Reminders
Before installing eSIM, please make sure to connect to WiFi or mobile network to scan the QR Code or enter it manually to add the action plan. (After the iPhone is updated to iOS 17, you can directly click "Open Photos" to scan the picture QRCode in the phone to install it)
Please install according to the instructions. Do not jump out of the screen during the process to avoid misjudgment by the phone and causing the eSIM plan to be deleted.
A QRcode can only be scanned once with one mobile phone and cannot be replaced after binding.
If an error message is displayed after scanning, it does not mean that esim is invalid. Please restart your phone and go to the mobile service page to check whether esim has been bound to your phone, or contact customer service for assistance. Do not scan other QRCodes without authorization to cause repeated binding and cause esim to become invalid.
The eSIM can be reserved for up to 180 days before scanning. Once scanned, it must be activated within 30 days; if not activated within this period, it will automatically expire and cannot be refunded or extended.
For iPhone, please delete the description file (check steps: Settings -> General -> Device Management, scroll to the bottom, if there is no description file, it means it is normal) to avoid being unable to use it smoothly.
If the eSIM plan is not fully used or the plan is deleted without the judgment of customer service staff, reissue and refund will not be possible.
The day you scan the QRCode is considered the first day of use. It is recommended to scan the code and install it before taking off or after arriving at the destination to avoid activating it in advance and affecting your use rights. After 0:00 midnight Taiwan time (GMT+8), it is a day, not 24 Hourly time.
The quality of telecommunications networks in different countries varies, and the base station construction is not as dense as in Taiwan. The region and telecommunications construction of each country are different. Refunds cannot be requested due to signal conditions in a few areas. If you encounter poor signal, you can manually switch telecom providers. Telecommunications provider switching method: Network selection/Telecom provider>Automatic shutdown>After searching, there will be different telecom providers to choose from.
If it cannot be used when you arrive at your destination, please contact line customer service. After-sales service cannot be handled after returning to your country.
