Thessaloniki International Airport (SKG) is the main gateway to Northern Greece and one of the busiest airports in the country. Every year, millions of travelers arrive here before exploring Thessaloniki, Halkidiki, Mount Olympus, Kavala, Meteora, or the beautiful beaches of northern Greece.
Having internet access immediately after landing makes your journey much easier. You’ll likely need Google Maps, hotel directions, taxi services, bus schedules, online tickets, WhatsApp, restaurant reservations and navigation before you even leave the airport.
Quick answer: although you can buy a SIM card at Thessaloniki Airport, many international travelers now prefer using a Greece eSIM. It can be installed before departure and activated after landing, eliminating the need to search for a SIM card shop inside the airport.
