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.

Vetting takes a day and can save you thousands. Work through this checklist. Verify the business: ask for the company registration number and check it on China's National Enterprise Credit Information system or a commercial registry tool. Confirm the registered address matches where they claim to operate, and that their business scope includes vehicle export. Check export credentials: they must hold a used-vehicle export license issued by Chinese commerce authorities. Ask for the license and a recent export declaration showing they actually ship cars. Test their knowledge: a real exporter answers detailed questions about your destination country's import rules (age limits, left/right-hand drive, emission standards) without hesitation. Vague answers about your own country's requirements are a red flag. Structure payments safely: small deposit (10-20%), balance only against inspection reports and shipping documents, ideally through a payment method with recourse. Refuse full prepayment by irreversible transfer—no legitimate exporter requires it.

If your remitting bank requires verification of the transaction's authenticity, we will promptly provide: a commercial invoice (PI) signed and stamped by both parties, a scanned copy of the vehicle purchase contract, and our legal export enterprise registration certificate from the Ministry of Commerce in China.
