So, let’s say that in my V70 (three months old) I’m using the factory built-in car phone with my “Flexi-Card” from E-Plus. It’s a second SIM card for my mobile phone number. Each card is given a certain priority. Are both devices, i.e. mobile phone and car phone turned on, always ring the phone when a call is made, first. All SMS messages are sent only to the device with priority 1. Until now I have the card with priority 2 in the car phone. During the journey I turn off the phone. Now, when a second call is received during a telephone call, it does not get a seat sign, but ends up right on the mailbox. This will inform me by SMS about a new call, but the SMS will only go to the device where the card with priority 1 is located – so the phone is switched off, however, you can also assign priority 1 to me.
