Does data work well on islands such as Santorini and Mykonos?

Yes. The Cosmote and Vodafone Greece networks cover most of the main tourist islands, such as Santorini, Mykonos and Crete. In the villages and around the harbours of popular islands, 4G/LTE connects reliably. Please note, though, that the signal may weaken on remote beaches with hardly anyone around, or at sea near small uninhabited islands.

Can I use data when I take a ferry from Athens to the islands?

Data works well at the main departure points, such as the ports of Piraeus and Rafina. During the ferry crossing, the signal may weaken or drop the further you get from land. If you download offline maps in Google Maps in advance or save the ferry timetable as a screenshot, you can get around even more easily.

If I install a Greece eSIM, can I still receive calls and texts on my Korean number?

Of course. The Yeohaengyusim eSIM works for data only, and your existing Korean SIM stays in your device. So you can receive KakaoTalk messages, texts and calls just as usual. However, your Korean carrier may charge separately for international roaming voice calls, so it's much cheaper to make calls with KakaoTalk or WhatsApp.

Can I use Google Maps navigation with a Greece eSIM?

Yes, of course. You can use Google Maps in real time, from exploring the backstreets of central Athens to driving around the Peloponnese peninsula in a rental car. Signs in Greece are written in both Greek and English, but map apps are a big help, especially in the maze of alleys in island villages.

Are Greek sockets different from Korea's, so that I need a separate adapter?

Greece uses Type C and Type F sockets. Korea's standard plug (Type C, two round pins) fits most Greek sockets as it is, so you can often use it without a separate adapter. However, flat Korean plugs or power strips may not fit, so bringing a Type C travel adapter gives you extra peace of mind.

Does eSIM work in Greece?

Greece supports eSIM, and plans start from ₩1,492. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Greece?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Greece eSIM use?

In Greece it connects automatically to local carrier networks such as Cosmote · Vodafone Greece · Nova (formerly Wind Hellas) (4G/LTE, 5G where supported). Population coverage is about 95%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I add to or extend my Greece eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Greece?

Yes. In Greece you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Greece. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

How many GB of data do I need for a trip to Greece?

For mostly maps and messaging, we recommend about 1 GB a day; to use plenty of social media and photo uploads, about 2 GB a day. If you stream a lot of video or tether a lot, an unlimited plan is better. You can always buy more if you run short, so it is fine to choose a little extra at first.

From Santorini, where white walls and blue roofs spread across the cliffs above the Aegean Sea, to the Acropolis, where history and myth are still alive, to Mykonos, the party island—Greece is a special country that makes you want to go back once you've been. After flying about 12 hours from Korea to get there, you'll want to avoid getting lost or failing to find good places to eat. To travel between dozens of islands while checking ferry timetables, finding accommodation and looking up travel information, a stable data connection is essential. If you install a Yeohaengyusim eSIM before departure, you're connected without a hitch from the moment you set foot in Athens airport. There's no need to swap SIM cards or queue at a carrier booth at the airport. Just focus on your trip under Greece's dazzling sunshine.

Travelling in Greece: why should it be an eSIM?

The defining feature of a trip to Greece is moving between the mainland and its many islands. Ferry schedules differ for each island, such as Santorini, Mykonos, Crete and Rhodes, and there's a lot you need to check in real time, from local transport to accommodation information. In this situation, losing your data connection can throw the whole trip off. A Yeohaengyusim eSIM uses the network of Cosmote, Greece's largest carrier, to give wide coverage of about 95%, reaching not only the mainland but also the main island areas. It supports not only 4G/LTE but also 5G speeds, so you can enjoy Google Maps navigation, Instagram uploads and video calls smoothly. International roaming charges in Greece are quite high, so if you just keep using your carrier's roaming, your bill could give you a shock. With a Yeohaengyusim eSIM, everything is ready with a single QR code installation before departure. Your existing Korean SIM stays as it is, so you can still receive KakaoTalk messages and texts without any problem. Enjoy Greece to the full without worrying about data, with the Mediterranean breeze blowing through the olive trees.
