LG U+ is one of South Korea’s "Big 3" premium network providers, known for its world-class 5G infrastructure and ultra-wide coverage. Choosing a native LG U+ eSIM is essential for travelers for three reasons:
Native 5G Speed & Low Latency: Unlike roaming SIMs that route data through third-party countries, ByteSIM’s LG U+ eSIM provides a native connection. This means instant loading for Google Maps, seamless 4K streaming, and zero lag for social media uploads.
99% Nationwide Coverage: From the bustling streets of Myeong-dong (Seoul) to the volcanic landscapes of Jeju Island, LG U+ ensures you stay connected even in subways, high-speed trains (KTX), and rural mountainous areas.
Reliability for Digital Nomads: With the highest 5G availability in urban centers, it is the most stable choice for remote work, video calls, and essential travel apps like KakaoTalk and Naver Map.
Your data plan activates only when you arrive in South Korea and connect to the LG U+ network.
Install Early, Activate on Arrival: You can safely scan your QR code and install the eSIM while still at home or at the airport. The validity period (e.g., 5 days or 10 days) will not start until your phone successfully registers on a local Korean tower.
Pro Tip: We recommend installing the eSIM a day before your departure so you can enjoy instant 5G connectivity the moment you touch down at Incheon or Gimpo Airport.
Yes, it is 100% truly unlimited. Unlike many other travel eSIMs that throttle your speed after a daily limit, ByteSIM’s South Korea LG U+ plan features No Fair Usage Policy (FUP) and No Speed Reduction.
Permanent 5G High-Speed: You will enjoy unrestricted 5G ultra-fast speeds from the first minute to the last second of your plan.
No Throttling: Whether you use 10GB or 100GB in a single day, your connection will never slow down.
Freedom to Stream & Share: Perfect for high-definition 4K streaming, heavy social media uploading, and professional video conferencing without ever worrying about data caps.
Yes. Since this is a native LG U+ product, you will be assigned a local South Korean IP address.
Lower Latency: Data doesn't need to be routed through a third country, ensuring the lowest possible lag for gaming and video calls.
App Compatibility: You will have full, unrestricted access to local South Korean apps and services (like Naver, Kakao, and local banking) that may require a domestic IP.
Absolutely Yes! You can share your unlimited 5G connection with multiple devices via Hotspot/Tethering.
No Limits: Since this plan has No FUP (No speed reduction), you can connect your laptop, tablet, or friends' phones without ever worrying about the speed dropping.
Stay Fast Together: Perfect for group travel or remote work, ensuring everyone enjoys high-speed 5G simultaneously.
By default, this is a Data-only eSIM. It does not support traditional voice calls or SMS.
Need a Phone Number? If you require a local number for calls/SMS, you can complete identity verification at LG U+ counters in Incheon (T1/T2) or Gimhae Airport.
Coming Soon: We are excited to announce that Online Verification will be launched very soon, allowing you to unlock voice and SMS features directly from your phone!
💡 Pro-tip: For most travelers, we recommend using data-based apps like KakaoTalk, WhatsApp, or FaceTime for seamless communication.
If your eSIM order hasn't been activated, you are eligible for a full refund. Additionally, if you experience no service upon arrival and replacing the QR code doesn't resolve the issue, you are also entitled to a refund. Please contact our customer support for assistance.
No, top-ups are not supported. If you need more data or days, please purchase a new eSIM. Your new QR code will be delivered to your email in just 5-10 minutes!
You can check the real-time 5G/4G coverage on the official LG U+ map. LG U+ provides 99% nationwide coverage, ensuring a stable connection even in subways and rural areas.
