I wonder if you could repurpose the cars SIM card (eSIM or otherwise) / cellular modem for your own use? Like presumably the manufacturer is paying a data plan to a cell provider. If the connection is not locked down to specific traffic I wonder if it could be reused
Who pays for the cellular data plan
