"Unlimited" is doing a lot of work in travel-eSIM marketing right now, and most of it is vague on purpose. Airalo's Unlimited data eSIM plans are one of the few in the category that actually publish their fair-use numbers up front instead of hiding behind the word "unlimited" — here's exactly what that means, how it stacks up against other unlimited eSIM providers, and how to get one set up before your trip.
In a Nutshell
The short version
- What "unlimited" means: 3GB/day at high speed (up to 20 Mbps), then throttled to roughly 1 Mbps for the rest of that day. Resets daily.
- Coverage: Unlimited plans are available for 121+ single destinations (3, 5, 7, 10, 15, or 30-day options), plus regional bundles covering Europe, LATAM, Africa, the Caribbean, Oceania, and EU+UK.
- Setup: Install over WiFi before you fly, activate the data plan the moment you land — no physical SIM, no store visit.
- Catch: You need an unlocked, eSIM-compatible phone. Check before you buy.

What Is Airalo's Unlimited eSIM, Exactly?
An eSIM is a digital SIM card — no physical chip to swap, no tray to pop open. You buy a data plan for wherever you're headed, install it onto your phone before you travel, and it sits there ready to activate the moment you land. Airalo's Unlimited eSIM line applies this to "unlimited" data specifically: instead of a fixed data cap you buy in advance and hope covers your trip, an Unlimited plan gives you a high-speed daily allowance that resets every day for the length of your plan.
It's available as a single-destination plan (3, 5, 7, 10, 15, or 30 days) for 121+ countries, or as a regional bundle if your trip spans borders — Europe, the EU+UK, LATAM, Africa, the Caribbean, and Oceania all have their own multi-country Unlimited options.
The Fair Use Policy — Why the Transparency Actually Matters
Almost every "unlimited" data plan in travel, whether it's an eSIM or a phone carrier's own international add-on, is subject to some kind of fair use policy: once you cross a certain amount of data in a day, your speed drops. The difference is whether the provider tells you the actual numbers or just says "fair use applies" and leaves you guessing.
Airalo publishes theirs plainly: 3GB per day at up to 20 Mbps, then throttled to roughly 1 Mbps for the remainder of that day, resetting at the start of the next. 3GB/day comfortably covers maps, messaging, browsing, and a reasonable amount of photo/video sharing with room to spare — and even after you hit it, throttled speed still handles maps and messaging fine; it's heavier things like video calls and media-heavy feeds that slow down.
How It Compares to Other Unlimited eSIM Providers
Every "unlimited" travel eSIM has a fair-use cap somewhere — the real differences are in what that cap actually is, and whether the provider tells you upfront. Based on each provider's own published terms:
| Provider | Daily High-Speed Cap | Speed After Cap | States the Cap Upfront? |
|---|---|---|---|
| Airalo | 3GB/day (20 Mbps cap) | ~1 Mbps | Yes |
| Saily | 5GB/day (no speed limit within it) | ~1 Mbps | Yes |
| Jetpac | 2–5GB/day (plan dependent) | ~1 Mbps | Yes |
| Nomad | 2–3GB/day (plan dependent) | ~1 Mbps | Yes |
| Holafly | Not disclosed (fair use policy applies) | Varies by carrier | No |
Figures reflect each provider's own published terms as of September 2026 — check the provider's current terms directly, since plans and caps change.
Hotspot/tethering is allowed on Airalo's plans wherever your device and the local network support it, and manual top-ups are available in most destinations if you do run through a plan before your trip ends.
Setting Up an Airalo eSIM
The process is the same whether you're getting a single-destination or regional Unlimited plan:
- Download the Airalo app (or use their website) and choose your destination.
- Pick your plan — for Unlimited, that means choosing your trip length (3 to 30 days).
- Install the eSIM over WiFi before you travel — it takes a few minutes, and you can do this any time before your flight.
- Activate it when you land. Your data plan turns on the moment you touch down, without using any of it beforehand.
Before you buy anything, confirm your phone is both unlocked and eSIM-compatible — most iPhones from the XS onward, most Google Pixel phones from the 3 onward, and many recent Samsung Galaxy models qualify, but a locked or older device may not. Check under Settings → Cellular/Mobile Network for an "Add eSIM" option, or see our own eSIM compatibility rundown.
"You keep your home number on your physical SIM for calls — the eSIM only handles data."
Most phones support dual SIM, meaning the eSIM runs alongside your existing physical SIM rather than replacing it — your home number stays active for calls and texts the whole trip.
Airalo eSIM vs. Roaming vs. a Local SIM Card
The honest comparison, without picking a side you don't need picked:
- vs. carrier roaming: An eSIM is prepaid with a fixed cost you know upfront — no surprise bill when you get home. Most carrier day-rates for international roaming cost more per day than a comparable eSIM plan.
- vs. a local SIM card: No store visit, no ID paperwork, no language barrier at a counter — you install it before you even leave home and it's just... on when you land. The tradeoff is a local SIM sometimes undercuts an eSIM on pure price if you're staying somewhere a long time.
- vs. public WiFi: Public networks are often unencrypted; a cellular data connection through your own eSIM is private by comparison.
