The simplest answer: install an Iceland eSIM before you land at Keflavik. You skip the shop, you have working data the instant your plane touches down, and you are connected before you collect your rental car for the 50 km drive to Reykjavik. Keflavik does sell prepaid SIM cards at its 10-11 convenience store in arrivals, and it has free terminal WiFi, but both still mean stopping to set up a card while jet-lagged. A travel eSIM activates over WiFi or home data in a couple of minutes and is ready before wheels-down, which matters in Iceland where you often start driving straight from the airport.

SIM and eSIM Options at Keflavik Airport
Keflavik International Airport (KEF) is a single passenger terminal, so you will not be hunting across multiple buildings the way you would at a larger hub. Connectivity options are concentrated in and around the arrivals hall. Here is what is actually available once you clear passport control and customs.
Quick summary
There is no dedicated phone-carrier SIM counter at Keflavik. Prepaid SIM cards are sold at the 10-11 convenience store in the arrivals hall, which is open 24 hours. eSIMs are not sold from a physical rack, but you can buy and install one online over the free airport WiFi the moment you land, which is the same thing you could have done at home.
Prepaid SIM cards at the 10-11
The 10-11 store in the arrivals hall stocks prepaid tourist SIM cards from the Icelandic carriers, typically including Siminn, Nova, and Vodafone Iceland. A common option is a Vodafone prepaid 4G/5G starter kit at roughly 1,790 ISK (about 13 EUR) for around 3 GB of data. Because the 10-11 runs 24 hours, it is the fallback for red-eye arrivals, which matters given how many flights land at Keflavik in the early morning.
Why there is no eSIM kiosk
Like most airports, Keflavik does not sell eSIMs from a stand, because an eSIM is delivered as a QR code by email. You can buy one on your phone the instant you connect to the airport WiFi, but doing that on arrival offers no advantage over installing it at home before you fly. Pre-installing is the cleanest path: you land already online, with no shop visit and no SIM tray to fumble with.
Topping up in Reykjavik
If you do take a physical SIM, you can top it up later at phone shops and the Elko electronics stores in Reykjavik, or through the carrier's app. For most data-only travelers, though, an eSIM that you top up in-app is far less hassle.
Free Airport WiFi at Keflavik (KEF Free WiFi)
Keflavik offers free terminal WiFi, which matters because it is what lets you activate an eSIM or buy a plan online the second you arrive.
Open WiFi settings
On your phone's WiFi screen, look for the network named KEF Free WiFi. No password is required.
Accept the terms
A portal page appears. Agree to the terms and tap through to the internet. When the WiFi icon shows a connection, you are online.
Use it before you leave the terminal
The free WiFi covers the arrivals and departures areas. It can slow down when several flights land at once, but it is enough to flip on your eSIM and confirm maps are working before you head out to the rental cars or the Flybus.
Why the free WiFi is not enough on its own
Airport WiFi stops at the terminal door. The moment you board the Flybus or pull out of the rental lot for the 50 km drive to Reykjavik, you lose it, and the Reykjanes lava fields between the airport and the city are exactly where you want live maps. Public WiFi is also slower and less secure than your own mobile data. Treat KEF Free WiFi as the tool you use to confirm your eSIM is live, not as your connection for the trip.
Keflavik to Reykjavik: Transit and Data Coverage En Route
Keflavik sits about 50 km southwest of Reykjavik on the Reykjanes Peninsula, so the ride into the city is a real 45-minute journey across open lava fields, not a quick hop. There is no train in Iceland, so your choices are the Flybus, a private transfer, a taxi, or your own rental car. This stretch is precisely where you want working mobile data, for navigation, to message your accommodation, and to check road and weather conditions if you are driving.
| Option | Destination | Time | Fare (one way) |
|---|---|---|---|
| Flybus (to BSI terminal) | BSI bus terminal, central Reykjavik | About 45 min | Around 3,999 ISK (~29 EUR) |
| Flybus+ (hotel drop-off) | BSI, then a minibus to your hotel | About 60 to 75 min | Roughly 5,500 to 6,000 ISK |
| Rental car | Anywhere; self-drive | About 45 to 50 min | Varies; fuel plus rental |
| Taxi | Door to door | About 45 min | Roughly 18,000 to 23,000 ISK |
The Flybus is the standard, best-value option: a coach that meets every arriving flight (typically departing 30 to 60 minutes after a flight lands) and runs to the BSI terminal in about 45 minutes for around 3,999 ISK. The Flybus+ upgrade adds a connecting minibus that drops you near your hotel. A taxi is fast but expensive, since Iceland is a pricey country. Most independent travelers, though, pick up a rental car at the airport and drive straight out, which is why arriving already connected is so useful.
