This eSIM data roaming service is provided by China Unicom.
Before purchasing, please ensure that your phone and its operating system support the eSIM function. If the order is cancelled due to device incompatibility, no refund will be given.
iOS requires the latest version. Please note that iPhones sold in mainland China do not support eSIM. In Hong Kong and Macau, only the iPhone 13 mini, iPhone 12 mini, iPhone SE 2020, 2022, and iPhone XS have eSIM functionality.
Samsung phones vary in different countries. Samsung phones purchased in Taiwan do not support eSIM. Please confirm with the Samsung official website for other regions first.
An internet connection is required to install the eSIM. Please ensure that there is WiFi or mobile data available before installation.
It is recommended that you scan and install the eSIM after arriving in Korea and connecting to the free Wi-Fi at the airport. Do not install the eSIM while in a vehicle to avoid network interruption and failure of eSIM installation.
Each QR code can only be scanned and installed once. Once bound, you cannot change the device or delete it. Once scanned and installed, no returns or refunds are available. Please note that we do not accept returns or refunds.
Please remember to turn off data roaming on the original SIM card to avoid using the original SIM card's mobile network 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.
If you encounter any problems with the network card, please contact customer service immediately. Cancellations and refunds without prior contact will not be accepted.
Please note that signal quality may be affected by factors such as location, terrain, building obstruction, number of users, and weather.
