Hi everyone, this is my first visit on this site. I have a Boxster S 2005 with a PCM 2.1. I want to use the integrated phone system which required a SIM card. In order to activate the card the service provider requires the phone system serial number or IMEI. I obtained several number from the PCM by pressing "MAIN" and "TRIP" simultaneously in `SWversions`. According to the service provider he could not find any of the numbers, I gave him, in his system that would confirm that my PCM system would accept the HSPA SIM card. I am not sure but I believe from the info in my PCM could be a type "A"
