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.

Unfortunately, cross-border used cars are not covered by the manufacturer's free recall. If a physical recall occurs involving safety issues (like brake pump defects), we will notify you and offer improved new batch parts at cost price, but you will need to cover the labor costs for the replacement.

The "usage type" section on the vehicle registration certificate has legal validity. Any vehicle that changes from "commercial" to "non-commercial" has a usage intensity far exceeding that of personal vehicles, and we will label these prominently. Such vehicles are usually cheaper but have more severe mechanical wear.
