    Cayenne dual sim

    I cannot get my 'dual' sim to work in the Cayenne. Obviously I have one in my gsm and one in my Cayenne. The sim's I am using are purposely made for this use. However if I switch off the Cayenne, go out and try to phone with my gsm on the first attempt I get 'connection error' when I try it again all is OK. I don't have any issues the other way (in the car). Pretty annoying because when people try to call me on the gsm and I am not in the car, they get a 'phone is switched off voice message'. At the moment I have to dail a number coming out of the car just to get my gsm connected again. Am I dealing with a fault in the Porsche phone system or is it me??? I have switched the sim's but no cigar either.

    Re: Cayenne dual sim

    there is a combination of buttons you have to use on your phone or on the PCM to activate either to receive calls when switching from one to the other. it's something like #12*

    check with your mobile provider.

    it's nothing to do with the Cra's PCM. you would have to do the same between two handsets.

    Except my 911 PCM doesn't accept these sim commands and thinks I'm dialing a phone number.. In my situation I'm switching active sims only - not two numbers.

    Thanks guys!

    Muhri,

    How do you work yours? I basically have two sims for one number however only one can work at the time. It should work that the brochure says it switches between car and gsm without activation of either. As soon as I switch on the car, the car activates the SIM (and this works --> great) and when I switch off the car it should deactivates the car SIM to switches back to the gsm (doesn't work). Pretty useless system if I have to activate my gsm every time (getting old and forget). It's a shame that she doesn't have bluetooth as this is such a simple and convenient way transferring the phone to the car.

    I still think it is the cayenne's PCM what is at fault. I don't have to do anything when going in the car and calls are coming through (and I can make calls) I still doesn't understand why it doesn't work the other way (switching the car off and registering the gsm again)

    Re: Cayenne dual sim

    Mine is not automatic, I have three sim cards. One I keep in my Mercedes, one in me porsche, and ofcourse one in my handset. What happens is, I can set the master SIM by using a sim command (*123#) - All of the sims if on can make calls and send SMS but can not receive calls. Only the master will ring. If I am in my Mercedes, I give this command and it works - if in the porsche, the PCM thinks I am dialing a phone number (The merc has a phone with a cradle, the porsche has PCM only) ... so its kinda pointless to have to accept calls on my handset and can dial out of the car ... I called my teleco and they were clueless, porsche dealership - just as clueless

    I have nearly the same problem when using dual sim's with my new PCM3.

    But my problem is that my PCM does not activate my SIM even if i have switched of my mobile. I guess that this happens when im am shutting of an on the car very fast whithout longer delays in between (e.g. at the gas station).

    Did you have a similar problem as well? Do you have a PCM2 or PCM3 or doesent it matter?

    Re: Cayenne dual sim

    This problem is with PCM2 in a 997, I'm not anticipating this problem with PCM3 in the cayenne since I got the bluetooth module and hence no need for another sim in the car.
