Airalo vs Saily vs Yesim: The Full eSIM Comparison
The three biggest travel eSIM providers, compared head-to-head for 2026 — pricing, coverage, app quality, and which one actually fits your trip.
The 30-second answer
- Best overall: Saily — cleanest app, competitive pricing from ~$3.99, built-in ad blocking + Virtual Location feature. Built by Nord Security (NordVPN).
- Best coverage / safest bet: Airalo — the original, 200+ countries, 300+ operators. The one most travellers already have installed.
- Best for heavy use / hotspot: Yesim — unlimited plans, strong tethering, best value at high data volumes.
- The honest truth: all three work well. The right one depends on your trip type, not which is “best.”
★ Best Overall
Saily
The easiest “just buy this” answer for most travellers. Cleanest app, sensible pricing, and a built-in VPN-style feature. Ideal for first-time eSIM users.
Widest Coverage
Airalo
The household name. 200+ countries, the biggest catalog, and the app you’ve probably already got from a previous trip. The reliable default.
Best for Heavy Use
Yesim
Unlimited plans and strong hotspot performance. The pick for digital nomads tethering a laptop or burning serious data on long stays.
Travel eSIMs have made the airport SIM-card queue obsolete. Buy a data plan in an app, install it before you fly, and you’ve got working mobile data the moment you land — no physical SIM, no roaming bills, no fumbling with a paperclip over a tiny tray. Three providers dominate the space in 2026: Airalo (the original and biggest), Saily (the Nord Security-built challenger), and Yesim (the heavy-data and hotspot specialist).
I’ve used all three across multiple trips. The honest headline: they’re all genuinely good, and the “best” one depends entirely on how you travel. This guide breaks down exactly who each one suits.

Saily — best overall for most travellers
Saily is the newest of the three, launched by Nord Security — the team behind NordVPN. In a short time it’s become the default recommendation for most travellers because it nails the two things that matter most: a genuinely clean app and sensible pricing. Setup is the smoothest of the three, which matters enormously if it’s your first time using an eSIM.
The standout differentiator is what’s bundled in: Saily includes ad blocking and a Virtual Location feature that works like a light VPN, letting you change your apparent location. For privacy-conscious travellers and anyone heading somewhere with content restrictions, that’s a real bonus no other eSIM bundles natively.
✓ Strengths
- Cleanest, most intuitive app — best for first-timers
- Competitive entry pricing (often from ~$3.99)
- Built-in ad blocking + Virtual Location (VPN-style)
- One reusable eSIM across multiple trips
- Nord Security backing = strong privacy credentials
- Reliable activation and top-up flow
✗ Trade-offs
- Slightly fewer countries than Airalo (150+ vs 200+)
- Newer, so less long-term track record
- Not always the absolute cheapest per-GB for tiny plans
- Fewer unlimited options than Yesim
Pick Saily if: you want the easiest possible setup, you value the privacy extras, or it’s your first eSIM and you just want something that works without fuss. For the majority of travellers, this is the right default.
Airalo — widest coverage, the safe choice
Airalo launched in 2019 as the world’s first eSIM marketplace and remains the biggest — over 10 million users, partnerships with 300+ mobile operators, and plans in 200+ countries and territories. If a destination has eSIM coverage at all, Airalo almost certainly offers it.
The case for Airalo is mostly about ecosystem and reach. If you’ve used it before — in Thailand, Japan, anywhere in Europe — you already know the app and trust the flow. Its regional plans (Eurolink for 39+ European countries, Asialink for Asia) are well-priced and well-presented, making it especially strong for multi-country trips. It’s the “nobody got fired for choosing Airalo” option.
✓ Strengths
- Widest coverage — 200+ countries, 300+ operators
- Most established and proven (since 2019)
- Excellent regional plans (Eurolink, Asialink)
- Huge user base = lots of reviews and community knowledge
- Many travellers already have the app installed
- Simple, reliable activation
✗ Trade-offs
- Entry pricing slightly higher than Saily (~$4.50)
- No built-in VPN/ad-block extras
- App is functional but less polished than Saily’s
- Limited unlimited-data options vs Yesim
Pick Airalo if: you visit lots of one-off countries, you want the broadest coverage, you’re doing a multi-country regional trip (Europe or Asia), or you simply want the most proven, widely-used option.
Yesim — best for heavy users and hotspot
Yesim covers 200+ countries with one purchase and leans into a different niche from the other two: heavy data use and tethering. Its unlimited plans and strong hotspot performance make it the standout for digital nomads working from cafés, anyone tethering a laptop, or travellers who burn through data fast.
The maths is simple: if you’re going to use 30GB in a week, Yesim’s unlimited plan will beat buying three 10GB top-ups on Airalo. For light users on 1-5GB it’s less compelling, but for the data-hungry it’s often the best value on paper. It also includes VPN-style routing, useful for working remotely or in restricted regions.
