Stay connected at Heraklion International Nikos Kazantzakis Airport — free WiFi, eSIM options and local data for Greece.
Airport WiFi at HER
Registration required to connect — look for the sign-in page after joining the network.
EU/UK travelers usually have roaming included; other visitors should arrive with a Greece/EU eSIM, especially useful given HER's older terminal and inconsistent wifi performance at peak times.
Wifi can slow to a crawl during the summer high season when the terminal is at its busiest — don't count on it for much beyond basic messaging June–September.
