The eSIM must be installed and activated at the destination within 30 days of ordering, otherwise it will become invalid and cannot be used.
An Internet connection is required to install the eSIM. Please make sure there is available WiFi or mobile data before installation.
Please remember to turn off data roaming on the original SIM card to avoid using the mobile network of the original SIM card and incurring high roaming charges.
When you finish using the eSIM plan in your phone, click [Remove Action Plan] at the bottom to remove it.
Please be aware that the quality of Internet access may be affected by factors such as location, terrain, building shielding, number of users and weather.

If you experience connectivity issues with your Korean eSIM card, first ensure your device's mobile data is enabled and the eSIM profile is selected for data usage. Try toggling airplane mode on and off, or restarting your phone. Verify that data roaming is activated for your eSIM. If issues persist, manually select the network operator in your phone's settings, choosing a major Korean carrier like SK Telecom, KT, or LG U+.
A Korean eSIM card might experience no network connection due to several common reasons. These include incorrect APN settings, the eSIM profile being disabled or not set as the primary data line, data roaming being turned off, or the device not being eSIM compatible. Additionally, poor signal strength in specific indoor or remote locations, or a temporary network outage, could also be contributing factors.
A Korean eSIM card generally offers excellent 4G performance and wide network coverage throughout South Korea. Users can expect fast and smooth internet access in major cities like Seoul and Busan, as well as popular tourist destinations. While coverage is robust, performance might vary slightly in very remote mountainous regions, underground areas, or inside some older buildings.
When using a Korean eSIM, users should be aware of a few potential challenges. Device compatibility is crucial, as not all smartphones, especially older models or certain regional Samsung versions (like those from Taiwan), support eSIM functionality. Ensuring data roaming is correctly enabled for the eSIM profile is a common oversight. Also, temporary network congestion in very crowded areas might occasionally affect speeds, but this is generally rare.
Activating your Korean eSIM card is straightforward. After receiving your QR code, go to your phone's settings, then to 'Cellular' or 'Mobile Data,' and select 'Add Cellular Plan.' Scan the provided QR code, and follow the on-screen prompts to install the eSIM profile. Once installed, ensure the new eSIM is set as your primary line for mobile data and that data roaming is enabled for it to connect to local networks.
The 4G signal stability of a Korean eSIM card is highly reliable. In urban centers, connectivity is consistently strong, providing fast speeds for all data needs. While generally stable, signal strength might naturally decrease in very isolated rural areas or within deep valleys and tunnels. However, for most travel itineraries covering cities and popular attractions, stable 4G internet access is consistently available.
Korean eSIM cards typically offer a variety of daily high-speed data plans, often with unlimited usage. These plans are designed to provide seamless internet access for various user needs, from navigating with maps and communicating via messaging apps to browsing and streaming. The flexibility of these plans ensures a hassle-free user experience without the worry of running out of data during your trip.
Korean eSIM cards are compatible with most recent Apple iPhones (iPhone XR and newer) and a wide range of Android smartphones. For Android devices, key brands like Google Pixel (Pixel 3 and newer) and many Samsung Galaxy models support eSIM. However, it's crucial to note that Samsung phones purchased in specific regions, such as Taiwan, do not support eSIM functionality, so always confirm your device's compatibility before purchasing.
