Airport Wi-Fi and an Iceland eSIM are not competing versions of the same service. KEF Wi-Fi solves immediate terminal access; an eSIM can provide mobile data after the traveller leaves the airport.
The correct arrival plan can use both, while keeping transfer information offline in case either fails.
NoveSIM is data-only and does not add an Icelandic number or conventional calls and SMS.
Quick answer: Use verified KEF – FreeWiFi for low-risk terminal tasks, then use a pre-installed eSIM for maps and messages beyond arrivals; keep the transfer independent of both.
