No. It only charges you for the minutes you normally used on your handheld cellular device you pair to it. The car just acts like a fancy bluetooth speaker phone. If you have OnStar active and press the button to the left of the blue button on the mirror or press the phone button on the radio w/o your phone paired, then it will go to OnStar call minutes.Just bought this car. My question is setting up bluetooth calling does that charge you anything extra??
