Airalo vs Holafly vs Saily (2026): The Honest Three-Way Comparison

Saily is generally the best balance of speed and price for travellers comfortable sizing their own data, while Holafly is superior for those who want unlimited data and refuse to think about gigabytes at all, and Airalo remains the safest default for obscure destinations thanks to the deepest catalogue in the market — though it is also the slowest of the three in most independent testing.

These are the three most-searched travel eSIM brands in the world, and they are genuinely different products rather than three versions of the same thing. Airalo is a marketplace optimised for breadth. Holafly is a single-product company that sells unlimited data by the day. Saily is a security company's entry into travel data, optimised for speed and app quality. Choosing badly between them is how travellers end up throttled on day three, or paying triple for data they never used.

Airalo Overview

Airalo is the largest travel eSIM marketplace by catalogue size, covering 200+ countries and regions. It is the brand most people encounter first, and it has the strongest name recognition in the category.

Reasons to choose Airalo:

• The deepest destination catalogue in the market — if a country sells travel eSIMs at all, Airalo almost certainly lists it
• Low entry prices, commonly from around USD 4.50 for 1 GB over 7 days
• Mature, stable app with straightforward top-ups and a usable regional and global plan range
• Long operating history and a large installed base, which means plenty of independent reviews to check before buying
• Loyalty credits on repeat purchases, which add up for frequent travellers

Reasons to avoid Airalo:

• Independent speed testing repeatedly places Airalo in the lower half of the field, often in the 10–22 Mbps range
• Its unlimited plans throttle at roughly 3 GB, which is low for a plan sold as unlimited
• Support is ticket-based; responses are competent but rarely immediate, and there is no true 24/7 live human channel
• Plans expire on a fixed schedule and unused data is lost

Holafly Overview

Holafly built its entire business on unlimited data plans sold by duration rather than by volume. It covers roughly 160+ destinations and is the most aggressively marketed brand of the three.

Reasons to choose Holafly:

• Unlimited data on essentially every plan — you choose days, never gigabytes
• 24/7 live chat with genuinely fast first-response times, the best support channel of the three
• Removes the single most common travel data anxiety: running out mid-trip
• Simple purchase flow with no volume maths required
• Strong presence and Spanish-language support, which matters for Latin American travellers

Reasons to avoid Holafly:

• By some distance the most expensive of the three on a per-day basis
• Carrier fair-use policies throttle heavy users, in practice around 3–5 GB per day, after which speeds fall sharply
• Independent testing has recorded pre-throttle speeds around 7 Mbps and sub-1 Mbps once throttled — the weakest raw performance in this group
• Hotspot and tethering are restricted or disabled on several unlimited plans, which is a serious limitation if you travel with a laptop
• Smaller destination catalogue than Airalo

Saily Overview

Saily is built by Nord Security, the company behind NordVPN. It covers roughly 150 to 190 destinations and sells metered data only, with security tooling bundled into the app.

Reasons to choose Saily:

• Tested speeds commonly in the 25–40 Mbps band across the EU and Asia, clearly ahead of Airalo and Holafly
• Competitive entry pricing, often from around USD 3.99 for 1 GB over 7 days
• Ad blocking, web protection and virtual location features included in the app at no extra cost
• Clean, modern app and transparent pricing with no throttling games — a metered gigabyte is a full-speed gigabyte
• Backed by an established security company rather than a travel startup

Reasons to avoid Saily:

• No unlimited plans at all, so you must forecast your own usage
• Smaller catalogue than Airalo, with gaps in less-travelled destinations
• Longer-duration plans in some countries climb quickly in price
• Newer brand with a shorter track record than Airalo

Coverage

Airalo wins this outright. With 200+ countries and regions it is the only one of the three you can rely on for a genuinely obscure destination without checking first. Holafly covers around 160 destinations, which is enough for essentially every mainstream holiday but thins out in Central Asia, parts of Africa and smaller island nations. Saily sits in a similar band to Holafly, with its own gaps.

For the overwhelming majority of trips this does not decide anything — all three cover Japan, Spain, Thailand, Mexico and the United States perfectly well. It only matters if you are heading somewhere unusual, or if you want a single brand to handle every trip for the next few years.

Pricing and value

Saily and Airalo are both cheap on paper, with entry plans in the USD 4–5 range for 1 GB over a week. Saily generally edges Airalo on effective value because you get meaningfully faster data for similar money, and Airalo's loyalty credits only partly close that gap.

Holafly is a different pricing model entirely and should be judged differently. Paying roughly USD 6 or more per day is poor value if you use 500 MB a day, and good value if you genuinely consume several gigabytes daily. The problem is that Holafly's fair-use throttling tends to bite at around 3–5 GB per day, which is close to the level at which the plan starts justifying its price. That is an uncomfortable overlap: the users for whom Holafly is economically sensible are the same users most likely to hit the throttle.

