All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.
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 vehicle's wireless charging module (usually Qi protocol) is considered functional as long as it can properly sense and light up with our tested mainstream models. The seller is not responsible for charging issues caused by the buyer's personal electronic device compatibility.
