SIM and eSIM for cruise lines and ferries

Offer port-day data that matches the sailing. Send an eSIM voucher before travel, or sell SIM packs at the terminal and on board.

Short answer: Offer a RoamWorks port-day plan that matches the sailing. The guest installs an eSIM before travel, or buys a SIM pack at the terminal or in the onboard shop. It works ashore in the listed countries. It does not cover the open sea.

Last updated 28 October 2026 · Reviewed by Roamworks
Does an eSIM work on a cruise ship at sea?

No. A RoamWorks plan uses land networks in the listed countries, so it works in port and ashore. Ship Wi-Fi is the service at sea.

Can one plan cover the itinerary?

Yes, if a regional plan lists every port country. Add a local plan for a gap.

Will it replace onboard Wi-Fi?

No. It covers port days and the pre-cruise hotel.

Can we sell SIM packs on board?

Yes. Stock packs for the port countries in the onboard shop. Check that each guest phone is unlocked.
