No issue with this eSIM. Easy to install and coverage is generally good. Slower connection only occasionally in some subway rides.

When I was planning my trip to Seoul, one of my biggest worries was staying connected. I needed to be able to navigate (Naver Map), share my adventures on social media, and keep in touch with family without a hitch. I decided to try the Hello 1010 eSIM, opting for the 15-day, 10GB plan, and it was seriously one of the best decisions I made for my trip. Easy to install too, just scan the QR code emaled by them, after payment of course. Not to mention their help line (Whatsapp) is fenomenal, readily available and super helpful, like The FLASH.
The price was an absolute steal, making it incredibly affordable for my budget. What truly blew me away was the data! I was snapping pictures and uploading videos almost non-stop, sharing every amazing moment on my social media feeds, every day. After a day of heavy use, I was amazed to find I still had a ton of data left. It felt limitless!
Beyond the generous data, the connection was an absolute dream. It was incredibly smooth and, most importantly, never failed, not even once. Whether I was exploring the bustling streets of Seoul or the serene, picturesque landscapes of Jeju Island, my connection was rock solid. No more frustrating buffering or lost signals at the worst possible moments. In a subway, while in JuseongJolidae, well, basically any where in Jeju and Seoul, connection is awesome!
The Hello 1010 eSIM truly was the silent hero of my trip. It gave me the freedom to explore without a single worry about connectivity. I can't recommend it enough for anyone traveling to Korea. It's affordable, reliable, and gives you the peace of mind to focus on making incredible memories.

The overall service of Hello 1010’s eSIM is excellent. There has never been any issue with dropped connections. However, I would suggest making the process of using the eSIM simpler, as older individuals like me tend to get confused during the installation process.
