A travel sim Greece plan from HelloRoam covers Greece from A$3.07 on Wind and Vodafone 5G networks. Plans activate by QR code at home before you fly from Australia.

Greece eSIM with fast 5G coverage

Heading overseas? HelloRoam takes the stress out of getting mobile data sorted before you fly. Getting online from the moment you land in Athens is easy with a HelloRoam eSIM. You buy your plan before you leave home, scan the QR code, and arrive with data already active on your device. HelloRoam's Greece plans connect to Vodafone Greece and Wind Hellas, both of which operate 5G in Athens and 4G across the islands. Coverage reaches to Santorini, Mykonos, Crete, Rhodes, Corfu, and dozens of other islands. Ferry crossings between islands lose signal in open water, and the most remote smaller islands rely on 3G. But for the main routes every traveller takes, the connection is solid. A HelloRoam eSIM gives you a prepaid flat rate across all of Greece without tying you to a home carrier's daily travel add-on.

Greece is a bucket-list destination for many Australians, from the ancient ruins of Athens to the iconic blue-domed churches of Santorini and the crystal waters of Mykonos, Rhodes, and Crete. Cosmote, Vodafone GR, and Wind Hellas provide 4G and 5G coverage across the mainland and major islands.

Smaller and more remote islands can have limited signal. A HelloRoam eSIM gets you connected at Athens International from the moment you land.

eSIM Travel Tips for Greece

Greek island coverage varies
Popular islands including Santorini, Mykonos, Corfu, Rhodes, and Crete all have solid 4G coverage in main towns and resort areas. Smaller islands in the Cyclades and Dodecanese can be patchy. Remote beaches and hiking paths on larger islands can also drop out. Download offline maps before each island.
Ferries and inter-island travel
Greek island ferries can be slow and schedules change with sea conditions. Download your ferry booking confirmations and port maps offline before each trip. Mobile signal is generally available in ports but can drop at sea on longer crossings.
Athens heat and ancient sites
Athens in summer can reach 40 degrees Celsius. Keep your phone out of direct sun. The Acropolis, Parthenon, and Agora have crowds and poor shade. Download audio guides and site maps offline so you are not battling crowds while loading pages in the heat.
Greek food and restaurant navigation
Finding authentic tavernas away from the tourist strip is best done through Google Maps local reviews. Having data running lets you check ratings for family-run tavernas in the backstreets of Athens' Monastiraki or down Santorini's less-travelled paths.
Travel insurance for Greece
Australia has no reciprocal healthcare agreement with Greece. Travel insurance with comprehensive medical cover is essential. Greek hospitals in popular tourist areas are generally good but medical evacuation costs can be significant. Register with smartraveller.gov.au.

Mobile networks in Greece: Cosmote, Vodafone GR, and Wind Hellas

Greece has three main carriers. Cosmote (part of Deutsche Telekom) has the widest coverage nationally including rural mainland and many smaller islands. Vodafone GR and Wind Hellas cover major cities and tourist islands well. All three offer 4G with 5G rolling out in Athens and Thessaloniki. Your HelloRoam eSIM connects to the strongest available signal.

Wind: 5G
Vodafone: 5G

Best time to visit Greece from Australia

Greece's best seasons for Australians are late spring (May to June) and early autumn (September to October), when temperatures are comfortable, the sea is warm, and the island crowds are more manageable. July and August are peak tourist season with extreme heat and crowds on Santorini and Mykonos. Winter is quiet and some islands close down almost entirely. The Greek summer aligns with the Australian mid-year school holidays, making July a popular month for Australian families despite the heat.
