Search for a travel eSIM and “unlimited data” is everywhere — Holafly and Yesim are the best-known names selling it for Europe. We did something boring: we read their fair use policies. The result, from their own help centers (as of July 2026): every “unlimited” eSIM we checked has a documented daily limit. Policies change, so always check the current terms before you buy — but here is what they say today.
Holafly: unlimited, with daily speed management and a hotspot cap
Holafly’s own FAQ explains that a fair usage policy can reduce your speed after a daily allowance — reports and reviews put the threshold around 2–3 GB per day in many destinations (some up to 5 GB), with normal speed returning the next day. On top of that, the Europe plans cap hotspot/tethering at roughly 500 MB per day. So the phone may keep browsing, but sharing data with a laptop or TV hits a wall well before the evening does.
Yesim: full speed until 5 GB per day
Yesim is more explicit: its unlimited Europe plans carry a fair-use threshold of about 5 GB per day at full speed — after that you are throttled to roughly 2 Mbps until the counter resets at midnight UTC. 2 Mbps is fine for messages and maps; it is not fine for HD streaming, video calls or a hotspot with a laptop behind it.
Why every “unlimited” plan works like this
There is no villain here — just economics. Providers pay carriers per gigabyte, so a flat “unlimited” price only works if heavy users are slowed down. The problem is the word on the checkout page: the limit is real, it has just moved into the fine print. If your usage is light, you will never notice. If you bought “unlimited” precisely because you use a lot, you are the person the policy is written for.
| Holafly Europe (per their FAQ & reviews) | ±2–3 GB/day full speed · hotspot ±500 MB/day |
| Yesim Europe (per their help center) | 5 GB/day full speed, then ±2 Mbps |
| HyperMobile | 50–500 GB, full speed to the last GB, hotspot free |
| The pattern | the cap lives in the fine print |
The honest comparison
Do the math the way your month actually works. A 3 GB/day allowance is at best ~90 GB per month — but only if you spread usage perfectly evenly, every single day. Real usage is lumpy: a rest-day binge, a rainy Sunday in the camper, a weekend of hotspotting. A transparent bundle flips the logic: one big pool of 50–500 GB you can spend in any rhythm, at full speed, with the hotspot open. When it runs out, you top up — no surprises, no slow lane.
Check any “unlimited” plan in 2 minutes
- Search the terms for “fair use”, “FUP”, “Mbps” and “kbps” — the real limit lives there
- Find the daily full-speed allowance and multiply by 30: that is your effective bundle
- Check the hotspot/tethering cap separately — it is often much lower
- Note the reset time (usually midnight UTC), not midnight local time
- Compare that effective total against a transparent bundle with hard numbers
We built HyperMobile on the opposite promise: a real number, all high-speed, hotspot open. If your month needs more than the fine print allows — compare our transparent EU bundles here.
