eSIM for Greece

Yes—install the QR on Wi-Fi before your flight, then enable data after landing at ATH (Eleftherios Venizelos) or SKG (Makedonia) or JTR (Santorini Intl.).. Country plans cover Athens, Thessaloniki, Santorini and major tourist routes.

For international visitors, usually yes—prepaid GB and days are fixed before you travel, with no surprise bill from your home carrier.

Local Cosmote and Vodafone Greece packs work if you need a local phone number. For data-only trips, a travel eSIM offers QR setup before you fly and English checkout.
