Frequently Asked Questions / FAQ

First time here? We’ve got answers for you.

1. What is an eSIM? Can I use it without a physical SIM card?

eSIM stands for embedded Subscriber Identity Module. Unlike a physical SIM card, it's built into your phone and doesn’t need to be inserted or removed.

Most new phones support eSIM.

※ iPhones sold in the U.S. from iPhone 14 and up only support eSIM.

2. Why is it good to install the eSIM in the U.S. before traveling?

You can safely install the eSIM on your phone before leaving the U.S.

※ You’re usually busy and distracted when you arrive at the airport, so it’s hard to take time to find the best SIM card for you.

3. Which smartphones support eSIM?

※ Please confirm that your phone supports eSIM through your mobile service provider or manufacturer.

How to check eSIM

4. How fast is the internet? Is it stable?

You can use unlimited LTE data at speeds up to 100Mbps, with no daily limit, anywhere in Korea.

SK Telecom’s nationwide network provides stable internet even in rural and mountain areas, so it’s easy to stay connected with your family and friends.

5. Are there any foreign exchange fees when paying for a SIM card?

No. Payment is made in US dollars (USD), so there are no currency conversion fees.

Y CONNECT KOREA offers Korea SIM cards at very competitive prices compared to other US-based providers. There are no extra fees or hidden charges, so you can order with confidence.

We help make your trip to Korea more affordable and convenient.

6. Can I use the eSIM or SIM card (airport pickup) right after arriving in Korea?

Yes, you can use it immediately.

For eSIM: You can install the eSIM on your phone before leaving the U.S. With just a few taps during your flight, your phone will be connected as soon as you land.

※ If you want to use voice/text services, visit the SKT roaming center at the airport for passport verification and charge the amount for outgoing call/texts.

For SIM card (airport pickup): Order in advance from the U.S., then show your voucher and passport at the SKT roaming center in the airport to receive your SIM card. Insert it into your phone and you're ready to go.

※ To use voice/text outgoing, please charge the amount for outgoing call/texts.

7. How long is the eSIM or SIM card (airport pickup) valid?

Both eSIM and SIM cards are valid for 1 year from the order date.

eSIM / 2025-10-18

일단 등록부터 사용까지 너무 좋았습니다. esim으로 신청하고 인천공항에서 사용하기까지 원스탑으로 편리했습니다. 사용하는 동안도 끊임 없이 잘 사용하였구요. 전화도 잘 되었습니다. 다음에도 꼭 이용하고 싶네요

First of all, the eSIM was very easy to use. The registration process was simple, and the specifications were straightforward as well. And the speed was fast, and the call quality was excellent. During the 15 days I used it, I didn’t experience any inconvenience at all. Next time we visit Korea, our family will use it again.

I really enjoyed using this service! It was easy to set up with the clear instructions. I missed the chance to verify my passport at the airport, but I was able to activate Korea number online while on the move! Super user friendly ☺️💗 So cool that Y CONNECT set this all up!!!! Actually, I was going to ask my friend who recommended Y CONNECT to me, but I wanted to experience it as a first user and navigate by myself😂 And as someone who’s not good at these things, it was very user friendly! My parents ended up setting up with V***’s roaming service, but I think it’s more costly and it doesn’t give a local phone number so I personally think Y CONNECT is the way to go!! Thank you, my friend and Y CONNECT KOREA☺️☺️ very foreigner-friendly!!!

I live in Sydney and used this eSIM for a 7-day trip to Korea. It activated automatically, and after restarting my phone, the data worked perfectly with fast speeds. I’ll use it again on my next visit. It would be great if the description made clearer that it also works for users outside the U.S.

I only need 45 days, but I ordered the 60-day plan because the price was so reasonable. The staff kindly explained through KakaoTalk how to check if my phone was unlocked and eSIM-compatible, so I was able to order with confidence and even install the eSIM before my trip. As a U.S. citizen, I also plan to use my passport for online verification once I arrive in Korea. I haven’t departed yet, but I wanted to write this review in advance to express my gratitude.

USIM(공항픽업) / 2025-09-01

저는 삼성 Z Fold 5를 사용하고 있는데, 예전에는 한국 갈 때마다 공항 편의점에서 심카드를 구매해서 사용했습니다. 이번에는 인터넷에서 가격도 더 저렴하고 속도도 빠르며, 공항 로밍센터에서 지원까지 된다고 해서 Y Connect Korea 심카드를 이용해 보게 되었습니다. 저녁에 인천공항에 도착해서 짐을 찾고 바로 로밍센터에서 심카드를 픽업해 개통했습니다. 공항을 나서 리무진 버스를 타고 이동하면서 곧바로 한국 도착 소식을 지인들에게 알릴 수 있어서 정말 좋았습니다. 한 달 가까이 머무는 동안 속도나 데이터 사용에 전혀 불편함이 없었고, 부담 없이 편리하게 사용할 수 있어 정말 만족했습니다. 다음에도 꼭 다시 이용하겠습니다.
