Hi everyone, this is my first visit to 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 numbers from the PCM by pressing "MAIN" and "TRIP" simultaneously in `SWversions`. According to the service provider he could not find in his system any of the numbers I gave him, consequently he could not confirm that my PCM would accept the HSPA SIM card. I am not sure but from the info in my PCM, I believe it could be a type "A" software. Could anyone tell me if the PCM software has to be upgraded to a "B" software for the system to accept the HSPA SIM card? Thanks in advance for your help.
