Best eSIM for Greece: 6 Providers Compared (Real Prices)

Every summer I watch the same thing happen on the ferry from Piraeus: someone spends the first twenty minutes of a five-day island trip hunting for wifi at the port instead of just buying an eSIM before they left home. I'm Greek, I live in Athens, and testing eSIMs for my own hopping between Athens, the islands, and the rest of Europe is basically a hobby at this point. Here's the real pricing across six well-known providers we track, checked directly against Greece-specific listings rather than generic "Europe" pricing that doesn't actually apply here.

The quick answer

• Cheapest unlimited data for a full month: eSIMCard at $22.75 — well ahead of Maya Mobile's flat rate at $49.99.
• Cheapest unlimited data for a week: eSIMCard again, at $7.72.
• Best value if you don't need unlimited: Ubigi — its Greece fixed-data tiers are some of the cheapest in this whole comparison.
• Cheapest single entry point: Airalo's 1GB for 3 days at $4.00.

What you'll actually pay: six providers compared

Airalo

Airalo's Greece lineup is built around short trips and island-hopping durations rather than a single flat monthly rate. A 1GB/3-day plan is $4.00, and 3GB stretches to $8.50 for 3 days or $9.00 for a full week. The middle tiers are solid value too — 5GB for a week is $11.00, 10GB for a week is $19.00 — and the 30-day options run from 5GB at $12.00 up to 50GB at $42.00. If you want unlimited instead, it's $11.50 for 3 days, $27.00 for a week, and $69.00 for 30 days.

eSIMCard

eSIMCard's Greece pricing is unlimited-only, priced by duration — and it's genuinely the standout on this list: $1.74 for a single day, up through $22.75 for a full 30 days, undercutting every other unlimited option here at essentially every length. If unlimited is what you want, this is the one to check first. Real discount code active:

Nomad eSIM

Nomad eSIM's Greece unlimited plans stop at 10 days ($33.00) — there's no 30-day unlimited tier here, which is worth knowing if you're planning a longer stay. What it does have is genuinely good fixed-data pricing: 20GB for 30 days is $21.00, and 50GB for 30 days is $31.00, both of which comfortably beat the equivalent Airalo and Saily tiers. For a monthlong trip where you don't need unlimited, Nomad eSIM is one of the stronger picks. Real discount code active:

Nomad eSIM -15% ESIMKART15

15% off, single-use per customer. Excludes plans under $5, sale plans, add-on data, unlimited plans, and the Thailand 50GB plan.

Saily

Saily's Greece pricing runs unlimited by duration — $18.99 for 5 days up through $59.99 for 30 days, with steps at 7, 10, 15, 20, and 25 days along the way. On the fixed-data side, a 1GB/7-day plan at $4.49 is a reasonable light-use option, and the 30-day tiers (3GB at $9.99, 5GB at $13.99, 10GB at $21.99, 20GB at $37.99) sit in the middle of the pack — not the cheapest, not the most expensive.

Ubigi

This is the one I point Greek friends to when they ask what to actually buy. Ubigi's fixed-data Greece pricing is aggressive: 3GB for 30 days is $6.00, 10GB for 30 days is $12.00, 25GB for 30 days is $22.00, and 50GB for 30 days is $32.00 — each of those beats the equivalent tier from most other providers we checked. Its unlimited tiers (7 days at $22.00) are useful too, just not quite the standout that the fixed-data side is. Real discount code active:

Ubigi -10% ESIMKART10 First payment only

Maya Mobile

Maya Mobile's flat global rate — the same $9.99/3 days, $19.99/7 days, $27.99/14 days, $49.99/30 days it charges everywhere — is convenient but no longer the cheapest unlimited option in Greece specifically; eSIMCard now undercuts it at every duration. If your trip includes Greece as one stop among several countries, though, that "one eSIM, one price, everywhere" model is still genuinely useful — you don't buy a new plan every time you cross a border.

Why the prices are all over the place

I get asked this constantly: why is one plan a couple of dollars and another well over $60 for what sounds like the same thing? It's a few different pricing models colliding. eSIMCard prices Greece unlimited aggressively and by the day. Maya Mobile charges one flat global rate regardless of destination, which is convenient for multi-country trips but no longer wins on price here. And Airalo, Nomad eSIM, Saily, and Ubigi all mix fixed-data tiers alongside unlimited, so the right pick depends entirely on how much data you'll realistically use rather than which headline number looks lowest.

My honest advice, having watched friends over-buy for years: unless you're planning to stream a lot of video on the ferry or hotspot a laptop, you probably use far less data on a normal trip than you think. A 10GB or 20GB fixed plan from Ubigi or Nomad eSIM covers most people's actual usage for a fraction of an unlimited price.

How to pick based on your trip

Island-hopping for under a week: Airalo's short-duration data tiers (1GB/3-days at $4.00, 5GB/7-days at $11.00) are built exactly for this and are hard to beat on price for light use.

A week or two, and you want unlimited: eSIMCard at $7.72 (7 days) is normally the cheapest unlimited option we found.

A full month, fixed data is fine: Ubigi's 25GB/30-day plan at $22.00 or Nomad eSIM's 20GB/30-day plan at $21.00 are both excellent value — most people don't come close to using 20GB in a month unless they're streaming constantly.

A full month, you want unlimited: eSIMCard at $22.75 is normally the cheapest, well ahead of Ubigi, Airalo, and Maya Mobile's flat rate.

You're visiting Greece as part of a wider Europe trip: worth reading our Europe multi-country guide — a single regional or global plan (Maya Mobile's flat rate included) can work out cheaper and simpler than buying a new Greece-only eSIM every time you cross into Italy or Turkey.

A few things worth knowing before you buy

Greece's islands don't all have equally strong signal — Athens, Thessaloniki, and the bigger islands like Crete or Rhodes are reliably fast, but some of the smaller Cyclades can have patchier 4G away from the main town. It's rarely a dealbreaker, but don't expect flawless 5G on every beach.

Buy and install your eSIM before you fly. Every provider here lets you activate it only once you land, so there's no reason to wait until you're at the airport hunting for wifi to scan a QR code.

Double-check your phone is eSIM-compatible and carrier-unlocked before buying — our beginner's guide to eSIMs covers exactly how to check in under a minute.
