Purchase Notice
- 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
- Telecommunications companies adhere to the principle of fair use of Internet communications in order to maintain network quality. Large amounts of Internet traffic are regulated in a short period of time, which may result in Internet access failure or slow Internet speed.
- Users with abnormal traffic will be restricted (2~5GB per day may trigger this standard), which may result in Internet access failure or slow Internet speed.
- Detailed traffic calculation is based on the data provided by the telecom operator. To avoid violating the principle of fair use, it is recommended that if you need to use large amounts of network traffic, you should do so in a wifi environment. Please refer to the following:
- Large-scale file transfer (upload/download), video watching, live broadcast, mobile game playing, social software mainly consists of videos and photos, and using it to a certain extent is equivalent to watching a lot of videos
- It is also recommended to turn off the automatic update and backup functions, the social software automatic play function, the satellite map navigation mode (you can use the normal mode navigation) and the cloud hard drive data transfer function.

Reminders
Please activate your eSIM within 90 days of receiving it.
Before installing the eSIM, please make sure you are connected to WiFi or mobile network to scan the QR Code or enter manually to join the mobile plan.
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.
The usage period of the eSIM starts after installation. If you are taking a long-distance overnight flight, it is recommended to purchase an extra day of usage. You can install the eSIM before boarding the flight to get the best usage experience.
A QR code can only be scanned once with one mobile phone and cannot be changed after binding
Please delete the description file on iPhone (check steps: Settings -> General -> Device Management, scroll to the bottom, if there is no description file, it means it is normal) to avoid problems with smooth use.
If the eSIM plan is not fully used or the plan is deleted without the approval of DJB customer service staff, no reissue or refund will be made.
Days calculation method: Assuming the card is activated at 09:00 on the 1st, the first day ends at 23:59 on the 1st (based on GMT+9 time zone); the card will expire at 12:00 on the selected day, and the time calculation is based on local time
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.
Guaranteed no speed reduction plan: If there is malicious use of the network (such as using more than 10GB of bandwidth in a short period of time or maliciously sending packets, etc.), the telecommunications operator has the right to terminate the user's service.
The Fair Usage Policy is a regulation implemented by governments and telecommunications companies to protect the rights of local users to use the Internet. If you have concerns about FUP control, please purchase a plan with a fixed daily traffic.
