eSims: what are they & do you need one for your next cruise?
Cruise holidays are a chance to disconnect, but let’s face it, we all like the reassurance of having data when we need it. That’s where eSims come in. These digital alternatives to traditional SIM cards are becoming a popular, cost-effective way to stay connected when travelling. But are they worth it for a cruise?
eSims in a nutshell
eSims can be a smart, affordable way to access data and make calls while in port or sailing close to land. They won’t work in the middle of the ocean or connect to a ship’s onboard mobile network, but they’re handy for navigating, messaging or dealing with travel hiccups on land. A small bundle can cost as little as £4.
What are eSims?
An eSim (short for “embedded SIM”) is a virtual SIM card built into your phone. Instead of swapping out a plastic SIM when travelling, you can download an eSim profile and activate it instantly.
The cheapest eSims are usually data-only, letting you browse, message and use maps without racking up roaming charges. Some bundles also include voice calls and texts – handy if you’re travelling without Wi-Fi or need to call a local taxi or hotel.
How much do eSims cost?
Prices vary depending on how much data you need and whether you want calls and texts included. Data-only bundles covering multiple European countries start from around £4 for 1GB over seven days. For a package that includes data, calls and texts, expect to pay closer to £10–£15. Bundles for non-European destinations – like the Caribbean or the US – usually cost more. Most plans are pay-as-you-go and don’t require contracts or monthly fees.
What are the best companies for eSims?
There are a few big players in the eSim space offering international coverage and a wide range of plans. Popular options include:
Each has a slightly different offering – some focus on Europe, others on global coverage, and some allow top-ups while others don’t.
How to install an eSim on your smartphone
The process differs slightly depending on the make and model of your phone, but most eSim apps walk you through it step by step. You’ll usually scan a QR code or download a profile directly from the provider.
Here are the official guides for common phone brands:
Not all phones support eSims, so it’s worth checking before you buy.
Benefits of using an eSim on your cruise
- Cheaper than roaming: particularly useful on port days if your regular provider doesn’t include free roaming
- Peace of mind: you can access maps, local services or emergency contacts while exploring ashore
- Works near the coast: eSims often connect if your ship sails close enough to land
- Multi-country bundles: many plans cover several countries, so you won’t need to switch sims at every stop
Drawbacks of using an eSim on your cruise
- Limited coverage at sea: they won’t work once you’re out of range of land-based mobile networks
- No connection on the ship’s mobile network: you’ll need onboard Wi-Fi or your regular SIM (and risk roaming charges) for that
- Expiry dates: most bundles are time-limited (e.g. 1GB over seven days or 5GB over 30 days) and don’t roll over to your next trip
Things to consider before buying an eSim
- Is your phone compatible? Not all models support eSims
- Does your regular provider offer free roaming? You might not need an eSim if your plan already covers your destination
- Are you visiting multiple countries? Look for a bundle that includes all of them
- How many sea days are there? If you're crossing the Atlantic or spending most of your cruise at sea, you won’t get much use out of it
Should you buy an eSim for your next cruise?
An eSim can be a useful backup – especially if you’re sailing to destinations where your current provider charges extra for roaming. It gives you access to data and local services on port days without having to hunt for a coffee shop with free Wi-Fi.
Most providers allow you to download an eSim and activate it when needed, so you can keep it in your phone for up to 12 months before the data clock starts ticking. That means you can have one on hand just in case, without paying until you actually use it. For around £4–£12, it’s a low-cost way to stay connected and give yourself a bit of digital peace of mind while you’re off exploring.
