    FAQ

    The main difference lies in the amount of data available and the speed limits.

    Unlimited Plan: The Unlimited Plan for Korea eSIM, using the “LG U+” network, offers high-speed data (maximum speed) up to about 3 GB per day. After that, under the FUP (Fair Usage Policy), the speed is limited to a maximum of 5 Mbps※, but you can continue using data without extra charges. The speed limit resets daily at 12:00 AM GMT+9. Additionally, the Global Mobile Korea 4G/5G Unlimited Plan includes a phone number that can receive SMS and calls.

    ※FUP (Fair Usage Policy) is a usage restriction that ensures all users can access the network fairly. A 5 Mbps speed is sufficient for normal usage such as map apps, social media, and HD video streaming.

    Data Plan: You choose the data amount and number of days at purchase. It’s flexible based on your usage needs and schedule, but once you use up the data, you cannot add more or recharge — it requires purchasing a new eSIM.

    The best Korea eSIM plan for your trip depends on your usage style. If you mainly use Wi-Fi in your hotel and only need light use while out, such as for social media, messaging apps, and Google Maps, a Data Plan matched to your travel days (e.g., 3GB/day) is sufficient.

    However, if you want to enjoy video streaming or video calls without worrying about data usage, the Unlimited Plan is recommended. The Unlimited Plan has a daily high-speed limit of about 3 GB, after which you can continue at up to 5 Mbps, and it also includes a phone number—convenient for making reservations or receiving calls from popular restaurants and shops. Since travelers often consume more data than expected, choosing the Unlimited Plan is a safe option if you’re unsure.

    We recommend installing it in your own country before departure. You can load (install) the eSIM profile before leaving your country. However, you should only activate the line (switch mobile data to the eSIM) after arriving in Korea. Keep the eSIM line off until you arrive, then turn it on to start using it smoothly. As activation requires a stable Wi-Fi connection, it’s best to complete setup using home or airport Wi-Fi before your flight. The usage period starts when you begin using mobile data in Korea. Even if you install it in advance in your own country, it will not connect to the Korea network until you arrive, so the count will not start until then.

    The Korea 4G/5G Unlimited Plan using LG U+ includes a phone number that can receive SMS and calls, allowing you to receive local communications while in Korea. ※The number is assigned after arrival in Korea and cannot be used outside Korea.

    Data Plans, on the other hand, are data-only. They do not include a phone number, and calls/SMS are not available.

    First, check the following:

    Device compatibility: Ensure your smartphone supports eSIM and is SIM-unlocked. If it’s not compatible, scanning the QR code won’t add the plan.

    QR code scanning: Make sure the smartphone camera fully captures the QR code. If brightness or focus is an issue, try enlarging the code or adjusting the screen brightness.

    Network connection: Downloading the profile requires internet access, so try again in a stable network environment such as Wi-Fi.

    Mobile data settings: Check if the QR code has already been read and the eSIM added in your device settings. If it’s already added, scanning again will not work—proceed with the next setup step.

    If it still doesn’t work, you can manually enter the eSIM information using the “SM-DP+ Address” and “Activation Code” shown after purchase. Go to your device’s “Add mobile plan manually” option to set it up. Please refer to the setup manual (PDF link) for detailed instructions. If you cannot resolve the issue yourself, feel free to contact our 365-day support via Contact Us.

    Customers who purchase an LG U+ eSIM can receive various gifts such as a Tmoney card, cosmetic shop coupons, and exclusive K-pop official stickers. These can be collected at LG U+ counters located in major Korean airports such as Incheon International Airport and Gimpo Airport in Seoul, and Gimhae Airport in Busan.
