It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blind electrical modifications on modern integrated circuit vehicles.

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 understand that the power battery is the core asset of an EV. Before export, our technical team will use professional OBD diagnostic equipment to read the underlying data from the Battery Management System (BMS). We will provide you with a technical report that includes key indicators such as battery health percentage (SOH), cell pressure differences, and charge-discharge cycle counts. If the SOH is below our established export safety standard (usually above 80%, depending on the vehicle's age), the vehicle will be intercepted and not sent overseas.
