If you're deciding between Airalo and Saily for your next trip, this head-to-head comparison will save you half an hour of open tabs. We compare real price per gigabyte, coverage, app, activation, and support, and tell you when each is suitable and when to consider a third option before paying. Spoiler: there's no absolute winner, it depends on your destination.
Airalo vs Saily in a nutshell
Airalo is the most established eSIM with the most countries in its catalog; Saily is NordVPN's newer option, with a polished app and a focus on security. Airalo often wins in variety of exotic destinations; Saily, in app experience and regional plans. Both are low-cost, prepaid, with no contract.
The practical difference isn't in the logo, but in which country you visit and how much you value the app versus the raw price. Airalo has been on the market since 2019 and boasts coverage in over 200 destinations, while Saily arrived in 2024, leveraging Nord Security's infrastructure and brand. If you're traveling to an unusual country, Airalo's extensive catalog tends to have a plan; if you're going to Europe or the USA and want a clean interface with privacy extras, Saily plays that card very well. Neither ties you down: you pay for the plan, use it, and that's it.
Prices and plans head-to-head
In terms of price, both operate in the same low-cost league, but the breakdown changes depending on data and duration. Airalo offers great granularity (1 GB, 3 GB, 5 GB, 10 GB plans, and unlimited data plans in some countries), while Saily usually bundles slightly more generous data allowances with volume discounts. The key isn't the big number on the front page, but the real price per gigabyte for YOUR destination and YOUR travel dates.
| Criterion | Airalo | Saily |
|---|---|---|
| Model | Prepaid, no contract | Prepaid, no contract |
| Typical smallest plan | 1 GB / 7 days | 1 GB / 7 days |
| Unlimited plans | In selected countries | In selected countries |
| Volume discount | Yes, on higher tiers | Yes, marked on longer plans |
| Top-up | From the app | From the app |
Traveler's tip: don't buy the cheapest plan by default. First, calculate how much data you need for your trip based on the days and map usage, then compare the total amount, not the isolated price per GB.
Tip: If you're debating between 3 GB and 5 GB for a week, go for the larger plan. Running out of data at the airport on your way back causes more stress than the extra euro.
Coverage and network quality
Neither Airalo nor Saily have their own network: they resell local operators. This means that quality depends on the agreement with the operator in each country, not on the eSIM brand. In major destinations (Spain, Italy, USA, Japan), both perform well because they rely on main networks. The difference appears in niche or rural countries, where Airalo, due to its seniority and volume, usually has more agreements in place.
Another point is latency and tethering (sharing data via hotspot). Some reseller eSIMs limit or penalize router usage; it's advisable to check the specific plan details before buying if you plan to connect your laptop. For European trips, both rely on robust networks and the experience is very similar; if you're going to an exotic destination, check on each website that the country is listed with 4G/5G network and not just residual 3G. And remember: coverage on paper is not the same as real speed, which also depends on network congestion in the area.
App, activation, and experience
This is where Saily shines. Its app, inheriting NordVPN's design, is one of the cleanest in the industry: you buy, install, and see data consumption at a glance. Airalo also has its own app and website, functional but with more screens and some extra steps. Both allow eSIM installation via QR or directly from the app, and on compatible phones, the process takes around a couple of minutes.
If it's your first eSIM, the process is essentially identical: you scan a code or press a button, the profile downloads, and you activate data upon arrival. We've provided general guides on how to install an eSIM and how to activate it upon landing, which apply to any provider. An extra from Saily: it includes privacy features (malicious website blocking), something Airalo doesn't offer by default. If you travel a lot and like to keep everything organized in one interface, Saily's app wins for convenience.
Support and fine print
Support makes all the difference when something goes wrong 3,000 km from home. Airalo offers chat and a help center in several languages with a large community behind it; Saily relies on Nord Security's 24/7 chat support. In both cases, the primary channel is written (no phone), so response speed depends on the time and language.
The fine print to check for both: plan expiration (data expires even if you don't use it), top-up policy, whether the plan allows tethering, and what happens if you run out of data (it cuts off, no surprise overage charges, but you also can't browse). Neither includes a traditional phone number for calls: these are data plans, designed for calling via WhatsApp or other apps. If you need to receive SMS from your bank on your Spanish number, you'll have to use dual SIM mode, keeping your usual SIM active for messages.
Which to choose based on your trip
Quick summary to decide without further ado:
- Going to an unusual destination (Africa, Central Asia, islands): Airalo, due to its broader catalog.
- Traveling to Europe or the USA and value the app: Saily, for experience and privacy extras.
- Looking for the best total price: compare the final amount for your exact days; sometimes you save €2-3, other times not.
- Want Spanish support and clear plans: this is where local alternatives come in.
Before concluding, it's worth considering a third option. If your trip is European, also compare with our selection of the best eSIM for Europe in 2026 and the general ranking of the best eSIM for travel. You'll find options with Spanish support that sometimes offer a better price per gigabyte than the two international giants.
Practical tip: In Europe, many travelers end up paying less per gigabyte with specialized local providers than with a global plan from Airalo or Saily. It's worth comparing all three.
Frequently asked questions
Is Airalo or Saily better?
It depends on the destination. Airalo wins in variety of countries and exotic plans due to its seniority; Saily wins in app, convenience, and privacy extras for trips to Europe or the USA. In terms of price, they are very similar: compare the total amount for your specific days before deciding.
Do Airalo and Saily include calls?
Not by default. Both are data eSIMs: you browse, use maps, and make calls via WhatsApp, FaceTime, or Telegram. If you need a number for traditional calls or SMS, you'll have to keep your usual SIM in dual mode or look for a specific plan with voice, which is a minority in the eSIM market.
Is Saily from NordVPN?
Yes, Saily is the eSIM from Nord Security, the company behind NordVPN. That's why its app inherits the design and adds privacy features like malicious website blocking. Support also relies on Nord's 24/7 structure.
Can I use Airalo or Saily in multiple countries?
Yes. Both offer regional plans (Europe, Asia, America) and global plans, in addition to country-specific plans. If your trip covers several countries, a regional plan is usually more cost-effective than buying an eSIM for each destination. Check the list of covered countries before purchasing.
What happens if I run out of data?
In both, when you run out of gigabytes, you simply stop browsing; there are no surprise charges like with traditional roaming. To stay connected, you need to buy a top-up from the app. That's why it's advisable to choose a plan with some margin so you don't run out halfway through your trip.
Conclusion
Airalo and Saily are two reliable low-cost options: Airalo excels in rare destinations and catalog variety, Saily in app and convenience, and they are usually tied on price. The honest recommendation is to compare the total amount for your exact days and not commit to one brand. Before paying, also look at alternatives with Spanish support and choose the eSIM that best suits your destination and travel style.
