Why Travelers Choose an eSIM for Greece
Island-hopping Santorini, Mykonos and Crete or exploring Athens and the Acropolis? A Greece eSIM connects to Cosmote, Vodafone Greece or Nova the moment you land at Athens International (ATH), Santorini (JTR), Mykonos (JMK) or Heraklion (HER). Activate a plan in two minutes, scan the QR code, and you're online for ferry timetables between Paros and Naxos, Google-mapping Acropolis entrances, or posting Oia sunset photos from a cliff-top taverna. Choose a 7-day 3 GB plan for a Santorini + Athens weekend, a 30-day 10 GB plan for a full Cycladic island tour, or Greece eSIM unlimited data if you're working remotely from a Crete villa.
eSIM vs Greek Tourist SIM ā Which Works Best for Island Hopping?
Greek carriers (Cosmote, Vodafone Greece, Nova) sell tourist SIMs at Athens airport, but an eSIM for Greece travel is faster to activate and keeps working across the Cyclades without needing to reload or buy multiple SIMs.

Greece eSIM FAQ ā Island Coverage, Cosmote/Vodafone & Athens Tips
Which is the best eSIM for Greece?
The best eSIM for Greece depends on your itinerary ā a 7-day 3 GB plan covers a Santorini + Athens weekend with Oia sunset photos and Acropolis tickets, a 30-day 10 GB plan fits a full Cycladic or Dodecanese island tour, and Greece eSIM unlimited data is ideal for summer nomad stays on Crete or Rhodes. Our Greece eSIMs run on Cosmote (OTE) and Vodafone Greece, so 4G/5G coverage is strong in Athens, Thessaloniki and all major tourist islands.
Does a Greece eSIM work on small islands like Milos or Koufonisia?
Yes ā our Greece eSIM runs on Cosmote and Vodafone Greece, which together cover nearly every Aegean and Ionian island with at least 4G. Expect strong signal on major islands (Mykonos, Santorini, Crete, Rhodes, Corfu) and solid 4G on smaller ones (Milos, Paros, Naxos, Ithaca). Remote beach coves and uninhabited skerries may drop to 3G or lose signal briefly ā normal for any SIM on those islands.
Can I get unlimited data for a month in Greece?
Yes ā our Greece eSIM unlimited data plans offer full-speed 4G/5G up to a daily fair-use cap (usually 3 GB/day), then continue at reduced speed with no hard cutoff. Ideal for longer Greek summer stays ā digital nomads on Crete, month-long island-hop itineraries, or remote workers settling in Athens for a summer season.
