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.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

As long as you provide us with a genuine and valid bank SWIFT MT103 wire transfer message (receipt) within the payment deadline specified in the contract, we will reserve the vehicle and continue with the port operations, even if the funds are held up in the intermediary bank for several days.
