4G coverage is generally good in cities and major roads. 5G is expanding — available in some capital cities and tech hubs. In practice, most travel eSIMs use 4G/LTE.
Known problem areas
- Smaller Aegean and Ionian islands (Ikaria, Folegandros)
- Mountain hiking routes (Taygetos, Pindus)
- Sea crossings between islands by ferry
- Ancient site interiors with thick stone walls
Coverage by city
- Athens: Good coverage; Acropolis hill and tourist areas well-served.
- Thessaloniki: Second city; solid 4G/5G downtown.
- Santorini: Oia, Fira and main towns covered; caldera boat trips can blip.
- Mykonos: Well-covered; beach parties can saturate local cells.
- Heraklion: Crete main city; Knossos archaeological site well-covered.
- Rhodes: Old Town and resort areas good; remote south coast weaker.
Tip: if you're visiting rural areas or national parks, download offline maps and don't count on permanent signal.
