What Is Gigsky?
If you have been searching for a Gigsky review before your next cruise or international trip, you are in the right place. I have gone through everything on gigsky.com so you do not have to, and I will give you the full picture, including the bits that are less flattering.
Gigsky is a US-based company called Gigsky, Inc., and it focuses on one thing: international mobile data for travellers. No calls, no SMS, just data. That is a deliberate choice, and in 2026 it is not really a limitation. WhatsApp, iMessage, and FaceTime all run over data anyway.
The company claims over one million users and coverage across roughly 200 destinations worldwide. That is a solid base for any travelling eSIM. But what really sets Gigsky apart is a positioning you will not find anywhere else: they describe themselves as "the only eSIM built for cruises".
On land, Gigsky is a competent data eSIM among several good options. At sea, it is in a category of its own. I will come back to that in detail, because it is the heart of this review.
How Gigsky Works as an eSIM
An eSIM is a digital SIM card built into your phone. There is no physical chip to swap, no trip to a foreign phone shop at the airport. You download a profile to your device, activate it when you arrive, and you are connected.
Gigsky works the same way. You pick your plan on the app or website, install the profile via a QR code or directly through the app, and activate it at the start of your trip. The profile stays on your phone and can be topped up any time without reinstalling. That reusable profile is one of the small details that makes repeat use genuinely convenient.
Gigsky Features Worth Knowing
What You Actually Get With a Gigsky Plan
Before getting into the cruise side of things, here is what every Gigsky plan includes regardless of destination:
- Data only (no native calls or SMS, by design)
- Hotspot and tethering allowed on all plans
- Reusable eSIM profile: top up without reinstalling
- App available on iOS and Android
- 24/7 customer support
- Currency selector on the website (including GBP)
- Free 100MB trial with no credit card required
The free trial is worth highlighting. You install the eSIM, use up to 100MB, and the plan simply stops when the data runs out. No hidden charge, no automatic renewal. It is a genuinely low-risk way to test whether Gigsky works on your device before committing to a paid plan.
Gigsky One, Rewards, and Extras
Beyond the standard plans, Gigsky offers a few extras that are relevant depending on how often you travel:
- Gigsky One: a subscription-style plan with generous data and global coverage, aimed at frequent travellers and digital nomads
- Gigsky Rewards: a points programme you accumulate across purchases
- Share and Save: refer a friend and you both get 25% off your next plan
- Gift cards: useful if you want to sort someone else's connectivity before a trip
- Inflight data: a newer offering that extends Gigsky's coverage to in-flight connectivity, so you can stay online from the airport lounge to the ship
The inflight option is still relatively new, but it fits neatly into the idea of seamless connectivity across every stage of a journey.
Gigsky Global Coverage
Around 200 Destinations on Land
Gigsky covers roughly 200 destinations for standard land-based travel. That includes most of Europe, North America, the Caribbean, the Middle East, Asia-Pacific, Africa, and Latin America.
Plans are structured in a few ways:
- Single-country plans: for one specific destination
- Regional plans: covering areas like Europe, North America, the Caribbean, or Asia-Pacific
- Global plans: for travellers moving across multiple regions
- Gigsky One: the subscription option for regular travellers
For a UK traveller heading to a single destination, a country or regional plan is usually the most cost-effective option. Gigsky One makes more sense if you travel several times a year and want one profile that handles everything.
Cruise Coverage: 290+ Ships Across Around 29 Lines
This is where Gigsky's coverage becomes genuinely impressive. The company covers more than 290 cruise ships across approximately 29 cruise lines. For a UK traveller, the relevant names include:
- P&O Cruises
- Fred. Olsen Cruise Lines
- Royal Caribbean
- Celebrity Cruises
- MSC Cruises
- Costa
- Disney Cruise Line
- Carnival
- Norwegian Cruise Line
- Princess Cruises
- Holland America
- AIDA
- TUI Cruises
- Virgin Voyages
- Oceania Cruises
- Silversea
- Seabourn
- Regent Seven Seas
- Azamara
- Windstar
- Explora Journeys
- Hapag-Lloyd
- Ritz-Carlton Yacht Collection
- And others including Aroya, Peace Boat, Cordelia, and Resorts World
If your cruise line is on that list, which it almost certainly is, you are covered. I have not come across any other eSIM provider with anything close to this level of cruise-specific coverage.

Gigsky Data Speed
What to Expect on Land
On land, Gigsky connects via local partner networks in each country. Speeds are generally 4G LTE where available, which is more than enough for maps, messaging, social media, and video calls.
The one speed-related limitation to know about: on unlimited plans, data speeds are reduced once you exceed 3.5GB in a single day. Full speed resumes the following day. For most travel use cases, 3.5GB per day is plenty. If you are planning to stream video continuously all day, you will hit that ceiling.
Data Speed at Sea
At sea, speeds depend on the maritime network available on your ship, and that connectivity is shared across the vessel. It is simply not the same as a strong 4G signal on land: the connection is functional for messaging, email, and light browsing, but you should not expect land-grade speeds in the middle of the ocean.
