The prices, policies and ratings below come from each brand's own pages and Trustpilot, checked in October 2026.
Which is cheaper, Holafly or Saily?
Saily is much cheaper for light and moderate use: 1 GB for 7 days in the US costs $3.99 and 5 GB for 30 days in Japan $10.99. Holafly starts at $11.90 for 3 unlimited days in the US and charges $73.90 for 30 unlimited days in Japan (October 2026).
| Trip (prices Oct 2026) | Saily | Holafly |
|---|---|---|
| United States, short trip | 1 GB / 7 days: $3.99 | Unlimited / 3 days: $11.90 |
| United States, one month | 3 GB / 30 days: $8.99 | Unlimited, priced by the day |
| Japan, one month | 5 GB / 30 days: $10.99 | Unlimited / 30 days: $73.90 |
Saily also sells unlimited plans: in October 2026 its 15-day unlimited plan cost $45.99 in the US and $48.99 in Japan, so compare unlimited with unlimited if that is what you need.
How do Holafly and Saily unlimited plans differ?
Holafly never stops your data but may slow it under operator fair use for up to a day at a time, and it caps hotspot sharing at 1 GB per day. Saily unlimited plans give 3 or 5 GB per day at full speed depending on the destination, then up to 1 Mbps.
For heavy daily streaming, Holafly's model is simpler. Saily's unlimited plans are designed for normal phone use, and its terms prohibit excessive tethering beyond occasional personal use, so neither brand sells a laptop data plan.
Do you need an app for Saily or Holafly?
Saily installs its eSIM only through the Saily app, with no QR code option. Holafly can be bought on its website or app and installed from an emailed QR guide, so Holafly works without an app.
The Saily app adds an ad blocker, web protection and virtual location features, which privacy-minded travelers may value. If you prefer a QR code and no extra app, Holafly is easier.
Can you top up Holafly or Saily?
Saily lets you add data to the same eSIM in its app, with optional Auto Top-Up, and reuse that eSIM on future trips. Holafly trip eSIMs cannot be topped up; you buy a new Holafly eSIM for extra days or a new trip.
Which has better refunds, Holafly or Saily?
Holafly fully refunds an eSIM that was never activated within 6 months. Saily refunds in full within 30 days if the eSIM was not installed or activated, and after activation only if more than 99% of the data is unused.
Is Saily legit?
Yes. Saily is a prepaid eSIM service launched in 2024 by Nord Security, the company behind NordVPN, and operated by Saily UAB in Lithuania and Saily Inc. in the US. Saily rates 4.7 out of 5 from more than 32,100 Trustpilot reviews (October 2026).
Holafly is also well established: founded in Spain in 2017, it reported more than 15 million eSIMs sold by September 2025 and rates 4.7 out of 5 from more than 114,000 Trustpilot reviews.
Where does eSIM.site fit?
eSIM.site lists several fixed-data, unlimited and daily plans for each destination on one page, with no app needed and top-ups on most plans. It is data only, newer than Holafly and Saily, and only refunds an eSIM that cannot connect at all.
For a trip across several countries, the eSIM.site Travel Planner lets you pick every country on your itinerary and issues each eSIM on the day you need it, in one checkout. Before you buy any eSIM, check that your phone supports eSIM and is carrier-unlocked.

Our verdict
Saily is the better value pick for most short trips: its fixed plans cost a fraction of Holafly's, and you can top up the same eSIM. Holafly wins for travelers who want unlimited data without thinking about it and who might cancel, thanks to its 6-month refund window on unactivated eSIMs. If you do not want to install another app, Holafly or eSIM.site are easier than Saily.
