EsimCards for cruise passengers: reviewed
Short answer
EsimCards (esimcards.co.uk) is a UK travel eSIM retailer, run by Pentagram Systems Limited. It sells prepaid data eSIMs for more than 190 countries, plus separate UK carrier bundles. For a cruise, its travel plans work in the usual way. You buy data for your destination before you go, and it switches on at each port. There's no maritime option here.

Overview
EsimCards is a brand of Pentagram Systems Limited. It's a UK company registered in London. Pentagram also builds cloud, IoT, mobility and VoIP products alongside its eSIM business. Its Android app is published under the package name uk.co.esimcards. That ties the consumer brand straight back to the UK company.
EsimCards sells two different things. There are international travel eSIMs for more than 190 countries, built for tourists heading abroad. And there are UK carrier eSIM bundles from EE, Three, O2 and Vodafone. These suit people staying in the UK long-term. If you're going on a cruise, the travel eSIM line is the one you want. It's sold as instant-activation, prepaid data, not a monthly UK contract.
EsimCards holds a 4.2 out of 5 'Great' rating on Trustpilot. That's from 78 reviews, as of September 2026. Reviewers like the support team's quick replies, even in the middle of the night. A few say their eSIM stopped working before the trip was over. Others found a European plan didn't cover every country they expected.
Coverage on a cruise
EsimCards' travel eSIMs are standard land plans. They run on partner mobile networks in each destination. The company doesn't sell a maritime or offshore product. Like any land eSIM, the signal comes from a coastal phone tower. That reach runs out at about 12 nautical miles from shore. That's long before your ship is out of sight of land on a sea day. Buy an EsimCards plan for a cruise stop, and expect it to work only near land. It'll connect while you're docked, or while the ship is close to the coast. It'll go quiet again once the ship heads back out to sea toward the next port.
Plans and pricing
EsimCards' travel catalogue has some big bundles. One gives you 400GB of data across more than 30 European countries. Another gives you 100GB with voice and SMS across more than 50 countries (checked September 2026). Buying eSIMs together also saves money. A second eSIM costs 10% less, and a third or more costs 15% less. A promo code brings a further 5% off.
EsimCards also resells UK carrier plans. That shows the range Pentagram Systems runs under one brand. Examples include 100GB on EE for £15 a month and 40GB on Three for £24.50 a month. There's also 200GB on Vodafone for £22 a month. Multi-month terms save up to 10% more. There are student and gamer versions of these plans too. None of this matters for a cruise abroad, since these are UK-only bundles.

Setup and activation
Buying an EsimCards travel eSIM is simple. Pick a destination plan on the website, or on the dedicated Android app. It's published under the package name uk.co.esimcards. Pay, and a QR code arrives by email. Scan it to install the profile. You'll need an internet connection to do this. Set it up on home wi-fi before your cruise leaves.
There's also a physical SIM card option for phones that don't support eSIM. That route needs more lead time than the instant digital version. It's not practical to arrange once your cruise is already under way.

Regions EsimCards is ranked for
A port-day provider is listed for a region only where it genuinely fits the itinerary. Every region EsimCards holds a place in is below, with the reasoning for each.
| Region | Rank | Why |
|---|---|---|
| Southern Caribbean | #1 | Covers the ABC islands and the Windwards, which narrower packs often miss. |
| Caribbean | #3 | Covers smaller islands the big brands skip, useful on unusual itineraries. |
| Eastern Caribbean | #3 | Strong on the smaller Leeward and Windward islands. |
Cruise and ferry plans
The plans database on this site holds cruise, ferry and maritime products only. EsimCards publishes none, so there is no plan table on this page. Its regional data plans remain the relevant purchase for port days.
Verdict
EsimCards works well as a port-day data source for a cruise. It's run by a UK-registered company, with 24/7 support and handy multi-eSIM family pricing. The 4.2-star Trustpilot record is solid, if not outstanding. A few reports of early outages and unclear country coverage on European plans are worth noting. Before you leave, check that your chosen bundle lists every port country by name.

Frequently asked questions
01Does EsimCards work on a cruise ship?+
Docked, yes; underway, no. Nothing in the EsimCards range talks to a satellite or a ship-board base station, so the connection ends with the coastline and picks up again at the next quay.
02Does EsimCards sell UK mobile plans as well as travel eSIMs?+
Yes. Alongside its travel eSIMs, EsimCards resells carrier bundles from EE, Three, O2 and Vodafone for UK use. For a cruise abroad, you'd want the travel eSIM line. The UK carrier plans aren't for you here.
03Who operates EsimCards?+
EsimCards is a brand of Pentagram Systems Limited, a UK company registered in London. Pentagram also builds cloud, IoT and VoIP products. Its Android app is published under the package name uk.co.esimcards (checked September 2026).
04Are there discounts for buying more than one EsimCards eSIM?+
Yes. Buy a second eSIM and it costs 10% less. A third or more costs 15% less. That suits a family or group on the same cruise, where everyone needs their own data plan.
05Is there a refund if an EsimCards eSIM stops working?+
The site links to a refund and return policy. The pages reviewed didn't spell out the details, though (checked September 2026). Some Trustpilot reviewers describe eSIMs that stopped working early. It's worth confirming the refund process with support before you buy.
06Which cruise regions is EsimCards good for?+