The more important point about speed at sea is timing. Gigsky states clearly on its website: "While on the ship, you must be 12 nautical miles offshore before your service will begin."
In practical terms, that means roughly one hour after leaving port before your Gigsky data kicks in at sea. This is not a fault or a bug. It is a technical constraint linked to how maritime networks operate. Know it in advance, and it will not catch you out.
Ease of Use
Setting Up Gigsky: Four Steps
Gigsky summarises the setup process in four steps, and it genuinely is that straightforward:
- Choose your destination: cruise zone, country, region, or global
- Install the eSIM: via the app or by scanning a QR code
- Activate when you travel: not before, to avoid wasting your allowance
- Top up any time: without reinstalling the profile
The app is available on both iOS and Android, and the Gigsky website is fully available in English with a GBP currency option. Support is available 24 hours a day, seven days a week.
Managing Your Plan Mid-Trip
One of the practical advantages of Gigsky is how easy it is to manage your data while travelling. You can check your remaining balance in the app, buy a top-up, or switch to a different plan without touching the eSIM profile itself.
If you run out of data mid-cruise, you do not need to find a Wi-Fi connection to reinstall anything. You top up through the app and carry on. That kind of frictionless experience matters when you are on a ship in the middle of the Mediterranean.
Cruise Ships Where Gigsky Works
How to Check Your Ship
Before you book a Gigsky plan for a cruise, it is worth verifying your specific ship on gigsky.com. The full list of covered vessels is available on the site, and you can search by cruise line or ship name.
The coverage list is updated regularly as new ships are added. Given that Gigsky already covers the vast majority of mainstream cruise lines sailing from UK ports, the chances of your ship being included are high. But it takes thirty seconds to check, and it is worth doing.
Cruise Ship Connectivity: What Gigsky Replaces
Most cruise ships offer their own Wi-Fi packages. These are typically sold per day, per device, and the pricing varies significantly between lines and cabin categories. The experience also varies: some ships have invested heavily in satellite internet infrastructure, others have not.
What Gigsky offers is an alternative to that ship Wi-Fi, using maritime data networks rather than the ship's own system. The key difference is that your Gigsky plan also covers you at port and on land during excursions, which ship Wi-Fi does not.
Is Gigsky Better Than a Cruise Ship's Wi-Fi Plan?
The Honest Comparison
I am not going to give you a specific price comparison, because ship Wi-Fi pricing varies too much between lines, routes, and booking times to make a single figure meaningful. What I can say is that cruise ship Wi-Fi is frequently priced at several tens of dollars per day, per device.
Gigsky's cruise plans start from around $5 per day, with Cruise + Land plans from $6.30 depending on the zone. For a seven or fourteen-night cruise, the potential saving is significant.
The other factor is coverage. Ship Wi-Fi stops being useful the moment you step ashore. Gigsky's Cruise + Land plan covers you on the ship, at the port, and on land during excursions, all on a single plan with automatic switching. That continuity is something ship Wi-Fi simply cannot match.
The Cruise + Land Plan Explained
The Cruise + Land plan is Gigsky's flagship product and the main reason to choose it over a generic data eSIM. Here is how it works across the three situations you encounter on a cruise:
| Situation | What Gigsky Does |
|---|---|
| At sea | Connects via the maritime network available on your ship |
| In port | Automatically switches to the local mobile network |
| On land | Connects to the mobile network of the country you are visiting |
The switching is automatic. You do not change profiles, reinstall anything, or manually select a network. Your phone connects to the strongest available signal. For a cruise with multiple ports of call across different countries, that seamless switching is genuinely useful.
Cruise + Land zones currently covered are: Asia, Middle East, Caribbean/USA/Mexico, and Europe.
Gigsky Troubleshooting and Customer Support
What to Do If Things Go Wrong
Gigsky offers 24/7 customer support, accessible through the app and website. Response times and quality of support are, as with any provider, variable according to user reviews. The most common issues reported by users relate to:
- The 12 nautical mile delay at sea: often flagged by users who were not aware of it in advance
- Device compatibility: occasionally an issue with older or carrier-locked phones
- Activation timing: activating too early before a trip and burning through data
The good news is that most of these are preventable with a bit of preparation. Read the setup instructions before you travel, check your device is unlocked, and activate your plan at the right moment.
Tips Before You Board
A few practical points that will save you frustration:
- Check your ship is on the covered list at gigsky.com before purchasing
- Do not activate your plan until you are ready to use it
- Expect roughly one hour without maritime data after leaving port
- Use the free 100MB trial to confirm the eSIM installs correctly on your device before your trip
Gigsky Device Compatibility
Supported Devices
Gigsky works on any eSIM-compatible device that is unlocked (not locked to a specific carrier). Compatible devices include:
- iPhone XS and later (including all iPhone 15 and 16 models)
- Samsung Galaxy S20 and later, plus selected A-series models
- Google Pixel 2 and later
- iPad Pro, iPad Air, and iPad mini (Wi-Fi + Cellular models)
If you are unsure whether your phone supports eSIM, go to Settings on an iPhone and look for "Mobile Data" or "Add eSIM". On Android, check Settings under "Network and Internet" or "Connections".
