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.

During the stationary steering test, the technician will check the smoothness of the steering wheel from full left to full right, looking for any unusual noises from the steering gear; they will also inspect the hydraulic power steering pump (if present) and the seals of the steering column for any hydraulic fluid leakage.

Cross-border after-sales support mainly comes from three channels: 1. Contract terms: Reputable exporters commit in the sales contract to engine and gearbox coverage for 30 days after pickup, excluding wear-and-tear items. Get this in writing before paying. 2. Inspection report: The pre-shipment inspection report is your baseline. If the car arrives with problems that contradict the report (e.g., hidden accident damage not disclosed), you can file a claim against it. 3. Parts supply: For mainstream Chinese brands, spare parts channels exist in Russia, Central Asia, the Gulf, and Africa. Many exporters will help you source and ship parts after delivery. Practical tips: inspect the car on arrival and photograph everything; report any issue in writing within 48 hours; keep all shipping documents. Claims filed weeks later are hard to prove.
