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.

The storage area at the roll-on/roll-off terminal is entirely outdoors, which is standard practice at ports worldwide. During the few days vehicles wait to be loaded, they will inevitably be exposed to sun and rain and accumulate dust. We will not provide custom car covers as this would significantly hinder the efficiency of dock workers moving vehicles.

Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.
