Does the eSIM connect the moment I reach Dublin Airport?

Yes. If you install your Yeohaengyusim eSIM before departure Korea, it links up automatically with the Three Ireland or Vodafone Ireland network as soon as you land at Dublin Airport. You don't need to look for airport Wi-Fi or wander around looking for a SIM shop.

Does the internet work well in the Irish countryside and on the west coast?

Three Ireland and Vodafone Ireland provide 97% nationwide coverage, so you can generally use it reliably not only in cities such as Dublin, Cork and Galway but also on the west coast, at places such as the Ring of Kerry, the Cliffs of Moher and the Aran Islands. However, the signal may occasionally be weak in very remote mountain areas.

Many people combine Ireland with a trip to the United Kingdom. Do I need to get a separate eSIM?

Yes. Ireland and the United Kingdom are separate countries, so you need an eSIM for each. Yeohaengyusim offers both Ireland-only plans and multi-country Europe plans, so compare them and choose the one that suits your itinerary. If you are spending a long time in the United Kingdom, a Europe-wide plan may be more economical.

Do I really need a power adapter in Ireland?

Yes. Ireland uses Type G outlets (three-pin plugs), which are different from Korea's. Korean plugs cannot go straight in, so be sure to pack a Type G multi-adapter before departure. You can easily get one at the Incheon Airport duty-free shops or from online shops.

Which season suits a trip to Ireland?

May–September is the best time to travel in Ireland. June–August in particular, with long days and mild temperatures of 15–20°C, is ideal for outdoor activities and road trips. Going to enjoy the St Patrick's Day festival in mid-March can also be a special experience. However, Irish weather is famously changeable, so a thin waterproof jacket is a must whatever the season.

Does eSIM work in Ireland?

Ireland 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 Ireland?

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 Ireland eSIM use?

In Ireland it connects automatically to local carrier networks such as Three Ireland · Vodafone Ireland · Eir (4G/LTE, 5G where supported). Population coverage is about 97%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Ireland?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Ireland 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 Ireland?

Yes. In Ireland 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 Ireland. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Emerald meadows, majestic cliffs and a cosy pub culture—Ireland is a country you are sure to come back to once you have been. Walking Dublin's lively streets and then feeling the Atlantic wind on the Cliffs of Moher is an experience nothing else can replace. But as you travel all over Ireland, Google Maps, checking your accommodation bookings and transport information all need live internet. You don't need to wander around airport shops looking for a local SIM: if you install a Yeohaengyusim eSIM in Korea in advance, you are connected right after landing at Dublin Airport. Enjoy Ireland even more freely with uninterrupted internet, whether in the narrow lanes of Galway or on the Ring of Kerry driving route.

Why an eSIM really helps for a trip to Ireland

Once you leave the capital, Dublin, Ireland is a string of small towns and country villages set in vast open countryside. When you drive along the west coast in a rental car or travel between villages by bus, you can very easily get lost without a live map app and route guidance. Ireland has 4G/LTE and 5G networks, led by Three Ireland and Vodafone Ireland, that boast 97% nationwide coverage, so you can expect a fairly stable signal even on remote stretches of coast. But buying a SIM card in the arrivals hall means long queues, and comparing plans in English is a hassle too. A Yeohaengyusim eSIM installs in under 5 minutes before departure, through the app or with a QR code. You keep your existing Korean SIM and use Irish data at the same time, so there is no worry about missing calls from your family or work in Korea. If you want to post your Cliffs of Moher sunset photos to Instagram straight away, an eSIM is the fastest way.
