Does it work on the Athens metro and out to Piraeus?

It does. Coverage is strong across central Athens, the metro lines and down to Piraeus port, though signal can briefly drop in deeper tunnel sections. Load your ferry tickets and directions before heading underground to be safe.

How much data do I need for a few days in Athens?

For a typical city break of maps, ride-hailing, social posts and restaurant bookings, most travellers are comfortable with 1-3GB. Stream video or hotspot a laptop and you'll want more - the same Greece plan also covers day trips beyond the city.

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Athens eSIM: your local data guide.

Athens rewards the well-connected traveller: you'll want live data to navigate the tangled lanes of Plaka, book Acropolis and Acropolis Museum tickets before the queues build, and check metro times from the airport into Syntagma. An Athens eSIM keeps Google Maps, ride-hailing and quick Greek translations running from the moment you land at Eleftherios Venizelos.

One eSIM for Athens and all of Greece. It's the national Greece eSIM — from $2.15/day with unlimited data, working the same in Athens as it does the moment you leave it.

Landing at Athens International Airport Eleftherios Venizelos (ATH)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

How much data for Athens

For a short city break of walking maps, taxi apps and posting photos, 3-5 GB comfortably covers a few days; if you will stream, tether a laptop or stay a week, choose Unlimited for peace of mind.

Coverage in Athens

Athens has strong 5G across the centre, the airport and the coastal tram line, and coverage reaches most metro stations, though signal can drop briefly in the deeper tunnels between stops on the older lines.

Peace of mind

Your Athens eSIM: data-only, zero bill shock.

Your Athens eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Athens, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
