Greece has it all: 6,000 islands (227 inhabited), 3,000 years of Western civilisation visible in one city, the world's most photographed sunset in Oia, the best fresh seafood on any Mediterranean table, and summer weather that makes everywhere else feel like a consolation prize. The islands require planning — ferries, not planes, connect most of them, and ferry schedules change seasonally.
Network Coverage in Greece
Greece has three carriers: Cosmote (widest, best island coverage), Vodafone GR, and Wind Hellas. Our Europe eSIM connects to Cosmote — Greece's strongest network. Athens: excellent 4G/5G. Santorini (Oia, Fira, Akrotiri): Cosmote excellent. Mykonos: excellent. Crete (Heraklion, Chania): excellent on north coast. Rhodes: excellent. Corfu: excellent. Remote smaller islands (Folegandros, Amorgos): Cosmote adequate in main villages. Open sea between islands on ferry: limited signal mid-crossing.
Island Ferry Navigation — Where Data Is Critical
- Ferryhopper.com — best ferry booking platform, real-time schedule updates essential (Greek ferries delay frequently)
- OpenSeas app — live ferry tracking, know your boat's actual arrival
- Google Maps offline Greece — download each island before the ferry, port towns are complex to navigate
Athens in Detail
The Acropolis requires advance online booking at odeion.gov.gr — it sells out in summer. The ticket includes entry to 6 additional ancient sites (Agora, Kerameikos, etc). Download the QR code before you go. Athens Metro: Cosmote signal good at most stations. The Plaka neighborhood below the Acropolis: narrow streets, Google Maps essential for ruin-hopping.
Santorini Specific Tips
Oia village: Cosmote 4G excellent — stream your sunset live if you want. The famous caldera sunset viewpoint crowds: signal remains good despite thousands of people (Cosmote handles congestion better than others). Akrotiri archaeological site: book online, need data for QR code. Boat tours of volcanic islands: signal at Nea Kameni (active volcano), drops mid-caldera.
