Telenor Maritime's maritime network for mobile data out on the water, and your phone connects automatically once you're at sea. Coverage and speed depend on the ship, route and distance from land, so it's best for messages, maps, mail and social.
Is an eSIM cheaper than Stena Line's onboard WiFi?
It depends how you travel. Onboard WiFi prices vary by ship and fare, so check the current price with Stena Line. An eSIM is one price for the whole trip with no daily charge — and it keeps working in port and on your next sailing.
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 that country — Sweden, Denmark, Germany or Poland — you're online right away. 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 alongside your usual SIM, which still handles calls and texts on your own number.
When should I install my eSIM?
Install it on WiFi at home or your hotel before you reach the terminal. It takes a couple of minutes, so you're ready before departure.
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. Download episodes before you sail.
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.
Sailing Stena Line? Get your eSIM ready before departure
Install your eSIM on WiFi before you go, keep your own number, and get data both on supported crossings and once you're ashore.
