Best Travel eSIMs Compared: Airalo, Holafly, Nomad & Co

Read this first: who is writing this

FindeSIM sells travel eSIMs, so we have a stake in this comparison and you should read it with that in mind. We have tried to do the one thing that makes a comparison useful: describe how each provider actually works, say where it is genuinely the better choice, and give you a method for checking the numbers yourself.

We deliberately do not quote exact prices for competitors. Travel eSIM prices change weekly, differ by country and are often discounted, so any number printed here would be wrong by the time you read it. Instead we explain how each company structures its plans and show you how to compare them on equal terms. Always check the live price and the plan's terms on the provider's own page before you buy.

None of the providers below are affiliates of ours, and we do not earn anything if you choose them. The brand names belong to their respective owners.

What every travel eSIM has in common

Almost every consumer travel eSIM works the same way underneath. The provider does not own mobile towers in the country you are visiting. It buys wholesale data from one or more local mobile networks, packages it as a prepaid plan, and delivers it to your phone as a downloadable profile. When you switch the plan on abroad, your phone connects to a partner network in that country, exactly like roaming, only at a prepaid price and without touching your home plan.

That shared foundation is why the differences between providers are smaller than their marketing suggests. In the same country, two different travel eSIMs frequently connect to the very same local network. What changes is the commercial wrapper around it: how data is priced, how plans are bundled, how good the app and support are, and how clearly the limits are explained.

This is also why the cheapest plan on paper is not always the cheapest in practice. A plan that looks inexpensive but runs out in three days, or throttles you to a crawl after a vague fair-use threshold, costs you more than a slightly dearer plan that simply works.

• Your phone must be eSIM-compatible and carrier-unlocked. Check this before comparing anything else.
• Your home number stays active for calls and SMS on your main SIM, as long as you leave roaming off.
• Most travel eSIMs are data-only. If you need a local phone number for calls or verification codes, filter for that explicitly.
• Install over Wi-Fi before you leave, then switch the line on when you land.

The criteria that actually matter

Feature lists on provider websites are long and mostly identical. These are the criteria that change your experience on the ground, and the ones we use throughout this series of comparisons.

• Pricing model: fixed data bundles priced per plan, or unlimited data priced per day. This single choice decides which provider is cheaper for you.
• Real cost per day: the total price divided by the days you will actually use the plan, not the headline validity.
• Fair use and throttling: what happens after the heavy-use threshold on an unlimited plan, and at what speed.
• Hotspot and tethering: whether you can share the connection with a laptop or another phone.
• Network quality: which local networks the plan uses and whether 5G is included where it exists.
• Coverage breadth: single-country, regional and global plans, and how many destinations are covered.
• Top-ups and flexibility: whether you can add data to an active plan without installing a new eSIM.
• App and installation experience: QR code, direct install link, or a mandatory app.
• Support: how fast you can reach a human, and in which languages.
• Transparency: whether the limits, expiry rules and validity start are stated plainly before you pay.

Fixed data versus unlimited per day

Travel eSIM providers fall into two broad camps, and understanding the split saves more money than any promo code.

The first camp sells fixed data bundles: 1 GB, 3 GB, 5 GB, 10 GB and so on, each valid for a number of days. You pay for the amount of data, and the price per gigabyte falls as the bundle gets bigger. Airalo, Nomad and Saily are the best-known providers built around this model, and it is also how most wholesale-based stores, including ours, list their standard plans. It rewards people who know roughly how much data they use.

The second camp sells unlimited data priced per day of travel. Holafly built its brand on this approach. You choose a number of days and pay a daily rate that usually drops on longer durations, in exchange for not having to think about gigabytes. It rewards heavy users, people who stream, hotspot or work remotely, and anyone who hates the idea of running out of data in a taxi in an unfamiliar city. The trade-off is the fair-use policy that sits behind the word unlimited.

A useful rule of thumb: if you will realistically use less than around one gigabyte a day, fixed bundles almost always win. If you will use several gigabytes a day, or you simply value certainty, per-day unlimited can come out cheaper and calmer. Light users who buy unlimited are overpaying for peace of mind; heavy users who buy small bundles end up paying for several top-ups.

Airalo: the largest marketplace

Airalo describes itself as the first eSIM store and is the biggest name in the category. Its strength is breadth. It covers a very large number of destinations with local, regional and global plans, which makes it a sensible default for unusual itineraries where other providers have gaps.

Plans are fixed-data bundles with set validity periods. The app is polished, top-ups are available on many plans so you can extend an active eSIM, and there is a loyalty and credit scheme. Support is available through the app. Because it is so large, you will find reviews and troubleshooting threads for almost any country, which counts for something when you are debugging an install at an airport.

Where it is less compelling: it is not an unlimited-data specialist, so heavy users on a long trip may have to buy larger or repeated bundles. Cheap plans in popular destinations can be matched or beaten by smaller providers and wholesale resellers, so it pays to compare the specific country page rather than assume the biggest name is the cheapest.

• Best for: broad coverage, unusual destinations, regional and global plans, and travellers who want a well-known brand.
• Think twice if: you want true unlimited data, or you are chasing the lowest price in a single popular country.

