Does roaming work on ferries to and from Denmark?
Mobile use at sea
Short answer
EU roam like at home applies on a ship only when your phone is connected to a land-based mobile network, for example close to the coast or in a harbour. Ferries and cruise ships often use satellite connections, also inside EU waters, and these are not covered by the EU price caps. Satellite roaming can lead to large bills. Many operators block satellite data by default, but the block covers data only, not calls or texts.
Why
- Home prices apply only on land-based networks.
- Ships often switch to satellite at sea.
- Satellite use has no EU price cap.
Details
The same rule applies on planes: a land-based network gives home prices, a satellite service does not.
Tip
Switch on flight mode or turn off roaming when the ferry leaves the harbour, and use the ship's wifi if you need data.
What may differ
Whether your operator blocks satellite data by default depends on the operator.
Common misconception
Many people think a ferry between two EU countries is always covered by EU roaming.
What actually happens
Only land-based networks are covered; satellite on board is not, even in EU waters.
