ok, good to know. one thing I observed; once I got the car on the wifi, then my phone seemed to join the car's wifi. the car was acting as a wifi hotspot which my phone auto-joined (I presume because of the pre-existing relationship with bluetooth and apple carplay). but then carplay didn't really want to run. so I turned the car's wifi back off.
I added the vivaldi web browser, the youtube app, and the accuweather app. the web browser works pretty well. I think it works on the passenger screen too
the "basic" data plan provides date for the car and the car's apps - but not internet for any devices joined to the wifi hotspot - you have to upgrade to the "premium" data service for the car's wifi to provide interenet services to phones and tablets connected to the wifi hot spot…
you can get information abou thte data pass from the myPorsche app…
