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.

For vehicles frequently dispatched across such latitudes, we will conduct fatigue resistance checks on chassis rubber parts that are twice as stringent as those for vehicles in temperate regions.

Yes. Even if you purchase 100 vehicles, we adhere to "one inspection per vehicle, one file per vehicle." Each vehicle will have its own independent inspection report with a unique VIN code, which serves as the sole proof for quality traceability.
