The caps nobody prints
Unlimited eSIM for Greece
Every "unlimited" plan throttles after a daily quota. Here is each one, and the math on when unlimited beats a fixed bundle.
The caps side by side
| "Unlimited" plan | Real daily high-speed cap | After the cap |
|---|---|---|
| Saily Unlimited: $18.99/5d · $34.99/10d · $48.99/15d · $71.99/30d | 5GB / day | throttled to crawl until midnight |
| Airalo Unlimited: $10/3d up to $71/30d | 3GB / day | 1 Mbps, maps and chat still work |
| Yesim Unlimited: $4.06/1d up to $66.06/30d | not published | "may be throttled after heavy usage" |
| Holafly Unlimited (not sold via our partners) | not published for Greece | daily throttle per their fair-use policy |
A cap you can read beats a bigger cap you can't. We rank published caps above unpublished ones on principle: you can plan a workday around 5GB, you cannot plan around "heavy usage".
The math unlimited vs fixed GB
Unlimited has a premium. Whether it is worth paying depends on one number: your real daily usage.
| Your day looks like | Real usage | Cheaper option |
|---|---|---|
| Maps, messages, photos, some social | 0.5–1GB/day | GigSky 10GB at $18.29 covers 2+ weeks |
| Video calls home every evening | 1.5–2GB/day | 20GB bundle still wins for trips up to 10 days |
| Hotspot for a laptop, streaming, uploads | 3GB+/day | Saily Unlimited, and only Saily's 5GB cap actually fits this |
Rule of thumb: under 1.5GB a day, fixed bundles win on price every time. Check how many GB you actually need before paying the premium.
Questions on unlimited
Is Holafly worth it for Greece?
Holafly is the best-known unlimited brand, but its Greek daily cap is not published, and it is not sold through our partners, so we have no reason to soften this: with Saily you know you get 5GB/day at full speed for similar money. We prefer the number we can verify.
Does hotspot work on unlimited plans?
Yes, but the daily cap is what limits you. A laptop workday eats 2–3GB, so Saily's 5GB/day handles it and Airalo's 3GB/day is tight. After the cap, tethering slows with everything else.
Does the throttle reset?
Yes, daily. Burn the cap at lunch and you crawl until midnight local time, then full speed returns.
