Purchase Notice
- Please ensure you activate the eSIM within 30 days of receipt.
- The eSIM QR code can only be scanned once. If you receive a prompt to contact your carrier or other error messages, please restart your phone or contact technical support.
- Day calculation: The first day starts upon activating the eSIM in the destination country and ends at 23:59 on that same day. The card will expire at 12:00 AM on the final day of your selected duration (based on Taiwan time).
- Please turn off the eSIM number after scanning and binding at the Taiwan airport on the day of departure. Turn it back on only after landing to avoid time zone discrepancies. Time calculations are based on Taiwan time. Please set up the eSIM on the day of departure; if the QR code expires due to early scanning, it is considered a personal error and cannot be reissued or refunded.
- Before installing the eSIM, please ensure you are connected to Wi-Fi or mobile data, then scan the QR code to add the mobile plan.
- Please keep this QR code safe. It will become invalid once scanned and cannot be reissued. Please follow the installation instructions and do not exit the screen during the process to prevent the phone from misidentifying the eSIM, which could lead to the plan being deleted.
- To maintain network quality, telecommunications companies adhere to a Fair Usage Policy (FUP). High data usage in a short period may trigger automatic restrictions, potentially resulting in loss of internet access or slower speeds. If you are throttled due to FUP, please contact technical support.
- Network performance varies based on user traffic, weather, building obstruction, and location. If you experience unstable signal, please contact technical support.
- Network quality varies by country and base station density is not as high as in Taiwan. Differences in local geography and infrastructure exist, and we cannot offer refunds based on signal conditions in specific areas.
Includes/Excludes
