Best eSIM for Greece

Greece has three networks — Telekom (formerly Cosmote), Vodafone and Nova (formerly Wind) — and Telekom has the best coverage on the islands. Athens and the big islands are well served on all three; small islands, mountain villages and ferry crossings are where the network your eSIM uses makes a difference.

At a glance

  • Budget pick: Talisim — $8.56 for 10 GB / 30 days on Vodafone and Nova, less than half what Nomad ($18) and Airalo ($20) charge on the same networks
  • Best for island-hopping across borders: Airalo Eurolink — handy if Greece is part of a longer trip through Italy, Croatia or Turkey
  • Best for unlimited data: Holafly Greece — from $27.50 for 7 days, but hotspot is capped at about 500 MB–1 GB a day
  • For cruises: GigSky — its Cruise + Land plans work on board 290+ cruise ships as well as in port (regular country plans don’t work at sea)

Network notes

Telekom — called Cosmote until it rebranded in September 2026 — is owned by OTE, part of the Deutsche Telekom group, and has the widest coverage, especially on smaller islands and in the mountains. Vodafone is a close second. Nova, the rebranded Wind Hellas, is good in Athens, Thessaloniki and the popular islands but thinner in remote spots.

None of the plans we checked use Telekom: Talisim, Nomad and Airalo all run on Vodafone and Nova. That’s fine for Athens, Santorini, Mykonos, Crete, Rhodes and Corfu. If you’re heading to remote islands in the Dodecanese or hiking in the Peloponnese, check which network a plan uses before you buy.

Practical connectivity tips

  • Install before you land. Athens airport Wi-Fi works, but you’ll want data for the metro, a taxi or a ferry booking on arrival.
  • Apps you’ll want online: Ferryhopper (ferry tickets and live changes), FREENOW and Uber (taxis in Athens and Thessaloniki), OASA Telematics (Athens buses), Google Maps, and Windy or Poseidon for sea conditions.
  • Ferries: signal holds near the coast but drops in the open sea between island groups. Download tickets and boarding passes before you sail.
  • Ferry cancellations happen in strong meltemi winds. Keep data handy to rebook — the operators post changes online first.

Watch out for

  • Heat and power cuts on small islands in summer can take a mast offline for a few hours.
  • Mount Athos and parts of the Pindus mountains have very little signal.
  • Day trips to Turkey (Kos–Bodrum, Rhodes–Marmaris, Lesbos–Ayvalik) need a plan that covers Turkey too. EU-only plans don’t, but some Europe-wide plans, including Airalo’s Eurolink, do.
