eSIM for a cruise itinerary
There is no land network at sea, so an eSIM mainly works when the ship is in port.
Author: eSIMonline Travel Desk · Travel content desk
Quick answer
- Pick a regional plan covering every country the ship calls at.
- Turn cellular off at sea so the phone does not attach to the ship's satellite network.
At sea the ship's onboard network is a separate satellite service billed by the cruise line, usually at very high rates, and is not part of your eSIM plan.
Plan your data around port days
Do the heavy things — photo uploads, video calls — while the ship is docked and you are ashore, which is when the eSIM behaves normally.
