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.

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: 20 GB for $19.90 gives you ~1.4 GB per day across two weeks — more than most people use — at $1.00 per gigabyte, 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 for AeroSims’ few extra dollars on a week: a published 5 GB/day full-speed allowance instead of an undisclosed cap, hotspot without a separate limit (Holafly caps tethering around 500 MB/day — painful if your travel partner navigates off your phone), and a 30-day 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 $19.90) 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 with no separate cap on both plan types. Holafly limits tethering to roughly 500 MB/day.

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 $19.90, 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.
