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 structural, not marketing. Airalo sells you gigabytes, a fixed data package for a country or region, while Holafly sells you days of unlimited data. Once you know whether you want to ration your data or forget it exists, the choice gets a lot simpler.
Side by side
| Airalo | Holafly | |
|---|---|---|
| What it really is | A pay-per-data eSIM marketplace. You buy a fixed chunk of data (say 1, 3, 5, 10, 20 GB) that lasts for a set validity window, in one country or a region. | 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 | Priced by gigabytes plus validity. You pay for what you think you will use, so light and predictable trips come out ahead. | Priced by days of unlimited data. You pay for a stretch of time, not a quota, so heavy or unpredictable use comes out ahead. |
| Country & regional catalogue | Very broad. Local plans in 200+ countries and territories, plus regional bundles and a global "Discover" plan. | Wide, but smaller. 160+ destinations plus regional bundles, with fewer of the obscure single-country options you find on Airalo. |
| Data allowance | Capped. When the GB run out you top up or buy a new package. No surprise overage charges, but you do have to keep an eye on the meter. | Unlimited on most plans, within a fair-use policy that can slow your speeds once you cross a high daily-usage threshold. |
| Keep your number / calls | Data-only on most plans, though a few destinations add a local number or credit. There is no native voice on the data eSIM itself. | Data-first, but certain plans throw in a phone number or WhatsApp / keep-your-number features in select destinations. |
| Hotspot / tethering | Usually fine. You are spending your own capped data, so sharing it with a laptop is straightforward. | Limited or switched off on some unlimited plans to protect fair use, so check the plan terms before you rely on it. |
| Loyalty / rewards | Airmoney-style loyalty credit on your purchases, which you can put toward 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. Holafly's unlimited plans come with a fair-use policy and tethering limits, and Airalo packages expire at the end of their validity window even if you have data left. Check that your device supports eSIM 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 is usually happier on a Holafly unlimited plan, within its fair-use terms. The right answer is whichever matches how much data your trip will really move.
Decide it with your own trip

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. The honest test is your daily gigabyte habit. Low and predictable leans Airalo; high or all over the place leans Holafly.
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 some limit hotspot or tethering so one plan does not end up powering a whole fleet of devices. For normal heavy phone use, this rarely bites. If your plan is to ditch home broadband and tether a laptop all day, read that plan's fair-use and tethering terms first instead of assuming truly 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-first rather than full voice plans, so for everyday calls you lean on WhatsApp, FaceTime or the like over the eSIM's data. A few Holafly destinations and select Airalo plans do add a local number, but do not count on native voice from the travel eSIM.
