Buying a SIM card at Keflavík International

The counter at KEF is genuinely good

Most of these pages end with "do not buy at the airport". Keflavík earns a more careful answer.

SIMs at KEF are sold through the airport convenience store rather than carrier desks, and our data lists Síminn, Nova and Vodafone Iceland as available. The store sells them 24 hours a day, and Iceland requires no ID for a prepaid SIM — you pay and you leave. The queue runs about eight minutes at peak and two off-peak.

That combination is unusual. A 24/7 outlet matters a great deal at Keflavík specifically, because a large share of its traffic lands at hours when a staffed carrier desk anywhere else in Europe would be dark. If you arrive at 05:30 off a red-eye, there is somewhere open.

Free WiFi is available throughout the terminal, and taxis, buses and coaches all serve the airport for the run into Reykjavík.

We do not hold the store's name or its exact position in the terminal, so we will not guess at either.

Correcting something that was on this page

An earlier version of this page told readers to pick an eSIM provider "with Síminn access" — naming Nomad and Holafly — and to avoid Airalo because it was "Vodafone only". That was wrong, and it is worth spelling out why, because the same claim is repeated widely.

Airalo does not publish a host network for Iceland, or for any country. Its Iceland plans are sold under the product name Nenna Mobile, which is a retail label at checkout, not a carrier. Nobody outside Airalo knows which Icelandic network its plans use. The claim that it sits on Vodafone Iceland was an invention.

Nomad does not publish one either. The Síminn, Nova and Vodafone Iceland names this page once attributed to Nomad came from our own data rather than from Nomad, which names no host network in any of the 47 countries it sells in. Holafly is in exactly the same position: the Síminn and Vodafone Iceland pairing this page once attributed to its listing also came from our data rather than from Holafly, which names no carrier in any of the countries we have read. Saily and eSIMCard publish nothing at all, and eSIM Go has no consumer page on which it could.

The knock-on matters. If your reason for coming to this page is Ring Road or highland coverage, and you want Síminn because it has the widest rural reach in Iceland, then the only way to be certain you are on Síminn is to buy a Síminn SIM. The convenience store at KEF sells them, 24/7, without ID. That is the honest recommendation, and it points at the counter rather than away from it.

The prices

A local SIM at an Icelandic airport typically runs around $20. We do not hold the data allowance attached to that, which is the usual problem with counter pricing.

Against it, these are read directly from Airalo's own site:

Iceland does have a 50 GB plan, and at $0.98 per gigabyte it is comfortably the best value in the country — better than anything the $20 counter SIM is likely to match unless it comes with a very generous bundle.

Saily's Iceland prices were read off its own site on 18 August 2026: 1 GB for 7 days at $3.99 and 10 GB for 30 days at $19.99, the latter three dollars below the figure we used to carry. An eSIM Go row of $34 for 20 GB over 30 days sits in our data and is not an option: eSIM Go sells wholesale to resellers and publishes no consumer price — checked on esim-go.com on 18 August 2026, where there is no basket, no checkout and no per-country page — so its rows cannot be bought or ever verified. See our eSIM Go page. Nomad's 20 GB for 30 days was read off its own site on 17 August 2026 at $20 — this page previously listed it at $35, which nobody had checked and which was wrong. Holafly's unlimited plans run $20.50 for 5 days and $36.50 for 10 days, also verified. Airalo's verified unlimited is $18.50 for 5 days and $34 for 10.

So, buy at KEF or not?

Buy at the airport if you are driving the Ring Road, the Westfjords or anywhere with long empty stretches, and you want a named network you can rely on. The store is open whenever you land, needs no ID, and is the only way to guarantee which carrier you are on.

Buy an eSIM before you fly if you are staying around Reykjavík and the south-west, or if you want more than about 10 GB — the price per gigabyte is not close, and you land connected. See our Iceland hub for the full plan list.
