One thing that caught my eye on it (GT3)
So this PCM has a built-in SIM as well as a SIM slot. I wonder what network it connects to....Integrated 4G/LTE compatible SIM including data for the Porsche Connect Services (Navigation and Infotainment services only, music streaming and WiFi not included). Detailed information on Porsche Connect can be found at www.porsche.com/uk/connect.
To use music streaming and WiFi, data packages will become available to purchase in the Connect Store. Alternatively a data-enabled SIM card and a separate valid subscription to a mobile network provider (subject to charge) can be used instead of the Integrated SIM.
