eSIM Fair Use Audit 2026: What Unlimited Really Means
“Unlimited” on an eSIM listing never means unthrottled. We audit the fair-use policy of every unlimited plan in our database — recorded verbatim at check time — and publish what each provider's small print actually does.
Every “unlimited data” eSIM carries a fair-use policy (FUP) — a threshold or heuristic that can slow your connection long before the calendar runs out. Providers rarely hide these policies, but they do bury them. This audit pulls the fair-use note from every unlimited plan in our database, quotes it verbatim, and grades each provider on whether its listings actually state one. If you only remember one thing: unlimited is a billing term, not a speed promise — see the audit table for what your provider says.
The audit
What each provider's unlimited really means
| Provider | Unlimited plans tracked | With explicit FUP note | What the note says | Verdict |
|---|---|---|---|---|
| Airalo | 277 | 277/277 |
“3 GB per day at full speed, then ∞ at 1Mbps” “5 GB per day at full speed, then ∞ at 1Mbps” |
transparent |
| aloSIM | 279 | 279/279 |
“3 GB per day at full speed, then ∞ at 1kbps” |
transparent |
| Holafly | 298 | 298/298 |
“Always On backup plan: 1GB of data monthly to keep you connected no matter what.” |
transparent |
| Roami | 172 | 0/172 | no note on any tracked listing | unstated |
| Roamic | 1500 | 1500/1500 |
“3 GB per day at full speed, then ∞ at 1Mbps” “3 GB per day at full speed, then ∞ at 384kbps” |
transparent |
| Saily | 227 | 227/227 |
“3 GB per day at full speed, then ∞ at 1Mbps” “5 GB per day at full speed, then ∞ at 1Mbps” +2 more variants |
transparent |
| Ubigi | 36 | 31/36 |
“5 GB per day at full speed, then ∞ at 2Mbps” “60 GB per month at full speed, then ∞ at 2Mbps (auto-renewing monthly subscription)” |
partial |
| Yesim | 1386 | 0/1386 | no note on any tracked listing | unstated |
“Verdict” reflects only what a provider's own listing states at check time: transparent = every tracked unlimited plan carries an explicit note; partial = some do; unstated = none do. We do not paraphrase or interpret policies — notes are quoted verbatim.
Before you buy
Four things to check on any unlimited plan
1 · The daily rate rather than the sticker price
Divide the price by the days. The unlimited league table does this for every country we track.
2 · Whether a fair-use note exists at all
A listing with no FUP note isn't a promise of unthrottled data — it just means the seller didn't state one. Treat “unstated” as “unknown”, not “none”.
3 · Hotspot sharing rules
Tethering is where fair-use policies bite hardest. Some plans allow it, some throttle it, some drop it after a threshold — it's in the per-plan notes on each country page.
4 · Whether a big metered bucket is cheaper
If your usage is predictable, a 20GB metered plan often beats unlimited on price. Check both tables on your destination's page before committing.
FAQ
How do you spot a fair-use catch before you buy
What does fair use mean on an unlimited eSIM?
Fair use is the provider's right to slow down or manage your connection — a daily full-speed allowance, a monthly threshold, or a congestion heuristic. It is how 'unlimited data' plans stay profitable. Of the 4175 unlimited plans we track, %!d(float64=63)% carry an explicit note on the listing; the rest simply do not say, which we grade as unstated rather than unlimited.
Which eSIM providers state their fair-use limits?
Airalo, aloSIM, Holafly, Roamic and Saily state an explicit note on every unlimited plan we track from them; Ubigi state one on only some listings. The audit table above quotes each provider's actual wording — we never paraphrase a policy into something friendlier than it is.
Can I be throttled even with unlimited data?
Yes — that is exactly what fair use allows. A plan can carry unlimited gigabytes and still slow you down after a threshold, on congested towers, or for tethering. Before a heavy trip, check two things on the country page: the verbatim note on each plan row, and whether a big metered bucket is simply cheaper for your usage.
