Porsche Car Connect gives you a onboard modem with a SIM card in order for the car to send information to the server then your phone, PVTS uses that modem to send tracking information too.

Porsche Connect Plus (I think it's how they name it now) gives you the apps but those apps don't use the built in SIM card, one need to either pair the car with your phone, or insert a SIM card into the PCM.
