Stay connected at Athens Eleftherios Venizelos International Airport — free WiFi, eSIM options and local data for Greece.

Airport WiFi at ATH

Network
ATH Free Wifi
Good

No registration required — connect and browse immediately.

Each session is capped at 120 minutes, but you can simply rejoin for another block afterward — a personal eSIM is only worth adding if you need one uninterrupted long session rather than a fresh connect every two hours.

Insider tip

Join the 'ATH Free Wifi' network and click through the Internet Access banner rather than looking for a login form — access is terminal-wide and runs 24 hours, so reconnect after the 120-minute session timer rather than assuming you're cut off.

WiFi network names and session limits change frequently. Verify current details at the airport information desk or official website.
