Call disconnection while the vehicle is in motion

A call may be disconnected if:
• there is insufficient network coverage in certain areas.
• you move from one transmitter/receiver area (cell) into another and no channels are free.
• you use a SIM card which is not compatible with the network available.
• you are using a mobile phone with "Twincard" and the mobile phone with the second SIM card is already logged into the network.
