If the car sends data back to the mothership, then who pays the phone bill ? Say's it's about an SMS size each time I use a car so maybe 0.02$ a day ? 200 days/year, 10 years => 0.0220020=80$ and they sure have discount, so it's very cheap...
IS there a way to know where the chip is ? Is there a way to jam it so it can't send information back ?

You do. The bill is included in the purchase price of the vehicle. The manufacturer sources data SIMs, pays for data ahead of time, and that’s to the cehicle price.
