Greece
Mainland Greece and the big islands are well covered, but island-hopping is where eSIM choice matters: ferry crossings and smaller islands expose weak partner networks quickly.

On the ground
Greece has three operators: Cosmote, Vodafone and Nova, all with solid 4G and growing 5G in the larger cities.
Cosmote is widely regarded as having the best island and rural coverage, which matters given Greece's scattered geography.
Athens and Thessaloniki have strong 5G, while many smaller Aegean islands still rely on more limited 4G towers.
Mountainous parts of the Peloponnese and Crete's rugged interior can lose signal entirely away from coastal towns.
Popular destinations
Athens combines the Acropolis with a 5G-covered city centre, making it an easy base for connectivity.
Santorini and Mykonos draw huge summer crowds that strain local towers even where base coverage is good.
Crete's coastal resorts have dependable signal; its mountain villages often do not.
Corfu and Rhodes mix lively towns with quiet coves where speeds drop off quickly.
Local or regional
A Greece-only eSIM suits island hopping confined entirely to Greek waters.
If the trip also includes Italy or a wider Balkans route, a Europe regional plan saves switching profiles.
Regional data is handy on cruise itineraries that touch several countries in a single week.
For a straightforward Athens-and-islands holiday, the local plan is simpler and cheaper.
