The data worked well, but the best part was having a Korean 010 number. It helped with pop-up store reservations, queue systems, and a few delivery apps. The airport activation process was simple and the staff were friendly.

The counter was easy to find and the staff helped with the setup step by step. I received the T-money card benefit with my plan, which made transportation easier. The connection stayed dependable in Seoul, Suwon, and nearby areas.

Picked this up for my Korea trip and the setup was very smooth. The airport staff helped me activate it quickly, and the data worked well around Seoul, Incheon, and on the subway. Having the 010 number was useful for restaurant waiting lists and local reservations.

空港カウンターでスタッフの方が丁寧に設定を手伝ってくれました。ソウル市内や地下鉄でも通信が安定していて、地図アプリや翻訳アプリを問題なく使えました。010番号も予約時に便利でした。

長めの滞在でしたが、通信速度も安定していて安心でした。010番号があるので現地サービスの利用もしやすく、空港での設定もスムーズでした。

安裝方式清楚,掃描QR code後幾分鐘就能使用。這幾天用來查地圖、翻譯和傳訊息都很順,室內商場也能正常連線。

This was my first time using an eSIM overseas and it was easier than expected. The signal was strong in hotels, cafes, shopping streets, and underground stations. The Korean phone number helped when making bookings that required SMS verification.

The staff is incredibly friendly and helpful, making the phone connection a breeze. The connection in Seoul Jeju and Busan is excellent. I also got the Tmoney Card.

Redemption was also easy, taking only about five minutes of my time. The counter can be easily found right out of the arrival hall in Terminal 1 at Incheon International Airport. The staff was friendly, and the process was almost seamless. Although the price can be on the steeper side, it does provide you with a Korean phone number, which is important for taxis or reservations.

Received the QR codes almost immediately after our purchase. It was super easy to install and activate. The network speed is really good in both Busan and Seoul. I will definitely repurchase!

I had no trouble using the data on seoul, incheon and busan. even on the subways the signal didnt get lost!

这次在首尔和釜山都使用了这张eSIM,导航和上传照片都很顺畅。领取和开通流程简单,不需要一直找公共Wi-Fi,整体体验很好。

eSIMの利用は初めてでしたが、案内がわかりやすく安心して使えました。カフェやホテル、駅でも通信が安定していて、旅行中ずっと役立ちました。

在首爾、釜山移動時網路都很穩定,照片上傳和導航沒有問題。整體流程比買實體SIM卡方便很多,適合第一次到韓國旅行的人。

到机场后在LG U+柜台办理很快,工作人员帮我确认设置后就能上网了。在首尔、仁川和地铁里信号都比较稳定,010号码对餐厅预约也很有用。

This eSIM made the trip easier because I could use Naver Map, taxi apps, and restaurant reservation systems without trouble. The setup at the LG U+ counter was fast and the connection was reliable in both indoor and outdoor places.

I used this eSIM in Seoul, Busan, and during train rides between cities. The connection stayed stable most of the time and speeds were good for maps, messages, and uploading photos. Installation was simple once I scanned the QR code.

I activated it right after arriving and it connected within a few minutes. The data speed was fast enough for navigation, video calls, and sharing hotspot with my travel partner. I would buy it again for another Korea trip.

I saved the voucher before my flight and activated it as soon as I arrived. Everything worked immediately, including mobile data and local number service. It made traveling much less stressful because I could use maps and messaging from the airport.

Precautions

Must Read Before Use

  • Do not delete your eSIM after installation. Once removed, it cannot be reinstalled.
  • Refunds are not available once the eSIM has been issued or activated.
  • Do not scan the QR code multiple times. The eSIM can only be installed once per device.
    If installation fails, please contact support before retrying.
  • For personal use only. Commercial use, spam, or abnormal usage may result in service restrictions.

Device & Installation

  • Only eSIM-compatible and carrier-unlocked devices are supported.
  • Device compatibility may vary by model and region.
    Some devices (e.g., Google Pixel, OPPO) may not be supported on the LG U+ network.
  • An internet connection is required for installation. (Airport Wi-Fi is available)

Phone Number

  • A Korean phone number (010) will be assigned.
  • Incoming calls and SMS are available after completing identity verification upon arrival in Korea.
  • Outgoing calls and SMS require additional balance top-up.
  • This number cannot be used for Korean mobile identity verification (e.g., online services or banking).

Before You Buy

Make sure your device is compatible and understand how eSIM works before purchasing.

Here are the key things you should know.

Can I install multiple eSIMs on one device?

Depending on the device, multiple eSIM profiles may be stored.

However, the number of eSIMs that can be active at the same time may be limited by the device policy.

Our eSIM is intended for one purchase, one device, and one installation.

What should I do if the eSIM does not work after installation?

① Please check that you are currently in Korea and connected to the LG U+ network.

② Turn airplane mode on and off.

③ Restart your device.

④ Reset your network settings and try reconnecting.

If the issue continues, please contact support@lguplussim.com.

Can I use my existing SIM card together after installing the eSIM?

Yes, if your device supports Dual SIM with an eSIM and a physical SIM card, you can use both lines at the same time.

However, Dual SIM support may vary by device model, so please check your device specifications.

What should I do if my eSIM cannot be installed?

① Please check that your device is connected to the internet.

② Please check that your device supports eSIM.

③ Please make sure you are scanning the correct QR code.

If the issue continues, please contact support@lguplussim.com.

Can I reinstall my eSIM after deleting it?

No. Once an eSIM has been installed and activated, it cannot be reinstalled on the same device or transferred to another device.

Please be careful before installation, as scanning the QR code multiple times or attempting repeated installation may cause the eSIM to expire.
