Greece eSIM with fast 5G coverage
Heading to Greece? HelloRoam keeps you connected from the moment you land in Athens, without swapping SIM cards or paying UK carrier roaming rates.

Is a Greece SIM card or a HelloRoam eSIM better value for British summer holiday-makers?

eSIM Travel Tips for Greece
Set up your eSIM before your flight to Greece
Install your HelloRoam eSIM profile on your phone before heading to the airport. Switch it on when you land at Athens Airport or step off your island-hopping ferry and you will have data straight away. No need to find a local phone shop or queue at the airport kiosk.
Island-hopping and ferry connections
Greece's ferry network connects dozens of islands across the Cyclades, Dodecanese, and Ionian chains. Main island ports and ferry terminals generally have 4G coverage. Smaller islands like Folegandros, Kasos, or Tilos may have more limited connectivity. Download your ferry timetables and accommodation maps in offline mode before boarding.
Coverage on smaller Greek islands
Major tourist islands like Crete, Corfu, Rhodes, Kos, Mykonos, and Santorini have strong 4G coverage across the main resort areas. Very small or less-visited islands may only have coverage in the main village or port. Check your itinerary and download offline maps if visiting quieter destinations.
GHIC healthcare cover in Greece
British travellers should carry their GHIC for access to state medical facilities in Greece. Keep your HelloRoam eSIM active so you can access medical directories, call your travel insurance company, or locate the nearest clinic when exploring remote areas.
Avoid UK roaming charges across your Greek holiday
UK networks charge daily roaming fees in Greece. Use your HelloRoam eSIM for all mobile data and keep your UK SIM active only for incoming calls and SMS. You stay contactable on your regular number without racking up extra charges from EE, Three, or O2.

Best time to visit Greece from the UK
Greece is the UK's most beloved summer destination. Peak season runs June to August when temperatures reach 28°C to 38°C and the Aegean is at its most inviting. Shoulder season (May and September to October) offers warm weather between 22°C and 28°C with fewer crowds and lower flight prices from UK airports. Athens is enjoyable year-round for sightseeing. Crete and Rhodes stay warm into October. The Greek school holiday months of July and August see the heaviest tourist volumes and highest prices.

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.
