The biggest name, reviewed honestly

Airalo in Greece

The world's best-known eSIM brand is a fine city pick for Greece, with one structural weakness the marketing skips.

Plaka, Athens · Nova is fine here
Quick answerAiralo in Greece runs on Nova and Vodafone, not Cosmote. For Athens, Thessaloniki and the big islands that is fine, and the $4 entry plan and $12 five-gig week are genuinely cheap. For small-island hopping, Saily's Cosmote access is worth the extra $3. Trustpilot 4.1 from 41,000+ reviews. Checked August 31, 2026.

Airalo's real wins are the two ends of the spectrum: the cheapest short plans and the widest ecosystem. The middle of the market, where most two-week Greek holidays live, belongs to GigSky on price and Saily on network.

Coverage in Greece what "no Cosmote" means

WhereWhat to expect on Airalo
Athens, ThessalonikiExcellent; Nova 5G in the center, Vodafone as fallback, indistinguishable from pricier rivals
Big islands (Crete, Rhodes, Corfu, Santorini)Good in towns and resort corridors on either network
Small islands, hill interiorsThe gap: Nova fades first here and Vodafone does not fully close it; expect dead zones Cosmote users do not have
FerriesSignal drops earlier offshore than on Cosmote; download offline maps before boarding

That is not a flaw of the app, it is the network deal, and it is the reason Airalo sits third on our main ranking despite the best brand recognition in the business.

Buying and activating one rule matters

  1. Buy on airalo.com in your browser, at home on wifi. One honest disclosure: website purchases are how our links track; the checkout is identical either way, so this costs you nothing and keeps the site running.
  2. Install via the emailed QR or the site flow, label the line "Greece", toggle it off until you land.
  3. On arrival: line on, data roaming on for the Airalo line only. It registers on Nova by default.
  4. Weak signal off the beaten path? Try pinning Vodafone GR manually in network settings; on remote islands, accept that this is Airalo's ceiling.

Buy it or skip it the honest split

Buy Airalo if

It is your first eSIM: the most guides, translations and answered questions of any brand.

Your trip is a city break or a short week: $4 and $12 plans are unbeaten there.

Your route adds Turkey or the Balkans: Eurolink is the only one-plan answer among our five.

Skip Airalo if

You are island-hopping beyond the big names: no Cosmote is a real ceiling. Saily exists for this.

You want the cheapest 10–30GB: GigSky and Yesim undercut it by 20–30%.

You hotspot daily: a 3GB/day unlimited cap is tight against Saily's 5GB.

Questions on Airalo

Which network does Airalo use in Greece?

Nova and Vodafone, per Airalo's own plan details. No Cosmote. Cities and large islands are well covered; the smallest islands and ferry routes are where the gap shows.

Is Airalo's unlimited really unlimited?

It is 3GB per day at full speed, then 1 Mbps until midnight. Enough for maps and messaging after the cap, not for video. Saily's cap is 5GB/day for similar money.

Airalo or Saily for Greece?

Short city trip: Airalo, it is a few dollars cheaper. Islands, ferries, longer stays, hotspot: Saily, for the Cosmote coverage and the bigger unlimited cap.

Does Airalo data roll over or top up?

Plans can be topped up in the account before expiry, and the 50GB and 100GB tiers exist precisely for people who hate rebuying. Unused data does not roll past the validity window.

Why do reviews mention Airalo price increases?

Long-time users note that plan prices have crept up over the years, which shows in the middling 4.1 Trustpilot score despite the huge review count. In Greece specifically, the short plans remain competitively priced; the 10GB tier is where rivals undercut it.

Does Eurolink cover Greece AND Turkey on one eSIM?

Yes: 42 countries including both, plus the Balkans and Georgia. It is the one plan among our picks that survives a Kos-to-Bodrum ferry day-trip without a second eSIM. Per-GB it costs more than Greece-only plans, so buy it for the route, not for Greece alone.
