Greece is a phone-in-hand kind of trip — ferry timetables that shift with the wind, a taverna down an unmarked Santorini lane, and a hundred photos an hour. Here is how to stay connected across the mainland and the islands without a roaming bill.
The networks
Greece's carriers are Cosmote, Vodafone Greece, and Nova. Cosmote has the widest and fastest coverage, including on most of the islands. A travel eSIM connects you to strong 4G/5G rather than your home carrier's roaming.
Athens & Thessaloniki: Full 4G/5G everywhere — the Acropolis, Plaka, the metro, the ports. No issues.
The islands (Santorini, Mykonos, Crete, Rhodes, Corfu): The popular islands have solid 4G in the towns, at the beaches, and at the big sights (Oia, Fira, Knossos). Signal can thin on remote cliff paths and tiny islands, but for where travellers actually go, it is reliable.
Ferries: Expect coverage near port and along coastal routes, with gaps in open water on longer crossings — normal at sea. Download your tickets and maps before a long ferry day.
Greece plan or Europe-regional?
Island-hopping only in Greece? A single-country Greece eSIM is the best value. Combining Greece with Italy, the Balkans, or a wider Euro trip? A Europe-regional eSIM covers 30+ countries on one plan.
How much data?
- City + one island (5–7 days): 5–8 GB.
- Two-week island hop: 10 GB.
- Heavy user / hotspot: 15 GB+ or unlimited-style.
