Plans and pricing approach
The core difference is unlimited-style destination plans (Holafly) versus fixed-data packages (Saily), so there is no universal cheaper option — value depends on how much data you use.
Holafly emphasizes unlimited-style data, subject to a fair-use policy, while Saily sells fixed-data packages in a single app. A heavy user may prefer Holafly's unlimited-style approach, while a light user may pay less with a small Saily package. If you want to see how these compare with a marketplace, read our Airalo vs Holafly comparison.
Saily also bundles built-in extras such as ad and tracker blocking, which can add value if you want a simple all-in-one app. For a single short trip a small Saily package is often the cheapest route, while a data-hungry traveler on one destination usually gets more peace of mind from Holafly's unlimited-style plan.
Coverage and trip types
Holafly covers 170+ destinations and Saily a broad range too, so both are wide — the figure that matters is whether your exact destination has a plan that fits.
Holafly is typically strongest for a single destination, while Saily's regional plans suit multi-country trips. For one country, our best eSIM for Spain guide can help, or browse eSIM destinations.
Both connect through local mobile networks, so real-world speed depends on the network and your location rather than the brand name. Confirm your exact destination is supported on either service, and for a multi-country route check that every country is included before choosing a regional Saily plan over separate local ones.
Data, hotspot, and longer trips
Holafly's unlimited-style plans reduce cap worry (fair-use applies), while Saily's fixed data lets you pay for what you need.
- Estimate daily use — streaming and tethering add up faster than maps and messaging.
- Holafly's unlimited plans often cap daily tethering; Saily adds no extra hotspot cap.
- For longer trips, Holafly offers longer destination plans; Saily offers larger packages.
Hotspot is the detail most likely to catch people out: if you plan to share your connection with a laptop, Saily's no-extra-cap approach is often more predictable than an unlimited Holafly plan with a daily tethering cap. For phone-only heavy use on one destination, Holafly's unlimited-style data is the easier pick.
Setup and app experience
Both are straightforward on a compatible, unlocked phone.
With Holafly you typically install before departure and activation is often automatic on arrival. Saily keeps purchase, installation, and usage tracking in a single app, which can feel simpler for a first eSIM. Install before you travel while you still have a reliable connection.
Confirm your phone is eSIM-compatible and carrier-unlocked before buying, and keep your home connection active until the travel eSIM is working. Installing ahead of time means you land connected instead of hunting for airport Wi-Fi to finish setup.
Refunds and support
Both offer refunds mainly before activation, with different details.
Holafly is often cited for a relatively generous overall refund window, with activated plans reviewed (sometimes with an administrative fee). Saily generally offers a full refund if the eSIM is not installed or the plan is not activated within its window. Neither refunds data you've already used, so only activate a plan when you're ready to rely on it.
For support, both are reached mainly through their app and help center. Since both protect refunds only before activation, decide on your plan and destination first and activate once you arrive, when you're ready to rely on the connection.
Pricing, data allowances, coverage, hotspot support, and refund terms vary by destination and plan, and change over time. Always confirm current details on the provider's website before purchasing.
Detailed comparison
Open a section for the specifics.
Holafly is known for destination plans that emphasize unlimited-style data (subject to a fair-use policy), with coverage across 170+ destinations plus regional and global options. Saily sells primarily fixed-data packages managed in a single app, with some unlimited options on certain destinations, across local, regional, and global tiers. Exact tiers, destination counts, and prices vary and change over time.
Holafly allows sharing on many plans, but its unlimited plans commonly apply a daily tethering cap, and the exact cap varies by plan. Saily states it does not add an extra hotspot cap beyond your plan's data, though some plans or devices may restrict it. If sharing your connection with a laptop matters, verify the current rule for the exact plan before buying.
Holafly is often cited for a relatively generous overall refund window, with full refunds generally available before activation and activated plans reviewed (sometimes with an administrative fee). Saily generally offers a full refund if the eSIM has not been installed or the plan has not been activated within its stated window; activated plans are not guaranteed. Read each provider's current refund page before buying.
On a modern, eSIM-compatible, carrier-unlocked phone, setup takes a few minutes for both. With Holafly you typically install before departure, and activation is often automatic when you arrive and enable data roaming. Saily is app-first: you buy and install the plan inside the Saily app. Install while you still have a reliable connection.
These themes come from public reviews, not our own testing. Holafly is praised for not running out of data on unlimited plans, with common criticism around hotspot/tethering daily limits and fair-use throttling. Saily is praised for its clean app, low entry price points, and built-in security extras, with occasional notes about enabling hotspot manually or setup steps.
For longer trips, match the plan to validity and total data. Holafly offers longer destination and monthly-style plans centered on unlimited-style data; Saily offers larger fixed-data packages with longer validity. Confirm the validity period covers your whole trip, and for multi-country travel compare a regional plan against separate single-country plans.
