After placing an order with DJB, you will receive an email with the subject 'Payment Completed' and 'Order Established'.

To check your order, you need to purchase the product while logged in. After the purchase, you can check the current and historical orders in 'My Account'.

Since eSIM does not have a physical card, there is no delivery. You will receive an email containing the activation information.

DJB's SIM card can only be used in mobile terminal devices. If used in other devices, it will not work.

eSIM is a technology embedded in the phone, so you can use it directly without buying a physical SIM card.

The difference between eSIM and traditional SIM card is only in the activation and usage methods. Other network plan contents such as speed and reception are the same!

No, one eSIM can only be installed on one device, and it cannot be activated or used on other devices after activation.

If the eSIM plan is accidentally deleted, it cannot be restored. You need to repurchase and reinstall a new plan.

Please make sure that 'Mobile Data' and 'Data Roaming' are turned on. If you still cannot connect, you can try resetting the APN and restarting the device.

Many airports have signal blocking settings, so the network speed inside the airport may be unstable or very slow. It is recommended to leave the airport and try again.

If you have completed all the settings but still cannot connect, you can try resetting the network settings. Reset network: Click 'Settings' - 'General' - 'Reset' - 'Reset Network Settings'. Resetting network settings will only affect network settings, not the phone's own settings.

If you have followed the steps in the package but still cannot connect, please contact our official customer service (Line id: @djbcard). Our customer service and technical staff will help you troubleshoot the network as soon as possible.

Fair Usage Policy: In order to maintain the quality of the network, telecom operators may impose restrictions on users with large usage. Users may feel that the network speed is slowing down or cannot connect. This is set by telecom operators around the world to prevent the abuse of network resources.

DJB's SIM card and eSIM both have flexible duration plans. You can purchase the required duration according to your needs. If it exceeds the duration, you can choose to purchase multiple cards and set different activation dates for use. If you use eSIM, you can purchase the next plan when the current plan is about to expire and use it immediately.

DJB's SIM card only affects the network and does not affect the original settings of the phone. But if your application requires your original number, you will not be able to receive the original number after changing the card. *If you use Line to log in with your phone number, you can set up email login in the Line App before changing the card.

The card with reduced speed can still be used, but it can only send text messages and browse text web pages. If you need to send audio and video pictures or watch content composed of audio and video, it will take more time to load.
