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.

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.

Under normal circumstances, it takes 15 to 25 working days. This includes: domestic transfer of ownership (3-5 days), applying for an export license (3-5 days), inland trucking to the port (2-5 days), customs inspection and waiting for loading schedule (5-10 days). Do not trust false promises from other channels claiming 'loading within a week.'
