It's not mandatory. Four-wheel alignment and dynamic balance are part of routine maintenance. During long-distance towing and sea transport, the suspension may experience slight changes in stress. We recommend that buyers perform a four-wheel alignment locally after picking up the vehicle at the destination port and replacing tires suitable for local road conditions.

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.