✓ Strengths
- Unlimited plans — best value at high data volumes
- Strongest hotspot/tethering performance
- 200+ countries on one reusable eSIM
- Built-in VPN-style routing
- Great for digital nomads and remote workers
- Good for unpredictable, frequent travel
✗ Trade-offs
- Higher entry price than Saily/Airalo for small plans
- “Unlimited” plans often have fair-use speed caps — read terms
- Less of a household name than Airalo
- Overkill for light, occasional users
Pick Yesim if: you’re a heavy data user, you tether a laptop or work remotely, you want one unlimited plan for a long trip, or you travel frequently and unpredictably and don’t want to keep buying fresh small plans. A note on “unlimited”: in the eSIM world, unlimited almost always means full-speed up to a threshold, then throttled — always check the fair-use terms for your destination.
Which should you actually pick?
Cut through the marketing — here’s the honest decision by traveller type:
| You are… | Pick | Why |
|---|---|---|
| First-time eSIM user | Saily | Cleanest setup, hardest to get wrong |
| Visiting one country, light use (1-5GB) | Saily or Airalo | Both cheap and simple; pick by app preference |
| Multi-country trip (Europe/Asia) | Airalo | Eurolink/Asialink regional plans are excellent value |
| Visiting an unusual / remote country | Airalo | Widest coverage — most likely to have it |
| Heavy data user / streaming | Yesim | Unlimited plans win at high volumes |
| Digital nomad tethering a laptop | Yesim | Strongest hotspot performance |
| Privacy-conscious / restricted region | Saily | Built-in ad block + Virtual Location feature |
| Already have Airalo from a past trip | Airalo | No reason to switch for a standard trip |
The simplest advice: If you’re not sure, get Saily for most trips. It’s the best balance of price, simplicity, and features for the average traveller. Switch to Airalo if your specific destination isn’t covered or you want a regional multi-country plan, and to Yesim if you know you’ll be a heavy data user. You genuinely can’t go badly wrong with any of them.
How to set up a travel eSIM (any provider)
The process is nearly identical across all three. The golden rule: buy and install before you fly, activate when you land.
- Check compatibility. You need an eSIM-capable, unlocked phone — iPhone XS or newer, Pixel 3 or newer, recent Samsung Galaxy S/flagship Android. Dial *#06# to check for an EID number, or look for “Add eSIM” in your settings.
- Buy the plan in the provider’s app while on home WiFi, choosing your destination and data amount.
- Install the eSIM profile — this downloads over WiFi (a QR code or in-app one-tap install). Do this before you leave home.
- Leave it switched off until you arrive, so it doesn’t start counting validity early (some plans start on install, others on first connection — check).
- On arrival, turn on the eSIM line for data and enable data roaming for that line. You’ll connect to a local network automatically.
- Keep your home SIM active for calls/texts if you want, with the eSIM handling data. Dual-SIM at its best.
Pro tip: whichever eSIM you choose, consider a separate VPN for sensitive tasks on public WiFi, and for any country with content restrictions (China especially — most VPN download sites are blocked once you’re inside, so install before you fly). Saily and Yesim include light VPN-style features, but a dedicated VPN is more robust if you really need it.
FAQ
Which is better — Airalo, Saily, or Yesim?
For most travellers, Saily is the best all-rounder — cleanest app, competitive pricing, and built-in privacy features. Airalo wins on coverage breadth and is ideal for multi-country or unusual destinations. Yesim is best for heavy data users and hotspot/tethering thanks to its unlimited plans. All three are reliable; the right one depends on your trip.
Is Saily cheaper than Airalo?
Saily’s entry plans often start lower (~$1.99-3.99 depending on destination) versus Airalo’s ~$4.50. But pricing varies by country and data amount — for small plans they’re usually close. For very heavy use, Yesim’s unlimited plans typically beat both. Always compare the actual price for your specific destination in each app.
Do these eSIMs work on my phone?
You need an eSIM-compatible, carrier-unlocked phone: iPhone XS and newer, Google Pixel 3 and newer, and most recent Samsung Galaxy flagships. Dial *#06# — if an EID number appears, you’re compatible. Older phones and some budget Android models don’t support eSIM.
Can one eSIM cover multiple countries?
Yes. All three offer regional and global plans. Airalo’s Eurolink (39+ European countries) and Asialink are particularly good value for multi-country trips. Saily and Yesim both offer regional plans and let you reuse one eSIM across destinations. For multi-country travel, a regional plan beats buying separate local plans.
Should I buy before or after I land?
Buy and install before you fly, on home WiFi. The profile downloads over WiFi; you just activate it on arrival. This gives you working data the second you land — no airport WiFi hunt, no SIM kiosk queue.
Does “unlimited” really mean unlimited?
Usually not literally. In the travel eSIM world, “unlimited” plans (most common on Yesim) typically offer full speed up to a daily or total threshold, then throttle to slower speeds. It’s still genuinely useful for heavy users, but read the fair-use terms for your specific destination before assuming truly uncapped data.
Will an eSIM give me a local phone number?
Generally no — travel eSIMs are data-only. You keep your home number on your physical SIM for calls and texts (which still incur roaming charges if used), while the eSIM handles cheap data. For calls, use WhatsApp, FaceTime, or similar over the eSIM data. A few providers offer add-on local numbers, but most travellers don’t need one.
