Holafly vs AeroSims for Greece (2026): The Honest Island-Hopper’s Comparison
Holafly vs AeroSims for Greece (2026): The Honest Island-Hopper’s Comparison
Updated July 2026 · Prices verified at provider checkouts and subject to change
Here’s a comparison page that will actually tell you when the competitor is cheaper. On unlimited plans, Holafly and AeroSims are close to a draw for Greece: the real money is in what kind of plan you buy. If you’re island-hopping from Athens to Santorini this summer, two minutes here will save you real money.
The quick verdict
For most Greece trips, skip unlimited entirely: AeroSims’ fixed Greece data packages are the price story here, 10 GB for $8.90 or 20 GB for $16.90 (valid 30 days). Twenty gigabytes covers two heavy weeks of maps, ferries, reels and video calls for about a quarter of any unlimited plan.
If you truly want unlimited: it’s nearly a tie. A 7-day plan costs $28.31 at AeroSims vs ~$27.30 at Holafly, and on 15/30 days Holafly is actually a few dollars cheaper. AeroSims’ edge is on terms: a fair-use policy set by the local network, hotspot included, and a money-back guarantee.

First, an honest question: do you even need this?
If you live in the EU, probably not. Your home plan already roams free in Greece. This comparison is for everyone else: travelers from the US, Canada, Australia, the Gulf, and anyone on a UK plan that now bills EU roaming by the day. For you, the math below beats $10–15/day carrier passes by an order of magnitude.
Why the fixed package is the real Greece winner
Greece trips are ferry-timetable trips: Athens for two days, then Naxos, Paros, Santorini. Your data pattern is bursts: heavy on travel days (maps, FerryHopper, bookings), light on beach days. That’s exactly what a big fixed package is for: enough data for the whole trip, without paying for unlimited capacity you won’t touch.
Both AeroSims plan types ride Greece’s major networks (Vodafone and Nova/Wind, with 5G in cities and automatic switching), which matters between islands, where one network can be strong at the port and another up in the chora.
When unlimited does make sense, and who wins then
Content creators uploading 4K daily, remote workers on video calls, families hotspotting three devices: that’s unlimited territory. Here’s the honest math: at 7 days it’s a coin flip ($28.31 vs ~$27.30); at 30 days Holafly is genuinely cheaper (~$74.90 vs $91.63). What you get on the AeroSims side: a fair-use policy set by the local network, hotspot included, and a money-back guarantee.
If those terms matter to you, AeroSims wins on substance. If the lowest 30-day unlimited sticker price is all that matters, Holafly takes that one. We’d rather tell you than have you find out.
Coverage across the islands
Athens, Thessaloniki, Crete, Rhodes, Corfu and the whole Cyclades circuit have strong 4G/5G. Signal dips mid-crossing on longer ferry legs and in mountainous interior villages, normal for every provider in Greece. Download offline maps for ferry days and you’ll never notice.
Greece eSIM questions travelers ask
Which is cheaper for Greece: Holafly or AeroSims?
On unlimited: roughly a tie at 7 days, Holafly cheaper at 30. But AeroSims’ fixed packages (10 GB $8.90, 20 GB $16.90) undercut both unlimited options by 60–75% for typical usage. That’s the plan most Greece travelers should actually buy.
Does the eSIM work on the ferries between islands?
Near ports and along coastal routes, yes; expect gaps mid-crossing on open water. Coverage resumes automatically as you approach the next island.
I’m from the EU. Should I buy anything?
Usually no: EU plans roam free in Greece. Check your plan’s fair-use volume though. Some carriers cap roaming data below your home allowance; a cheap 10 GB package is a good top-up if so.
Can I share data with my travel partner?
On AeroSims, yes. Hotspot is included.
When does my plan start?
When the eSIM first connects to a Greek network, not at purchase. Install at home before you fly; the QR arrives by email seconds after checkout.

Bottom line
Greece isn’t a destination where you need to overpay for the word “unlimited”. Buy the 20 GB package for $16.90, spend the savings on a sunset table in Oia, and if you really do stream all day, pick your unlimited by terms, not just sticker price.
