KEF currently offers free unlimited Wi-Fi with no registration, login or password, so it is a strong setup fallback after landing.
Keflavík & KEF eSIM guide: land at KEF with your first route already online.
Keflavík Airport currently provides free unlimited Wi-Fi across the airport with no login or password. That is useful for retrieving setup details, checking weather or confirming the rental-car route, but a pre-installed eSIM keeps working after you leave the terminal. Pre-installing an eSIM still makes the arrival smoother because your connection can continue when airport Wi-Fi ends and the first transport, ticket or hotel task begins.

Plan around the moments you will actually need data.
Most visitors continue from KEF by coach or rental car, so mobile data is useful immediately for weather, road conditions, maps and accommodation directions.
Eligible EU/EEA plans generally receive Roam Like At Home treatment here within fair-use rules.
