eSIM Travel Tips for Korea
Sort your data before your flight from Dublin
Buy your HelloRoam eSIM for South Korea at home, activate it over Wi-Fi, and enable data when you land at Incheon International Airport. You skip the long SIM card queues at the airport and step off the plane already on Korean 5G.
Keep your Irish number active
On a dual SIM phone, keep your Eir, Three IE, or Vodafone IE SIM for calls and texts while using HelloRoam for data in South Korea. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks
Download Google Maps for Seoul and Busan offline before you go. South Korea is very well covered in all major cities. Remote mountain areas like Seoraksan National Park can have weaker signal in places.
Travel insurance and emergency numbers
Keep your travel insurance details handy. In South Korea, dial 112 for police and 119 for fire and ambulance. Save these before you fly. Your HelloRoam eSIM keeps your health insurance app, the Irish embassy in Seoul, and translation tools accessible throughout your trip.
Currency and card acceptance
Notify your Irish bank before travelling to South Korea. Card acceptance is generally good in Seoul but carry some local currency for smaller vendors and public transport. Currency conversion apps work well on a HelloRoam data connection.
Mobile networks in South Korea: what Irish visitors need to know
HelloRoam connects on LG U+ and SK Telecom in South Korea. Both offer extensive 5G coverage across Seoul, Busan, and major cities, with 4G reaching rural areas and Jeju Island. Coverage and speed depend on the local network where you are.

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.