Holafly: unlimited data, priced per day

Holafly is the unlimited-data specialist. Its plans are sold by the number of days rather than the number of gigabytes, which suits people who do not want to monitor usage. For long stays, video calls, constant social media and tethering a laptop, that simplicity is a real advantage.

The point to understand before buying is the fair-use policy that qualifies unlimited. Providers that sell unlimited data generally reserve the right to slow your connection after heavy use on a given day or across a plan, and some restrict hotspot sharing or exclude certain countries from the unlimited tier. The details differ by destination and change over time, so read the plan's terms on the country page, not just the headline.

Per-day pricing also means short trips can look expensive per day while long ones look better, so work out the total for your exact number of days rather than comparing rates.

• Best for: heavy data users, longer trips, people who want zero data anxiety.
• Think twice if: you only use maps and messaging, in which case a small fixed bundle will cost much less.

Nomad: fixed bundles, tidy plans

Nomad sits in the same fixed-data camp as Airalo, with a clean app, a clear list of data sizes and validity periods, and regional bundles for trips that span several countries. It is popular with budget-conscious travellers who like straightforward gigabyte-based pricing and the option to top up.

Its catalogue is smaller than Airalo's in the long tail of rare destinations, but for mainstream travel countries the coverage is broad. As with every provider, the right comparison is country by country: for one destination Nomad may be the cheapest, for the next it may not.

Plan terms matter here too. Check whether the plan is data-only, whether tethering is allowed and when the validity clock starts.

• Best for: mainstream destinations, travellers who prefer pay-per-gigabyte and top-ups.
• Think twice if: your itinerary includes small or remote destinations that you should verify are covered before you buy.

Saily and Ubigi: the other names you will see

Saily comes from the team behind NordVPN and is built around the same fixed-bundle model, with security features bundled into its app. If a private connection on public Wi-Fi matters to you, that is a genuine point in its favour, although you can get the same protection from any reputable VPN on any eSIM.

Ubigi, operated by the mobile infrastructure company Transatel, is closer to a telecom operator than a pure reseller, because it runs its own connectivity platform rather than simply repackaging someone else's. Travellers who care about the technical underpinnings and about reliability across many borders sometimes prefer it.

Both are worth checking for your specific country, especially for regional trips, where a bundle covering many countries can undercut buying several single-country plans.

Where FindeSIM fits

We are a storefront rather than a network: we source plans from a wholesale eSIM platform and put them on clear, country-by-country pages. The point is not to be the biggest, it is to be the easiest place to compare plans for one destination. Every country page lists the available plans side by side with data, validity, 5G support, tethering, throttling and the networks covered, in seven languages, so you can see the trade-offs before you pay.

You pay once by card, Apple Pay or Google Pay, with no subscription and no mandatory app, and your eSIM, QR code and install links appear in your dashboard straight away. We are a good fit if you know where you are going and want to compare plans on transparent terms. We are not the right fit if you want a company-run loyalty scheme or an unlimited-per-day product; in that case the providers above may suit you better.

Side by side at a glance

This summary describes each provider's general approach, not live prices or guarantees. Terms change, so treat it as a map and check the plan page before you buy.

• Airalo: fixed bundles, very broad coverage, local, regional and global plans, top-ups on many plans, app-led experience.
• Holafly: unlimited data sold per day, subject to fair-use terms, aimed at heavy and long-stay users.
• Nomad: fixed bundles with a tidy catalogue and regional options, strong on mainstream destinations.
• Saily: fixed bundles from the NordVPN team, with security tools in the app.
• Ubigi: operator-style connectivity platform with its own infrastructure, worth checking for multi-country trips.
• FindeSIM: side-by-side plan comparison per country, no subscription, no app required, seven languages.

How to choose in three minutes

Skip the brand loyalty and run this quick process. It takes less time than reading reviews and gets you a better answer.

• Estimate your data: light use (maps, messaging, email) is roughly 0.3 to 0.5 GB a day; moderate use (social media, some video) is 1 to 2 GB a day; heavy use (streaming, video calls, hotspot) is 3 GB or more a day.
• Multiply by your days, add a 20 percent buffer, and note the total gigabytes.
• Open two or three providers on the page for your destination and note the total price for that data and those days, not the headline rate.
• Check three terms: tethering allowed, throttling after a threshold, and when the validity period begins.
• If two options are within a dollar or two, choose the one with the clearer terms and the better support.
• Install the eSIM at home on Wi-Fi, keep your main line for calls, and switch on data roaming only for the eSIM line when you land.

Mistakes that cost travellers money

Most bad eSIM experiences come from a short list of avoidable errors rather than from any provider being unusually poor.

• Buying before checking that the phone is unlocked and eSIM-capable.
• Choosing a regional plan that does not actually include every country on the route.
• Treating unlimited as meaning no limits without reading the fair-use terms.
• Installing on airport Wi-Fi at the last minute instead of at home the night before.
• Leaving roaming on for the main SIM and getting billed by the home carrier anyway.
• Forgetting that a validity period usually starts on first connection or installation, depending on the plan, which affects when your days start counting.
