Get GigSkyBest eSIM for cruise ships
The best eSIM for cruises is the one that still has bars after the 12-mile line. Regular travel eSIMs die there. GigSky does not — on 290+ ships.

Updated 14 October 2026. We send most people to GigSky. Maya, Saily, and eSIM.dog when they fit the sailing.
We’re not ranking 40 brands. Most of them are land eSIMs wearing a cruise headline. You want bars on a sea day, then Uber in Cozumel, without buying two products. That’s a short list.

Get GigSkyFive eSIMs actually stay up after the horn. Everything else — including products named “cruise” that only mean ports — dies about 12 miles out.

Best sea-day price
Cheaper per gigabyte at sea. No land included. Fine if you will buy a second eSIM for Nassau and Cozumel. Most people will not, and then they’re mad on the pier.
Get Saily · 20% offCheapest Cunard / ferry start
100 MB from $14.49 on Cunard, Viking, Costa, P&O, AIDA, Stena, DFDS. Sea only. 5% off with DUDEADVICE5. Not the play for Royal or Disney.
Get eSIM.dog · 5% offUnlimited-style runner-up

One eSIM for the ship and 165+ countries. Fast until you stream a movie, then it slows. Check your ship on Maya. 10% off with ESIMTWEAKS10.
Get Maya · 10% offBest for cabin movies
Still wins if every person in the cabin will stream. An eSIM is a phone plan, not a Netflix plan. Say that out loud before you skip VOOM or Disney’s $49 package.
It does not mean Airalo, Holafly, Nomad, or your home carrier roaming. Those are land products. Once the ship is twelve miles out there are no land towers. That’s the whole product. If a site calls them a cruise eSIM without that asterisk, close the tab.
Red Bull MOBILE Maritime is cheap on some Cunard, P&O and Viking sailings in Europe. Useful on a Cunard or a ferry-adjacent run. Not the default for a Caribbean week. OneRoam is unlimited by the day — handy if you hate counting gigs, pricier than GigSky’s 5 GB week after ESIMDUDE.
Port-only, so they do not belong in this list: Airalo, Holafly, Nomad, Saily country packs, Your home carrier — that’s the $400 bill.
Caribbean or Alaska week: Cruise & Americas. Med week: Cruise & Europe. World cruise: Cruise & World. Ferry to Ireland: the ferry pack, plus land if you keep driving. Open our GigSky link on all of them.
GigSky Cruise & Land, if you want one plan for sea days and ports. Regular travel eSIMs die 12 miles out. Ship Starlink Wi-Fi still wins for cabin Netflix.
In port, yes. At sea, no. There are no land towers past about 12 miles. Airalo, Holafly and Nomad are port plans.
GigSky if you want your ship listed by name and sea plus port on one eSIM. Maya if you want one plan that doesn’t count gigabytes and GigSky doesn’t list the ship. Saily if you only care about sea days and will buy a second plan for the islands.
