I have a problem with the handsfree signal indicator in my car. However, only if I disable one of the two simcards. If both simcards are active, everything works fine. If a card is deactivated, the indicator will stop working after a few minutes (radio cell change?) and I can not make a call by the car.
I have reported the problem to the support, but they do not really want to help.
Has anyone else the problem?
