eSIM / 2025-06-30
I’m visiting Korea with our kids and needed
both data and calls. Ordering the eSIM in
advance was so easy—they sent the QR code
right away and setup was smooth.
I plan to share the unlimited data with my kids
using tethering, which is a big help.
I’m using it for 20 days, and the price is
incredibly reasonable. The 10 minutes of free
calling is also a nice bonus.
Now all that’s left is to enjoy our trip to Korea
with peace of mind. Thank you so much!

Since my business schedule was a bit unusual,
I ordered both a 2-day and a 6-day eSIM to
match my travel plans. I received the QR codes
and setup guides right away by email.
I installed the 2-day eSIM before leaving the
U.S., and as soon as I landed at Incheon
Airport, I activated it and was instantly
connected.
I’m planning to use the second eSIM on my
return to Korea, and I’m confident it’ll work just
as well.

다음 달 초 한국 방문 예정이라 미리 심카드를
주문했는데, 바로 QR코드를 보내줘서 미리
설치까지 완료했습니다.
미국 시민권자는 한국전화번호 사용은 온라인
여권 확인을 통해 가능하다는 안내 이메일까지
보내주어서, 한국 도착 후 이동하면서 온라인
인증을 진행해보려고 합니다.
예전에 어떤 회사는 여권 사본을 따로
보내달라고 해서 꺼림칙했던 기억이 있었는데,
Y Connect Korea는 그런 요청 없이 제가 직접
안전하게 온라인에서 인증을 진행할 수 있어
너무 좋네요.
한국가서 사용해보고 데이터 속도까지 빠르면
주변에도 꼭 추천할게요!

eSIM 설치가 어려울 것 같아 고민했는데 주문 후 바로 큐알코드와 설치 이메일을 보내주셔서 너무 쉽게 설치했어요.
저는 한국에서 통화가 필요해서 공항에 들려 전화번호를 개통했어요. 하지만 충전은 인터넷으로 직접 하라고 안내서를 주더라고요.
바로 이동하면서 충전 페이지에 접속해서 충전해 사용했어요. 어려운 것은 없었고 가격도 한국보다 더 싼 것 같아요.
인터넷 속도는 SK라서 그런지 빠르네요. 앞으로 한국 갈 때마다 이용하겠습니다. 강추입니다.

I activated the eSIM after arriving at my aunt's house in Korea because I was too busy. Of course, there was no problem.
And I verified my passport and recharged separately on different online sites according to the installation guide email.
These tasks were not difficult either. But it would be better if I could verify my passport and recharge on the same site.
Everything else was good. Thank you I had a wonderful trip to Korea.

The e-SIM worked amazingly throughout my 7-day trip to Korea, providing me with fast and reliable internet to access the map, social media, and streaming videos!
I am always pleased with the ease of service and the quality, so I will definitely be ordering again when I need data in Korea!
