eSIM Travel Tips for Korea
K-pop, K-beauty, and street food: live data is essential
South Korea's Seoul is driven by digital culture. Naver Maps (the dominant navigation app over Google in Korea), Kakao T for taxis, and food delivery apps all need live data. Your HelloRoam eSIM keeps these working from the moment you arrive at Incheon.
Download Naver Maps or Kakao Maps before landing
Google Maps has limited functionality in South Korea due to national map data restrictions. Download Naver Maps or Kakao Maps before arrival. Both work very well on a HelloRoam local data connection throughout South Korea.
Seoul Metro is fast and easy with live data
Seoul's metro is one of the best in the world. The Kakao Metro app and NAVER Map subway planner both run perfectly on HelloRoam. Navigate Seoul's vast metro network from the moment you land.
Jeju Island has excellent coverage
Jeju Island is South Korea's most popular domestic and international tourist destination. Coverage is strong across the whole island including the Hallasan volcano hiking trails and the Olle walking routes.
NZ-Korea connections are growing
Direct Auckland to Seoul flights and the growing NZ K-culture community mean more NZ travellers visiting Korea every year. HelloRoam plans for Korea start from NZ$5.99, and on a long trip an eSIM usually costs far less than roaming day passes.

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.

Transparency Notice
- Service Provider Name (SPN)
- That's HelloRoam you see up in your phone's status bar, not a mystery reseller name. The SPN is a standard field baked into every eSIM profile, and most travel eSIM resellers do not bother provisioning their own.
- Public Network Name (PNN)
- The PNN is the network name field in your eSIM profile, set out in 3GPP TS 31.102 (EF_PNN). Your phone can read it to show the name of the network you're connected to.
- Access Point Name (APN)
- Your HelloRoam eSIM sets its own Access Point Name automatically when it installs, so your mobile connects to a local partner network without you touching a single setting.
What you see is our standard retail pricing across 185+ countries, nothing marked up for the page you landed on. The recommended plan is picked by data size and price. You can get a refund on unactivated eSIMs within 180 days.
