eSIM Travel Tips for Korea
Install your eSIM before your India-Korea flight
Flights from India to Seoul take 7 to 9 hours. Install your HelloRoam eSIM at home before departure. Enable data at Incheon Airport and you are instantly connected for Kakao Maps, Naver Maps, and subway navigation.
Download Naver Maps or Kakao Maps before arrival
Google Maps has limited routing information in Korea due to local regulations. Naver Maps and Kakao Maps are the local alternatives and work much better for navigating Seoul's subway, buses, and walking routes. Download them with your HelloRoam data after landing.
Keep your Indian SIM for family calls
Keep your Jio or Airtel SIM active in slot 2 for calls from India. Use HelloRoam as the data line for Korea. This dual setup means you stay reachable on your Indian number while using Korean 5G data for navigation and K-pop streaming.
Korea's subway system needs good data
Seoul Metro is extensive and very well connected. Kakao Maps real-time subway updates and T-money card apps need consistent data. HelloRoam's 5G connection makes navigating Seoul's transit system straightforward.
Coverage is exceptional even underground
Korea has 4G and 5G in subway tunnels across Seoul. Your data works underground on the Seoul Metro, unlike many other cities. No need to download routes offline before entering the subway.
Mobile networks in South Korea: what Indian visitors need to know
South Korea has three main carriers: SK Telecom, KT Corp, and LG U+. HelloRoam connects on LG U+ and SK Telecom. Both provide 5G across all major cities, with strong urban and indoor coverage. Your eSIM automatically selects the best signal available.

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.
