You have to connect to the mobile phone using a USB cable.
If you want, you can deactivate the pin by putting the card into any phone and going through the process you simply have to edit the /etc/wvdial.conf file as follows:
[Dialer nokia] Phone = *99***1# Username = vodafone Password = vodafone Stupid Mode = 1 Dial Command = ATDT Modem = /dev/ttyACM0 Baud = 460800 Init2 = ATZ Init3 = ATE0V1&D2&C1S0=0+IFC=2,2 ISDN = 0 Modem Type = USB Modem Init5 = AT+CGDCONT=1,"IP","ac.vodafone.es";
Then in a terminal enter
- wvdial nokia
and you should be connected
