Docked
In port
Maps, Uber, the restaurant text. Any travel eSIM can do this. GigSky Cruise & Land does it on the same plan you used at sea, so you’re not swapping SIMs on the pier.
Does an eSIM work on a cruise?
An hour after the horn, your phone goes dark. That’s normal.
Ship Wi-Fi is the cabin. A cruise eSIM is the phone in your pocket. Here’s what actually happens at sailaway.
The horn
The dark hour
About an hour after sailaway, bars vanish. That’s the 12-mile line, not a broken eSIM. Have a drink. Walk the deck. It comes back.
Sea day
Open water
WhatsApp, mail, light photos. Interior cabins are weaker than the deck. Walk upstairs before you email support.
Updated 14 October 2026. Ship Wi-Fi is the cabin. This page is your phone.
The ship’s Wi-Fi is not your phone
The ship sells you Starlink (or whatever they branded this year) as Wi-Fi. Per device, per day. That’s the cabin — movies, Zoom, the iPad. GigSky is a phone plan. Your phone thinks it found a normal tower. WhatsApp, maps, photos. Not Netflix.
GigSky has two cruise packs that do the same job. Cruise & Land is the cheaper one most people want. Cruise + Land is the other pack, more money. Search your ship. Buy the one the app lists.
European ferries
Same idea, shorter trip. Stena, DFDS, Color Line, Brittany, Irish Ferries. A ferry-only pack starts around the price of a bad sandwich. Add Europe if you keep driving after the crossing. Ferry Wi-Fi is a lottery. The eSIM is usually the whole conversation.
Night before
Unlocked phone. Install GigSky. Buy through our link. Kill data roaming on the home SIM — maritime roaming is how people get a $400 surprise. Wait out sailaway. Do this on hotel Wi-Fi, not at the gangway.

Does an eSIM work on a cruise?
A regular travel eSIM works in port and dies about 12 miles out. A GigSky cruise eSIM stays up at sea, then local bars when you dock.
Is GigSky the same as ship Starlink Wi-Fi?
No. Starlink is the ship’s Wi-Fi — movies in the cabin. GigSky is a phone plan that works on the water, then in port. Different bill.
What is Cellular at Sea?
The name that sometimes pops up on your phone at sea. GigSky has two packs that use the ship’s own phone network. Search your ship. Buy the one the app lists. Neither is cabin Wi-Fi.
