Color Line WiFi or eSIM: get online on the crossing
Sailing with Color Line on Oslo–Kiel, Sandefjord–Strömstad or Kristiansand–Hirtshals? A travel eSIM gives you mobile data on supported ships at sea, then switches to the local network when you reach port. 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, handle the practical bits, and make better use of the crossing.
Make good use of the time
Check email, open documents and get the small things done while you sail.
Ready when you step ashore
As you near port, your phone can switch to the local network, so you're online for the rest of the trip.
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 Color Line?
Yes, Color Line ships have WiFi on board, but speed and stability can vary — especially on busy sailings or further out to 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.

Color Line 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.
Add a country eSIM for where you're sailing to:
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 board.
Connect automatically at sea
Once the ferry 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 reach land, your phone switches to the local network if your plan covers that country. If not, add a country eSIM from the same account.
Color Line eSIM — questions
Does an eSIM work on Color Line 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 ferry 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 Color Line. 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. 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 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.
