1 · The 60-second answer
You are flying into Europe for a week or two and you want data the minute you land. Holafly and Saily are the two names that keep coming up when the word "unlimited" is involved. Here is the short version.
Holafly sells days, never gigabytes. A Europe plan is unlimited data for as many days as you buy, on one eSIM that covers 33 countries. You pay for the comfort of never checking a meter.
Saily, the eSIM from the NordVPN people, sells both: cheap data buckets and an "unlimited" plan that is really 5 GB a day at full speed, then 1 Mbps. Cleaner app, slightly more countries, and a subscription tier if you travel all year.
The honest verdict. For a week, the two are within a dollar and a half of each other. Holafly wins if you tether a laptop or stream every night. Saily wins if you want the option of a cheap 3 or 5 GB bucket instead. A third option, Ringo Light, sells two weeks for $18.99, about ten dollars under either one's single week, and 30 days for $28.99, one payment each: unlimited data at full speed.
Prices were read on holafly.com, saily.com and ringoesim.com on 11 September 2026, Ringo Light prices updated 26 September 2026. All three quote in US dollars. All three change prices often, so treat the numbers as a snapshot.

All three are trip products you pay for once per trip. What separates them is the price for the length you need, and what unlimited means on each.
3 · The prices, side by side
Holafly's Europe ladder and Saily's are close enough that the choice is rarely about price. Here is the full picture for the trip lengths people actually book.

Read the Ringo Light column carefully. It sells two lines, each one payment with nothing that renews: 2 weeks at $18.99 and 30 days at $28.99. Both are unlimited data at full speed for the length of the plan.
For a week, Holafly and Saily land within a dollar and a half of each other, and Ringo Light's two weeks costs about ten dollars less than either one's week. Between the two in the title, the decision comes down to what "unlimited" means, not to price.
4 · What unlimited means on each
Nobody sells a plan with no ceiling. The word hides three different products.
- Holafly. The plan page states no daily cap on your own use. Sharing the connection is capped at 1 GB a day, and the terms carry a fair-use clause. In practice it behaves like unlimited for one person and one phone.
- Saily. Saily meters five gigabytes a day at full speed. After that the line drops to 1 Mbps until midnight. For maps, messaging and a video call that is plenty. For a laptop on a hotspot it is not.
- Ringo Light. Both plans are unlimited data at full speed with no daily cap, for the length of the plan.
If your week is heavy on streaming and tethering, Holafly is the safest buy. If you mostly use Wi-Fi at the hotel and data on the move, any of the three will do and the other rows in the table matter more.
5 · Holafly · where it wins and where it costs you
- Wins: the simplest product in the category. Pick days, pay, scan. There is no bucket to size and nothing to top up.
- Wins: one regional eSIM for 33 countries. Paris to Amsterdam to Berlin is one plan.
- Costs you: the premium for headroom. A 30-day plan is $73.90. If you use 8 GB in that month you paid for unlimited and used a bucket.
- Costs you: it ends when the days end. Extend the trip and you buy again. Come back at Christmas and you buy again.
6 · Saily · where it wins and where it costs you
- Wins: you can buy small. 1 GB for a week is $4.99 and 5 GB for a month is $19.49. Nobody in this comparison has a cheaper way in.
- Wins: the app. Checkout is quick, the plan list is readable, and the Nord account carries over if you already use NordVPN.
- Wins: a real subscription if you want one. Saily Ultra starts at $39.99 a month for 10 GB at full speed, then unlimited at 1 Mbps, in 121 destinations, and it comes with a phone number.
- Costs you: "unlimited" is 5 GB a day. Fine for most people, a surprise for the ones who bought the word.
- Costs you: the unlimited ladder is priced like Holafly's. $28.99 for a week and $71.99 for a month buys you no comfort that Holafly does not also sell.
7 · Where Ringo Light fits
Ringo Light is the data eSIM we sell today, data only, next to your own SIM. On the Europe plan it is honest about what it is.
- Two weeks cost $18.99, one payment. That is about ten dollars under a single week at Holafly or Saily. If a cheap week or two is all you want, Ringo Light is the cheaper buy and we say so.
- A month costs $28.99, one payment. Unlimited data at full speed with no daily cap, for the whole 30 days. Nothing renews.
- 37 countries, more than either rival, and the price never depends on where you are standing.
- Global for longer or wider trips. One plan for 133 countries, unlimited data at full speed, $49.99 a month, the only Ringo Light plan that renews.
Unlimited data at full speed for 2 weeks at $18.99 or 30 days at $28.99, one payment, no renewal.