The honest summary: for light and moderate users, Saily is the best value of the three. For heavy users, Holafly is the right model but a flawed execution. Airalo is rarely the best value on either axis — you buy it for coverage, not for price or performance.

Unlimited data

Only Holafly sells unlimited as its core product, and this is the main reason people shortlist it. Airalo offers unlimited on some plans but throttles at roughly 3 GB, which is low enough that many travellers never experience it as unlimited at all. Saily does not offer unlimited in any form.

Anyone shopping specifically for unlimited should understand two things. First, "unlimited" in this industry almost always means unlimited at reduced speed after a daily fair-use threshold, not unlimited at full speed. Second — and this catches more people out — unlimited does not imply hotspot. Holafly restricts or disables tethering on several unlimited plans, so if you intend to connect a laptop or share with a travel companion, you must check the specific plan before purchase.

It is worth noting that unlimited plans with hotspot permitted do exist elsewhere in the market: HOLASIM, for example, sells unlimited plans that allow tethering and runs a profile that does not expire between trips. If unlimited plus hotspot is your actual requirement, it is worth looking beyond these three.

Support and user experience

Holafly is the clear winner on support. Its 24/7 live chat genuinely answers quickly, and for a traveller stranded without data at an airport that is worth real money. Its app is simple because the product is simple: pick a country, pick days, done.

Saily has the best app of the three. It is modern, clearly laid out, and the bundled ad blocking and web protection are a genuine extra rather than marketing dressing. Support is a mix of chat and ticketing and is adequate rather than outstanding.

Airalo's app is the most mature and the most stable, which counts for something, but its support is the weakest of the three in practice: ticket-based, competent, and slow enough to be frustrating in an actual emergency. With the largest user base in the category, Airalo also carries the largest volume of public complaints — some proportional to its size, some not.

Which should you choose?

• Backpacker: Saily. Low entry price, the fastest data of the three, and you have the time and flexibility to top up when you run low. The bundled security tools are a real benefit on public Wi-Fi.
• Business traveller: Holafly if you need certainty and tether nothing; Saily if you need speed and will manage your own volume. If you must tether a laptop on an unlimited plan, neither is ideal — look at providers that permit hotspot on unlimited, such as HOLASIM.
• Family holiday: Holafly, with the hotspot caveat checked first. One unlimited plan is simpler than rationing four metered ones — but confirm sharing is permitted on the exact plan you buy.
• Digital nomad: Saily for day-to-day work, on speed and price. Airalo as a backup for the occasional destination Saily does not cover.
• Travelling somewhere unusual: Airalo. It is the only one of the three likely to have a plan at all, and a slow connection beats none.

FAQ

Which is cheapest?

Saily, in most markets, with entry plans commonly from around USD 3.99. Airalo is close behind and sometimes cheaper on specific destinations. Holafly is the most expensive by a wide margin on a per-day basis.

Which is fastest?

Saily, clearly, with tested speeds commonly in the 25–40 Mbps range. Airalo typically lands at 10–22 Mbps. Holafly records the slowest figures of the three, around 7 Mbps before throttling and under 1 Mbps after.

Is Holafly's unlimited data really unlimited?

Not at full speed. Carrier fair-use policies throttle heavy users, in practice around 3–5 GB per day, after which speeds drop sharply. It is unlimited in the sense that you will not be cut off, not in the sense that speed is constant.

Can I use these as a hotspot?

Airalo and Saily permit tethering on their standard plans. Holafly restricts or disables it on several unlimited plans, so check the specific plan page before buying if you need to share your connection.

Which has the best support?

Holafly, by a clear margin, thanks to 24/7 live chat with fast first responses. Saily is adequate. Airalo's ticket-based support is the weakest of the three when you need an answer immediately.

Do any of them keep working between trips?

No — all three sell plans that expire on a fixed schedule, and unused data is lost. If you want a profile that stays installed and is simply topped up for the next trip, you need a provider built that way, such as HOLASIM.

The verdict

If you can estimate your own data use, Saily is the best of these three: fastest, cheapest at entry, best app, and no throttling games. If you cannot or will not estimate, Holafly removes that decision entirely, and its 24/7 live chat is the best support in the category — but you pay a premium, you may be throttled exactly when you need the data most, and tethering may not be available to you. Airalo is the coverage insurance policy: not the fastest, not the cheapest in real terms, but the one most likely to have a plan for wherever you are going. And if what you actually want is unlimited data with hotspot permitted and a profile that survives to your next trip, none of these three delivers all of it, which is worth knowing before you buy.
