We can purchase the hardware (diagnostic device) on your behalf. However, the original online diagnostic accounts (especially those involving anti-theft programming and module matching) have strict domestic IP location and real-name authentication restrictions, making it very difficult to log in stably from overseas for a long time, and we cannot guarantee technical support for this.

Before shipping you should hold: the sales contract and commercial invoice, the export declaration (customs form showing the VIN), the vehicle registration certificate, and the bill of lading or rail waybill once cargo is loaded. Verify them like this. The VIN on the invoice, the export declaration, and the waybill must be identical, character for character. The registration certificate should show a clear ownership chain with the seller as the current owner; ask for a scan before payment. The export declaration proves the car legally left China and is essential for customs clearance at destination. If the exporter cannot provide the registration certificate or hesitates on the VIN check, pause the deal. Also confirm who handles the document courier: originals should arrive before or with the vessel, because many ports will not release a car without original bills of lading.

Most new car manufacturers' e-SIMs are directly soldered onto the T-Box motherboard (surface-mounted) and cannot be removed and replaced like a phone. Unauthorized desoldering of the motherboard may cause complete communication failure in the vehicle, and we strictly prohibit this operation.