Data coverage on the ride in
The Flybus advertises onboard WiFi, but like most coach WiFi it can be slow and shared across a full bus. Cellular data from your own eSIM is far more reliable across the Reykjanes route into Reykjavik, which has solid coverage on all three carriers. If you are self-driving, this is the leg where live navigation, the road.is condition map, and vedur.is weather really earn their keep, so make sure your eSIM is active before you leave the terminal.
Why Install an eSIM Before You Land
There is a clear case for sorting your connection before the plane even pushes back from your home airport, and in Iceland the case is stronger than usual because so many travelers start driving straight from Keflavik.

How to do it
Buy an Iceland eSIM online a day or two before you fly, install the profile while you still have home internet, then leave it switched off until you arrive. When you land at Keflavik, flip the eSIM line on in your settings and you are connected immediately, no KEF Free WiFi login needed. For a self-drive trip, choose a plan that can use Siminn so coverage holds up once you leave the capital. See our Iceland eSIM guide for compatible devices and the best plan by route.
Keflavik SIM Prices vs an eSIM
Here is the money question. The Keflavik 10-11 is convenient, but its prepaid kits are small buckets aimed at light users, not the larger or unlimited data that a self-drive trip needs. Typical 2026 pricing looks like this:
| Where | Typical plan | Price |
|---|---|---|
| Keflavik 10-11 | Vodafone prepaid starter, ~3 GB | About 1,790 ISK (~13 EUR) |
| Keflavik 10-11 | Larger prepaid bundle, ~10 GB | Roughly 3,000 to 4,500 ISK (~22 to 32 EUR) |
| Online eSIM | 5 GB, city and Golden Circle | Around 11 to 18 EUR |
| Online eSIM | Unlimited, 7 days, for a Ring Road loop | Roughly 30 to 45 EUR |
The pattern is consistent: for small data buckets the airport SIM and an eSIM are in a similar price range, but the eSIM removes the shop visit and lets you arrive already online. Where the eSIM pulls clearly ahead is the option self-drivers actually want, an unlimited or large-bucket tri-carrier plan that keeps maps, weather, and SafeTravel open all day. The airport SIM does give you a physical card and an Icelandic number, but for data-only travelers the eSIM wins on convenience and on the plans that matter for a road trip.
The verdict
Buy an Iceland eSIM before you fly, ideally a tri-carrier plan that can use Siminn for the rural reach. Use KEF Free WiFi only to confirm it is live. Keep the 10-11 in mind purely as a backup if your phone turns out not to support eSIM, or if you specifically want a local number. Run the eSIM Finder to pick the right plan for your route and trip length.
Frequently Asked Questions
Where can I buy a SIM card at Keflavik Airport?
There is no dedicated carrier SIM counter at Keflavik. Prepaid SIM cards are sold at the 10-11 convenience store in the arrivals hall, which is open 24 hours and stocks cards from Siminn, Nova, and Vodafone Iceland. A typical Vodafone starter kit is about 1,790 ISK for around 3 GB. eSIMs are not sold from a rack, but you can install one online over the free airport WiFi or, better, before you fly.
Is there free WiFi at Keflavik Airport?
Yes. Connect to the network named KEF Free WiFi, which needs no password. Accept the terms on the portal page and you are online across the arrivals and departures areas. It can slow down when several flights land at once, but it is enough to activate an eSIM and confirm maps are working before you leave the terminal.
How do I get from Keflavik Airport to Reykjavik, and will I have data on the way?
Keflavik is about 50 km from Reykjavik. The Flybus coach meets every flight and reaches the BSI terminal in about 45 minutes for around 3,999 ISK, with a Flybus+ upgrade that drops you near your hotel. Many travelers instead pick up a rental car and drive. The Reykjanes route has solid cellular coverage on all three carriers, so your own eSIM gives far more reliable data than the shared onboard bus WiFi.
Is buying a SIM at Keflavik cheaper than an eSIM?
For small data buckets they are similar: an airport prepaid starter is about 1,790 ISK for roughly 3 GB, and a 5 GB eSIM runs around 11 to 18 EUR. The eSIM pulls ahead on the plans self-drivers want, such as unlimited tri-carrier data for a Ring Road loop at roughly 30 to 45 EUR for a week. The eSIM also removes the shop visit and the SIM swap, so you arrive already connected.
Should I install my eSIM before or after landing at Keflavik?
Install the eSIM profile before you fly, while you still have home internet, then leave the line switched off until you arrive. When you land at Keflavik, turn the eSIM on in your settings and you have data immediately, with no shop visit and no need to log in to airport WiFi first. This matters in Iceland because many travelers drive straight from the airport, so you want navigation live before you reach the rental car.
