Comparison

Airalo vs Holafly: data, coverage and which eSIM to pick

Published:

Both names top every "best travel eSIM" list, and the right answer is almost never the same for any two travellers. The difference is one of default, not marketing. Airalo leads with gigabytes, a fixed data package for a country or region, while Holafly leads with days of unlimited data. Airalo now sells unlimited day plans too, so the two overlap more than they used to, and the useful question has shifted: not who offers unlimited, but who tells you where "unlimited" stops.

Side by side

Airalo Holafly
What it really is An eSIM marketplace selling two shapes of plan: a fixed chunk of data (say 1, 3, 5, 10, 20 GB) on a set validity window, and, in 130+ countries, day-based unlimited plans. Sold per country, per region or worldwide. An unlimited-data eSIM brand. You buy a number of days and, on most plans, use as much data as you like, sold per country or per region.
Pricing model Two ways. Gigabytes plus a validity window on the data packages, or a flat day rate on the unlimited ones. Light and predictable trips still come out ahead on the GB packages. Priced by days of unlimited data. You pay for a stretch of time, not a quota, so heavy or unpredictable use comes out ahead (Japan: $11.90 for 3 days, $73.90 for 30).
Country & regional catalogue Very broad. Local plans in 200+ countries and regions, plus regional bundles and a worldwide global plan. Wide, but smaller. 160+ destinations plus regional bundles, with fewer of the obscure single-country options you find on Airalo.
Data allowance Both kinds. Capped GB packages you top up when they run dry, and unlimited plans in 130+ countries that run full speed to 3 GB a day, then continue at reduced speed. No overage charges either way. Unlimited on the travel plans, within a fair-use policy. Holafly publishes no daily gigabyte figure, so unlike Airalo there is no stated number to plan against.
Keep your number / calls Data-only on most packages, but the store also lists Data / Calls / Texts packages on some destinations, a few with a US number. No native voice on a data-only eSIM. Travel eSIMs are data-only in most countries (Japan included). The monthly Unlimited Plan adds a US, UK or Canada number, but it takes inbound SMS only and calls run over VoIP.
Hotspot / tethering Allowed, and stated plainly: Airalo says its unlimited eSIMs support tethering to laptops, tablets and travel companions, with no separate sharing cap. Allowed but metered: every travel eSIM shares up to 1 GB a day, and only the monthly Unlimited Plan lifts that to unlimited sharing.
Loyalty / rewards Airmoney cashback on purchases and top-ups, tiered from 5% at entry level to 10% once you have spent $200, spendable on future packages. The odd promo code or discount, rather than a standing points programme.
Best-known strength The cheapest way to get just-enough data almost anywhere, with the widest destination list around. Stop counting gigabytes. Unlimited day plans built for streaming, video calls and heavy hotspot use.

Both providers shuffle their pricing and plan rules often, and the exact data caps, "unlimited" fair-use limits, tethering rules and destination lists shift from country to country. Treat everything above as an estimate, and confirm the current details on Airalo's and Holafly's own stores before you buy.

Which to pick, and when

Eligible Pick Airalo if your usage is light to moderate (maps, messaging, a bit of browsing) or you are headed somewhere off the beaten track. You get the widest catalogue and pay only for the gigabytes you actually need.

Eligible Pick Holafly if you stream, take long video calls, or tether often and would rather not babysit a data meter. Paying for unlimited days takes away the dread of running dry at the worst possible moment.

Note Match it to the trip, not the brand. A short city break and a month of remote work can happily run on different providers. The "right" eSIM is just the one that fits this trip's data shape.

Depends Mind the edges. Every unlimited plan on both sides carries a fair-use policy, and hotspot sharing is metered separately from the headline data. Airalo packages expire at the end of their validity window even if you have data left, and both are data-only unless you specifically buy a plan with a number. Check that your device supports eSIM and is carrier-unlocked before you pay.

The one distinction that decides it

Strip away the marketing and it comes down to one question: do you want to ration data or stop thinking about it? Airalo is built for buying exactly enough data at the lowest price across the widest set of countries, which suits you when your usage is predictable or you are headed somewhere obscure. Holafly is built for never counting gigabytes, which suits you when you stream, hotspot, or just refuse to watch a meter on holiday.

Neither one is "the winner" in the abstract. A weekend traveller checking maps and posting a few photos is usually best served by a small Airalo package. A remote worker on video calls who tethers a laptop wants an unlimited plan, and both providers sell one, so the tie-breaker there is the fine print rather than the brand: which plan states its daily speed threshold, and which states how much of it you may share with a laptop. The right answer is whichever matches how much data your trip will really move.

Decide it with your own trip

Instead of trusting a generic ranking, match a plan to your actual destination, trip length and data habits:

Frequently asked questions

Is Airalo or Holafly cheaper? +

Neither one wins on price across the board. It comes down to how much data you actually use. Airalo sells fixed amounts of data, so if you mostly check maps, send messages and browse now and then, a small Airalo package tends to be the cheaper pick, and you just top up if you run dry. Holafly sells unlimited data by the day, so if you stream, sit on long video calls or tether a laptop all day, paying for a stretch of time instead of a quota can beat buying bigger and bigger Airalo packages. Worth knowing: Airalo now sells day-priced unlimited plans of its own in a long list of countries, so on a heavy-use trip you should price both unlimited options rather than assuming only one exists. The honest test is still your daily gigabyte habit. Low and predictable leans toward a capped package; high or all over the place leans toward buying days.

Does Holafly's "unlimited" really mean unlimited? +

In practice, "unlimited" comes with a fair-use policy. You will not hit a hard gigabyte wall, but most unlimited eSIMs, Holafly included, keep the right to slow your speeds once you pass a high daily-usage threshold, and hotspot sharing is metered separately from the headline allowance. The difference worth noticing is disclosure: Airalo publishes the daily figure at which its unlimited plans slow down, while Holafly does not, so with Holafly you are trusting a policy rather than planning against a number. Holafly is the clearer of the two on hotspot, where it states a daily sharing allowance outright. Both sets of figures are in the table above. For normal heavy phone use none of this bites. If your plan is to ditch home broadband and tether a laptop all day, read the fair-use and sharing terms first instead of assuming endless full-speed data.

Can I keep my normal phone number while using either eSIM? +

Yes. Both are built to run alongside your existing SIM or eSIM. You install the travel eSIM as a second line for data and leave your home SIM active, usually with its mobile data switched off to dodge roaming charges, so calls and texts still land on your usual number. Most Airalo and Holafly plans are data-only rather than full voice plans, so for everyday calls you lean on WhatsApp, FaceTime or the like over the eSIM's data. Airalo lists separate Data / Calls / Texts packages on some destinations, and Holafly's monthly subscription tier comes with a number, though it receives texts only and routes calls over the internet. Neither is a substitute for a local SIM if you need a real number for bank codes.
