The validity period of eSIM is 180 days, starting from the first day of ordering. Please use it within the validity period. No refund or extension will be available if the expiration date is exceeded.
Before installing the eSIM, please make sure you are connected to a WiFi or mobile network that can access the Internet, then scan the QR Code to join the mobile plan.
eSIM can be installed in Taiwan first, and then activated at the destination. If the network is used up in advance due to activation in Taiwan, no refund will be given.
Days calculation method: After arriving at the tourist destination and turning on data roaming and connecting to the Internet, the day is calculated based on the Taiwan time calendar system. One day is counted after midnight Taiwan time (GMT+8), not the 24-hour system.
A QR code can only be scanned once with one mobile phone. It cannot be changed after binding. If there is a prompt to contact the telecom operator or other prompts, please turn off and restart the phone or contact customer service.
Please save this QR Code. Once scanned, it will become invalid and cannot be reissued. Please follow the instructions to install it. Do not exit the screen during the process to avoid the phone misjudging and causing the eSIM plan to be deleted or wrong.
Hotspot sharing will occupy bandwidth, and the network speed will vary depending on the terminal device and geographical location, so the minimum network speed is not guaranteed. Please confirm before placing an order
The quality of telecommunications networks in different countries varies. The base station construction is not as dense as that in Taiwan. The regionality and telecommunications construction of each country are different. We are sorry that we cannot request a refund due to the signal conditions in a few areas.
The actual signal and connection speed of this card will vary due to factors such as region, terrain, climate, building shielding, number of users, network system or terminal equipment. If the local area or mobile phone cannot support 5G network, it will automatically switch to 4G/3G signal.
In addition, if the network is unstable, disconnected or unusable due to force majeure events such as earthquakes, typhoons, etc., you cannot request a return or exchange.
It is not recommended to transfer large amounts of files (upload/download), watch videos, (watch) live broadcasts, play mobile games, etc.; it is also recommended to turn off the automatic update and backup function, the automatic play function of social software, the satellite map navigation mode (normal mode navigation can be used), and the cloud hard drive data transfer function.
According to the principle of fair use of the Internet, telecommunications companies may, at their discretion, restrict the data usage of users who use a large amount of data traffic in a short period of time. Please avoid watching online videos for a long time or using a large amount of data traffic in a short period of time.
For eSIM operation problems, please contact the supplier's technical customer service (see the order notes for contact information) and provide the KKday order number to quickly obtain dedicated assistance.
