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 rarely happens, but there is a clear mechanism. If the transaction is canceled due to our reasons (such as the vehicle being suddenly seized by judicial authorities during the transfer), we will refund the full deposit you have paid and provide additional compensation according to the penalty clauses in the contract.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.
