GigSky — Full Guide 2026
eSIM & Internet · Our commission: 20% of the plan price, or a fixed $2–$10 per plan.
GigSky is an eSIM data provider with a special strength: it works not only on land, but also on cruise ships and on some flights. Most travel eSIMs stop working when you leave the shore or get on a plane — GigSky has plans made for cruise passengers and for in-flight data, so you can stay online in places where other eSIMs cannot reach. On land, GigSky offers data plans for more than 190 countries, with local, regional and global options, and it works with several airlines and cruise lines directly. If your trip includes a cruise or a long flight, GigSky is worth a close look.
TL;DR — The Short Version
What it is: an eSIM provider for land, sea and air. Best for: cruise passengers and travellers who want data on a plane. Coverage: 190+ countries on land, plus cruise and in-flight plans. How it works: buy a plan, install the eSIM, activate when you need it.
What is GigSky?
GigSky started by providing data for connected devices and grew into travel eSIMs, and that background shows in its coverage: the company works with mobile networks around the world, and with airlines and cruise companies, to offer data in places other providers do not reach.
A cruise plan gives you internet on the ship and in the ports you visit, without the very high prices cruise lines usually charge for Wi-Fi. An in-flight plan gives you data on supported flights, so you can message and browse instead of paying the airline's expensive Wi-Fi.
On land, GigSky works like any other eSIM: choose your destination, pick a plan, install it from the app, and turn it on when you arrive. Your home SIM stays in the phone for calls and texts.
What You Can Book With GigSky
Here is what you can book with GigSky:
- Local eSIMs: data plans for one country, for trips of a few days or a few weeks.
- Regional eSIMs: one plan covering a region such as Europe, Asia or the Americas.
- Global eSIMs: data for many countries on one plan, for round-the-world trips.
- Cruise plans: data that works on the ship and in port, without the cruise line's high Wi-Fi prices.
- In-flight plans: data on supported flights, so you can stay online in the air.
How to Book With GigSky — Step by Step
- Check your phone supports eSIM — most modern iPhones and Android phones do.
- Open GigSky through our link and choose your plan: a country, a region, a cruise plan, or an in-flight plan.
- Pay by card and install the eSIM from the GigSky app.
- Turn the eSIM on when you need it — when you land, when you board the ship, or when your flight takes off.
- Top up in the app if you run out of data during your trip.
Who Is GigSky Best For?
GigSky is best for cruise passengers and frequent flyers — the two groups other eSIMs serve worst. If you are going on a cruise, a GigSky cruise plan is usually much cheaper than the ship's own Wi-Fi, and it works in port too.
If you fly often and want data in the air, the in-flight plans are worth checking. For a normal land trip, GigSky is a solid choice alongside Airalo and Yesim: compare the price for your destination, because the cheapest provider changes from country to country.
If your trip is only on land and you want the lowest price, compare all three before you buy.
Cruise Wi-Fi Is Expensive — GigSky Is the Cheaper Fix
Anyone who has been on a cruise knows the problem: the ship's Wi-Fi is slow and expensive, often $15–$25 per day, and it sometimes stops working when the ship is far from shore.
A GigSky cruise plan gives you data on the ship and in the ports for much less, and you keep the same eSIM for the whole trip — land and sea. That matters because a cruise is not only the ship: you also want maps, messages and ride-hailing in every port you visit.
With a cruise plan, you do not buy a new SIM in each port, and you do not pay the ship's daily Wi-Fi fee.
Before you buy, check that your cruise line and ship are supported, and check how much data the plan includes — video calls and streaming use data fast, so buy a bigger plan if you work online from the ship.

- Compare GigSky with Airalo and Yesim for land-only trips — the cheapest one changes by country.
