Our system provides basic risk alerts based on the general regulations of the main exporting countries, but the final responsibility for confirming whether the vehicle meets the import country's regulations lies with the buyer. We will rigorously indicate the vehicle's production year, first registration date, and Chinese emission standards (such as National V, National VI) on the details page. We recommend that you submit this accurate data to the local vehicle management department or customs agent for verification before placing an order.

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.
