Where your free eSIM works in Greece

Strong 4G/5G across the cities and neighbourhoods most travellers actually visit.

  • Athens

    Metro lines 2 + 3 carry signal through their tunnels; line 1 (ISAP) is largely above-ground from the port to Monastiraki anyway.

    • Plaka
    • Monastiraki
    • Koukaki
    • Exarchia
    • Kolonaki
  • Thessaloniki

    Compact seafront promenade walkable end-to-end in 40 min; the new metro (opened 2024) added 5G across every station.

    • Ladadika
    • Ano Poli
    • Aristotelous
  • Heraklion

    Crete’s capital — base for day trips to Knossos and the Lasithi Plateau; Cosmote 5G covers Liberty Square and the old port.

    • Old Town
    • Lions Square
    • Venetian Harbour
  • Santorini

    Fira–Oia caldera edge gets congested cells at sunset crowds (Jun–Sep); Imerovigli viewpoint is usually quieter and well-covered.

    • Fira
    • Oia
    • Imerovigli
    • Pyrgos
  • Mykonos

    Chora’s narrow streets have full 5G; signal still reaches Super Paradise + Paradise beach clubs on the south coast.

    • Chora (Mykonos Town)
    • Little Venice
    • Ano Mera

What to install before you land in Greece

The eSIM gets you online — these are the local apps it unlocks the moment you arrive.

  • OASA Telematics

    Official Athens metro + bus + tram tracker. Buy single-ride or 24-hour ATH.ENA cards in-app; arrivals refresh every 15 seconds.

  • Ferryhopper

    The Greek island ferry app — every route across the Aegean and Ionian, with price comparison between Blue Star, Seajets and Hellenic Seaways. Book day-of for last-minute hops.

  • Beat

    Athens-born rideshare dominant locally; Uber pulled out years ago. Free Now also operates and dispatches licensed yellow taxis.

  • Hellenic Train

    Use only for the Athens–Thessaloniki main line and the Pelion narrow-gauge runs. Inter-island travel is exclusively ferry-based.

Local prepaid SIM vs. our free eSIM in Greece

What you’d pay at the airport SIM kiosk — and what you save by activating the eSIM before you fly.

ID required — Passport registration in-store since 2020 — Cosmote, Vodafone, kiosks like Germanos / Public all enforce it.

Same data + validity as our free plan, but you spend €10 and queue at a Cosmote shop. The eSIM is the simpler door.

Free eSIM for Greece FAQs by co:sim

Everything you need to know about the free new-user eSIM offer.

Does the free eSIM work on Greek islands?
Yes. Coverage extends across every island group — Cyclades, Dodecanese, Ionian, North Aegean and Crete. Cosmote is dominant on the islands, with full 4G in main towns and 5G in tourist hubs like Fira, Mykonos and Heraklion.
Will it work on the ferry from Piraeus to Santorini?
Only partly. Cosmote’s maritime signal reaches ~25 km off the coast on either end; open-sea stretches in the middle drop for 2–3 hours. Texts queue and sync once reconnected; video calls aren’t realistic mid-Aegean.
Does it work on the Athens Metro?
Yes. Lines 2 and 3 use in-tunnel antennas keeping 4G alive between stations, including the airport-to-Syntagma stretch. Line 1 (old ISAP) is mostly above-ground anyway.
How is coverage in mountain villages like Meteora, Pelion or Zagori?
Paved roads stay reliably covered and Meteora monastery car parks have full signal. Walking trails between monasteries and stone-village footpaths drop out — pre-download offline maps for the hikes.
Does the eSIM cover Cyprus if I hop over from Greece?
Yes — Cyprus is one of the 33 EU countries in the same free plan. No separate profile, no manual switch; just the same eSIM in a Cypriot tower’s arms.
Who's eligible for the free eSIM?
New users who have not previously claimed a free eSIM. Eligibility is verified at checkout.
Will I be charged anything?
$0 is charged for the free eSIM. A valid card is collected at checkout for verification only — this prevents the same person claiming multiple free eSIMs. You only pay if you choose to top up later.
How long is the free eSIM valid?
Install and activate the eSIM within 30 days after purchase. Once activated, the free plan is valid for 7 days from your first connection. After that, top up anytime to extend the validity — the same eSIM keeps working.
Can I top up or buy more data after?
Yes. Top up the same eSIM with any paid plan at any time — your data and validity extend instantly, no reinstall required. You can also buy plans for any of our 190+ other destinations.
Can I claim the free eSIM again?
No. This free eSIM is a new-user offer, so it can only be claimed once.
How does the free plan compare to paid plans?
Same high-quality network coverage. Paid plans offer more data and longer validity — and you can top up onto your free eSIM at any time.
