GigSky review
GigSky is one of very few travel eSIMs that works at sea. Its cruise plans bundle ship-based satellite-backed connectivity with port coverage in a single purchase, which is why it is our recommendation for anyone sailing rather than flying.

Background
Who is behind GigSky?
GigSky is a US-based mobile data provider that has been in the travel connectivity business far longer than most of the eSIM startups, with device-maker partnerships behind it.
That longevity is why it has agreements in place — including maritime — that newer entrants have not managed to sign.
Cruise
How at-sea coverage actually works
Cruise plans connect through maritime networks while the ship is at sea, then hand over to local carriers when you are in port. It is one purchase covering both states.
It is not fast broadband. Expect messaging, email, maps and light browsing to work well, and video streaming to be unreliable — but it is dramatically cheaper than shipboard Wi-Fi packages.
Performance
Land coverage and network tier
On land, GigSky rides top-tier partner networks across 190+ countries at 4G or 5G. Quality is good; the catalogue and pricing are simply less aggressive than the newer brands.
Installation is a standard QR or in-app flow, with plans available in both small trip sizes and longer regional buckets.
Pricing
Real plan pricing
| Destination | 1GB | 3GB | 5GB | 10GB |
|---|---|---|---|---|
| Europe (regional) | $6 | $14 | $20 | $35 |
| United States | $6 | $14 | $20 | $35 |
| Caribbean | $8 | $18 | $27 | $45 |
| Japan | $7 | $15 | $22 | $38 |

| Global | $10 | $25 | $38 | $65 |
Figures come from our own tracked pricing and move over time — treat them as a guide to the price band rather than a quote. Always confirm the current price on the provider's own checkout page before buying.

Choosing a plan
What size plan should you choose, and for how long?
| Plan type | Coverage | Best for |
|---|---|---|
| Cruise plan | At sea plus ports of call | Anyone sailing rather than flying |
| Fixed-data (local) | One country | Standard land trips |
| Regional | Europe, Asia, the Americas | Multi-country itineraries |
| Global | 190+ countries and territories | Long, wide-ranging trips |
GigSky is the rare case where the plan type matters more than the size. If any part of your trip is at sea, buy the cruise plan: a standard country plan stops working the moment the ship leaves coastal coverage, and onboard Wi-Fi is typically several times the price.
For land travel, the normal rules apply — a 3–5GB plan covers a week of maps and messaging, and regional plans usually beat two separate local plans as soon as you cross a border.
Cruise data is metered tightly, so treat it as a communications budget rather than a streaming budget: messaging, email and a daily check-in, with heavy downloads left for port.
Reputation
Trustpilot and user sentiment
Trustpilot hovers around 4.1. Cruise customers rate it highly; land-only customers are more mixed, mostly on price.
The most common complaint is that maritime data allowances disappear faster than expected — background app refresh at sea is the usual culprit.
GigSky's Trustpilot average is around 4.1, which sits mid-field, but the review pool is unusual: it mixes ordinary travellers with cruise passengers, and the two groups review very differently.
Cruise passengers are the enthusiasts. Their reviews repeatedly compare GigSky's price to what the cruise line charges for onboard Wi-Fi and conclude it is a fraction of the cost for a usable connection — several describe it as the single best purchase of the trip.
Land travellers are more lukewarm. For a normal city break GigSky is competent but not cheap, and reviews reflect that: the service works, the price is unremarkable, the app is functional rather than delightful.
The recurring complaint across both groups is data consumption at sea, where background app refresh and photo backup can burn a maritime allowance quickly. Turning off automatic backups before boarding prevents most of those bad reviews.
Setup
Setup and activation
- 1
Buy the right plan type first
Decide between a land plan and a cruise plan before anything else — they are not interchangeable, and only the cruise plan works at sea.
- 2
Install before boarding or flying
Install the profile at home over strong Wi-Fi. Onboard and airport connections are exactly where installations fail.
- 3
Scan the QR code in your phone's settings
iPhone: Settings > Cellular > Add eSIM. Android: Settings > Network & Internet > SIMs > Add eSIM.
- 4
Turn off backups and background refresh at sea
Before the ship leaves port, disable photo backup and background app refresh so your maritime data goes on messaging rather than uploads.
- 5
Enable data roaming
Switch on Data Roaming for the GigSky line so it can register on the local or maritime network.

Support
Customer service
Support is email and in-app ticketing rather than instant chat, which is the weakest part of the product and the reason a cruise plan should always be installed and tested before you sail.
Agents know the maritime side well — a genuine advantage, since most eSIM support teams have never handled an at-sea question — but response times are measured in hours, not minutes.
GigSky review: FAQs
Final word
The verdict
For a normal city trip GigSky is a competent, unremarkable choice at an unremarkable price. There is no strong reason to pick it over Maya, Nomad or Airalo.
For a cruise it is close to unique: ship and port connectivity in one purchase, on tier-one partner networks, at a fraction of what the cruise line charges. That is a genuine gap in the market and GigSky owns it.
Our recommendation: buy GigSky for the water, not for the land — and install and test it before you board.
