GigSky vs cruise ship Wi-Fi
Prices last confirmed
Short answer
For two people on a seven-night sailing, the eSIM wins by a wide margin. Ship Wi-Fi is priced per device per day, so a couple pays for fourteen device-days — $420 on Disney Cruise Line, $223.86 on MSC Cruises. One GigSky Cruise + Land plan at $29.99 covers the same week, shares over a hotspot, and keeps working in port.
Ship Wi-Fi still wins in three cases: you are travelling alone and need to work properly, the itinerary is nearly all sea days, or your fare already includes it. Check your booking confirmation before you buy anything: a fare that already includes Wi-Fi settles the question on its own.
Seven nights, line by line
These are the day rates on each line’s own row in our catalogue — the same figures the individual cruise-line pages render, re-verified on the schedule described in how we test. The eSIM column is one Cruise + Europe 1GB plan at $29.99, which is what a week costs whether one person uses it or four. The same day rates, ranked with a stated methodology and free to reuse, are published as the Cruise Ship Wi-Fi Price Index.
| Cruise line | Wi-Fi / device / day | 7 nights, 1 device | 7 nights, 2 devices | Saved with one eSIM |
|---|---|---|---|---|
| Disney Cruise Line | $30 | $210 | $420 | $390.01 |
| Norwegian Cruise Line | $29.99 | $209.93 | $419.86 | $389.87 |
| Royal Caribbean | $26.99 | $188.93 | $377.86 | $347.87 |
| Princess Cruises | $25 | $175 | $350 | $320.01 |
| Carnival Cruise Line | $20.40 | $142.80 | $285.60 | $255.61 |
| Celebrity Cruises | $20 | $140 | $280 | $250.01 |
| MSC Cruises | $15.99 | $111.93 | $223.86 | $193.87 |
| GigSky Cruise + Europe 1GB | — | $29.99 | $29.99 | — |
Day rates are the onboard price. Most lines discount 10–20% for pre-purchase and some quietly double the device allowance if you buy before you sail — if you are going to buy the package, buy it early. The eSIM figure is a single purchase, not a per-day rate.
Why “per device” decides this
Almost every argument about cruise internet costs is really an argument about this one word. A cruise Wi-Fi package is a licence for one device to be online for one day. Add a second phone and you pay again; add a tablet for the children and you pay a third time. A family of four on Disney Cruise Line at $30 a day is looking at $840 for a week of internet.
A maritime eSIM is the opposite shape. It is a data allowance on one phone, and personal hotspot works at sea exactly as it does at home — so one purchase serves a cabin. That is not a loophole the providers tolerate reluctantly; GigSky documents tethering as a normal use of the plan. The practical effect is that the eSIM’s advantage grows with every extra person, while the ship’s package gets worse.
The counter-argument is real and worth stating: a shared 1 GB allowance is a shared 1 GB allowance. Four people uploading photos will finish it in a day. If you genuinely need volume rather than connectivity, the honest comparison is the ship’s package against a larger eSIM plan, not against the cheapest one.
What the ship’s Wi-Fi does better
Starlink changed this comparison and it would be dishonest to pretend otherwise. Until 2023 cruise Wi-Fi ran through geostationary satellites 35,000 km up, and the 600 ms round trip made video calls impossible. Starlink orbits at about 550 km, bringing latency to roughly 80–90 ms. On an upgraded ship the Wi-Fi is genuinely fast.
A maritime eSIM is not. It runs on the ship’s cellular network, typically 700 Kbps to 4 Mbps — comfortable for messaging, maps, email, banking and social, unreliable for sustained video. It also cannot serve a laptop without tethering, and it cannot serve a working day.
- You are working from the ship. If a dropped call costs you a client, buy the package — and buy the tier that permits VPN, because the basic tiers on several lines block it outright.
- The itinerary is nearly all sea days. A Cunard transatlantic crossing is seven consecutive days with no port call, and long-voyage package rates fall sharply — on a crossing the ship’s full-voyage price can beat a week-sized eSIM.
- Multiple laptops. Two people working from two laptops is the one configuration where two device passes are simpler and better than one hotspot.
What the eSIM does better
Beyond price, three things. It works in port — the ship’s package stops at the gangway on most lines, and GigSky’s Cruise + Land family switches to local networks ashore on the same plan. It is bought once, so there is no daily decision about whether today is worth $30. And it is testable before you pay: the free 100 MB trial is the only way to confirm your specific hull is covered, because maritime equipment is fitted vessel by vessel rather than fleet by fleet.
It also sidesteps the contention problem. Everyone aboard shares the ship’s single satellite link, which is why Wi-Fi speeds collapse after dinner and on sea days. The cellular side is a separate system with its own capacity, so a busy evening affects it far less.
The two lines where you should buy nothing
Viking and Virgin Voyages include Wi-Fi in the fare, and on those ships we would not sell you anything for sea days. Viking includes it for every guest with no paid upgrade currently sold; it is fair-use limited and asks you not to stream, and within those limits it is genuinely free. Virgin Voyages includes a basic tier for every Sailor — but on one device per person, with streaming and video calls blocked, so “free Wi-Fi for all” and “the Wi-Fi you were imagining” are not the same product.
On both, buy a regional eSIM for the ports, where the ship’s Wi-Fi does not reach and where you will actually want speed. That is the whole purchase.
What we would actually do
Two people, seven nights, a normal port-and-sea itinerary: one GigSky Cruise + Land plan, shared over a hotspot, and nothing from the ship. That is $29.99 against $223.86 at the cheapest line in the table above.
One person who has to work: the ship’s package at the tier that allows VPN, plus a cheap regional eSIM for port days. Do not buy a maritime eSIM as well — it will not carry the working day and you will have paid twice.
A family of four: the eSIM, on a larger allowance than you think you need, and airplane mode enforced on the children’s phones. Four device passes is the single most expensive way to solve this problem.
A crossing or a world cruise: price the ship’s full-voyage package properly before assuming the eSIM wins. This is the itinerary type where it often does not.

GigSky vs ship Wi-Fi FAQ
01Is a cruise eSIM cheaper than the ship’s Wi-Fi?+
For two or more people, almost always. Ship Wi-Fi is billed per device per day, so a couple on a seven-night sailing pays for fourteen device-days — roughly $220 to $420 depending on the line. One shareable maritime eSIM covers the same week for about $35 and keeps working ashore. For one person who needs to work properly from the ship, the package is usually the better tool.
02Can I share a cruise eSIM over a hotspot?+
Yes, and that is the whole cost argument. A maritime eSIM is a data plan on your phone, so personal hotspot works exactly as it does at home — one purchase covers a cabin. Ship Wi-Fi packages are sold per device and most lines actively enforce the limit, which is why the second traveller doubles the price rather than adding a few dollars.
03Is the ship’s Wi-Fi faster than a cruise eSIM?+
On a Starlink-equipped ship, yes. Starlink brought latency from roughly 600 ms down to about 80–90 ms, which is close enough to home broadband for video calls. A maritime eSIM runs on the ship’s cellular network, typically 700 Kbps to 4 Mbps. Fine for messaging, maps, email and social; not the tool for a full working day.
04Do I still need an eSIM if I buy the ship’s Wi-Fi package?+
For port days, usually yes — the ship’s package stops at the gangway on most lines, and it is the worst-value data you can buy for a day ashore. A cheap regional eSIM covers port days for a few dollars. That combination, minimal ship Wi-Fi for sea days plus regional data ashore, is the cheapest setup for a port-heavy itinerary.
