Greece eSIM with fast 5G coverage
Flying abroad? HelloRoam gives Irish travellers a simple way to get mobile data without buying a local SIM at the airport. 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.

eSIM Travel Tips for Greece
Activate before your direct flight from Dublin
Ryanair and Aer Lingus both fly directly to popular Greek island airports in summer. Set up your HelloRoam eSIM at home before you fly and enable mobile data when you land. You are on Greek coverage from the moment you step onto the tarmac.
Smaller Greek islands can have limited signal
Popular islands like Mykonos, Santorini, Rhodes, and Corfu are well covered. If you are visiting smaller or less touristed islands like Ikaria, Kasos, or Ithaca, coverage can be limited. Download offline maps for any island-hopping adventures.
Athens is very well connected
Athens has strong 4G and growing 5G coverage throughout the city centre including the Plaka, Monastiraki, and areas around the Acropolis. Uber and Bolt work reliably on a local data connection. The Athens Metro has improving signal in stations.
Keep your Irish number active on holiday
Dual SIM phones let you run your Irish SIM for calls alongside HelloRoam for data. Useful when you need to call Irish numbers or receive calls from home while sitting on a taverna terrace in Crete.
Ferries between islands can drop signal
Greek ferry crossings between islands often lose signal in open water. Download entertainment, offline maps, and any documents you need before boarding a Hellenic Seaways or Blue Star ferry between islands.
Mobile networks in Greece: what Irish travellers need to know

Best time to visit Greece from Ireland
Greece is a summer destination for most Irish visitors with the main season running from May to October. July and August are hot, sunny, and very busy on the popular islands. May, June, and September are ideal for fewer crowds and more comfortable temperatures. Athens city breaks work year-round. The Greek Easter period is culturally rich but accommodation books out fast.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