Gigsky With Older Phones That Do Not Have eSIM
If your phone does not support eSIM, Gigsky is not compatible. There is no physical SIM card option. In that case, you would need to look at providers that offer physical SIM cards, or consider whether upgrading your device before a cruise is worthwhile given the potential savings on ship Wi-Fi.
Most smartphones released from 2018 onwards support eSIM, so this is less of an issue than it was a few years ago. But it is worth confirming before you purchase a plan.
Gigsky for Tablets and Laptops
Gigsky works on compatible iPads (Wi-Fi + Cellular models with eSIM support). For laptops, eSIM compatibility is less common, though some newer Windows laptops and MacBooks with cellular connectivity may be compatible. Check your specific device model on gigsky.com before purchasing.
The hotspot feature means you can also share your phone's Gigsky data connection with a laptop or tablet that does not have its own eSIM. That is a practical workaround for most travellers.
Gigsky Pricing and Plans
What Plans Cost
Gigsky's pricing structure covers several categories:
- Land plans: from $3.99 for single-country options
- Cruise + Land plans: from $6.30 depending on zone, with some plans advertised from $5 per day
- Sea-Only plans: for connectivity on the ship without land coverage
- Regional plans: covering Europe, North America, the Caribbean, Asia-Pacific, and more
- Global plans: for multi-region travel
- Gigsky One: subscription model for frequent travellers
Prices are displayed in multiple currencies on the website, including GBP. You can select your preferred currency before checkout, which avoids any conversion surprises.
There are no public promo codes at the time of writing. The main ways to reduce the cost are the free 100MB trial (no card required) and the Share and Save referral programme, which gives both you and a friend 25% off.
Visa Card Benefits
If you hold an eligible Visa card, you may be able to unlock additional benefits through Gigsky's Visa partnership. These can include free data on selected destinations or discounts on plans. Eligibility depends on your specific card and issuing bank, so check on gigsky.com before your trip. If you are eligible, it is a meaningful bonus on top of an already competitive cruise offering.
Gigsky Reviews: What Other Travellers Say
App Store Rating and User Base
Gigsky holds a 4.6 out of 5 rating on the App Store, based on thousands of reviews, alongside a user base of over one million people. The recurring themes in positive reviews are the ease of installation, the reliability of the cruise connectivity, and the convenience of topping up without reinstalling.
For a service that operates in a technically complex environment (maritime networks, automatic switching between sea and land), a 4.6 App Store score is a strong signal that the product works as described for the majority of users.
Trustpilot: A More Measured Picture
In the spirit of an honest review, the Trustpilot score sits around 4.1 out of 5, which is more moderate than the App Store figure. The gap is worth acknowledging.
The most common criticisms on Trustpilot relate to the maritime data delay (users who were not aware of the 12 nautical mile rule) and occasional support response times. Neither of these is a fundamental product flaw, but they are worth knowing about.
« It genuinely works at sea, the connection is stable once you are out of port. The one thing to know is that you need to wait about an hour after leaving before the signal comes through. »
Trustpilot customer review
The overall picture from customer reviews is positive, particularly for cruise use. On land, some users note that cheaper alternatives exist for specific destinations, which is fair and worth factoring into your decision.
Gigsky Limitations
What to Keep in Mind
No provider is perfect, and Gigsky is no exception. Here are the limitations worth knowing before you buy:
- The 12 nautical mile rule: data at sea does not start until roughly one hour after leaving port. Plan accordingly.
- Speed throttling on unlimited plans: speeds drop after 3.5GB per day, resuming the next day.
- Data only: no native calls or SMS. You use WhatsApp, iMessage, or similar apps for communication.
- Land pricing: for a standard country trip with no cruise element, providers like Airalo or Saily may offer cheaper plans depending on your destination.
- No public promo code: the free trial and referral discount are the main ways to reduce cost.
- Messaging + Essentials plan: covers text-based messaging apps but explicitly excludes voice and video calls, as well as voice notes. If you need to make calls, you need a higher data plan.
Our Verdict: Who Should Use Gigsky?
The Ideal Gigsky User
Gigsky is the obvious choice if you are going on a cruise. No other eSIM provider comes close on ship coverage, and the Cruise + Land plan genuinely solves the connectivity problem that every cruise traveller faces. The free trial removes any risk from trying it.
It is also a strong option if you:
- Hold an eligible Visa card and want to benefit from the partnership
- Travel regularly and want a reusable eSIM profile without reinstalling
- Want to cover the full journey from airport to ship with Inflight data added
- Are travelling with family and want to share your connection via hotspot
When to Consider an Alternative
For a straightforward land-based trip to a single country, it is worth comparing Gigsky against other providers before committing. On land, the pricing is competitive but not always the cheapest option available.
If you need a local phone number for your destination, Gigsky is not the right tool. It is a data-only eSIM, and that is not going to change. For most travellers in 2026, that is not a problem. But if your trip requires a local number, look elsewhere.
