Unfortunately, this SK Telecom eSIM card allows for receiving calls but does NOT allow for making calls (receiving calls is OK though).

iPhone12 Pro Max (from AT&T, unlocked) The eSim was extremely easy to use as a data sim. I had the eSim QR code ready on a secondary device. When I arrived at Gimpo Airport 1) I immediately connected to the free Airport Wifi 2) went to the Cellular setting 3) Clicked the add eSim and by QR code 4) Scanned the QR code from my secondary device 5) Waited a few minutes for the phone to connect to the network (you may need to reset your phone but I didn’t have to) 6) I ensured that cellular data switching was off and that the new eSim was set as the primary data network, so it wouldn’t use my US phone line in the “Cellular Data” setting 7) enjoyed using the unlimited data! I was able to use the phone number provided with the QR code in the K-ETA and the Q-Code webpage. I did receive some random text messages with Bible versus, but I just ignored them. 10/10 would purchase again.

R**** 2023-04-18 66 5points

So worth it!

Great purchase! Easy to figure out, didn't lose signal once throughout my stay in Korea, and speed was fast

한국에 한달동안 머물게 되어 이 웹사이트에서 유심칩을 구매했습니다. 첫날에 활성화를 했을때 살짝 문제가 있었지만 페이스북 메신저로 문의 드렸더니 엄청 빨리 답장도 주시고 문제도 빨리 해결해드렸습니다. 현재 2주정도 사용중인데 별문제 없었고 속도도 괜찮습니다. 좀 아쉬운게 있다면 한국에서 개통한게 아니여서 온라인으로 본인인증은 안되더라고요.. 그거빼곤 만족합니다!!

里**** 2023-01-25 58 5points

i accidentally purchased 2 quantities of 1-day Korea eSIM Red and i only need one (yes, i am that stupid. *note: the site already gave me heads up that i was purchasing the same product 2 times and asked me if i still want to continue but i absentmindedly tapped yes because i was panicking*) i immediately messaged the customer service for a possible refund and still got no reply but because the sim that i bought from the airport is about to expire, i decided to read once again the precautions of this site and saw that refunds are impossible (unless they considered your case carefully just like that one review here) but then thankfully, the  qr codes that were sent to me (they sent it in a flash btw, everything was so fast) were two different qr codes (as it should be because i bought 2 quantities after all)  so  ! i just decided to keep the other one for my next trip here in south korea because it can still be activated 1 year after you receive the qr code. to add, the eSIM is working well! its my first time using an eSIM and my cellular network went from KT to SKT. the signal is good and is just as fast as the other physical sim that i bought from the airport. 

i will surely purchase from this site again because aside from the fast transaction, its very affordable too! thank you so much krsim!!

t**** 2022-12-31 69 5points

Due to my fault, I was not able to use eSim at all. According to the policy, I gave up to get refund. However, the company carefully considered my situation and made an exception. This company offered the best price, fast response and reasonable refund service. 

Definitely, I will love to use whenever I am visiting Korea!
