Hi @ all!
This is an useful article for all people which, like me, use “Naviga3″ to surf the net when they are without an ADSL connection.
So we can be always ONLINE.
This article has been written to help my great COOK friend Doctor Mazzilli (if you don’t remember him, go here).

So Shall we start? OK.
First of all it could be better use a BT connection (’cause there are some phones that don’t allow to recharge them while connected with an USB cable).

Init

sudo apt-get install bluez-utils kdebluetooth kppp
note: you can install kppp
even if you are using GNOME under (brown shit! :P) UBUNTU. And you had to change also kdebluetooth in bluetooth.

Configuration

Now we can continue in two way:
-Using wvdial
-Using kppp

Because I don’t remember if my COOK friend (but he is also an UNDERGRADUATE STUDENT OF IT ENGINEERING like me) has installed his dial-up modem under his distro, I must explain both.

First search you BT device with:
sudo hcitool
then bind it:
sudo rfcomm bind /dev/rfcomm0 xx:xx:xx:xx:xx:xx 1
where xx:xx:xx:xx:xx:xx it’s your device’s address obtained with previous hcitool.

wvdial way

sudo nano -w /etc/wvdial.conf


[Dialer bt]
Init1 = ATZ (for Nokia) / AT&F;+CGATT=0 (for Motorola and LG)
Init2 = AT+cgdcont=,”ip”,”naviga.tre.it”
ISDN = 0
Phone = *99# (for Nokia) / *99***1# (for Motorola and LG)
Modem = /dev/rfcomm0
Username = ”
Carrier Check = no
Password = ”
Baud = 115000


So:

wvdial bt


and YOU ARE ONLINE!

kppp way

Open kppp from start menu - internet - kppp
Click “Configure” and then new account and manual configuration.

Dial:
-Account Name: Naviga3 (or what you want)
-Phone number: *99# (for Nokia) / *99***1# (for Motorola and LG)
-Authentication: PAP

Press OK.

Modem - NEW:
DEVICE TAB
-modem Name: your phone
-device: /dev/rfcomm0
-flow control: nothing
-line termination: CR
-conn speed: 115200

Then move to MODEM TAB:
modem commands:

initializ string 1 : ATZ (for Nokia) / AT&F;+CGATT=0 (for Motorola and LG)
initializ string 2 : AT+CGDCONT=1,”IP”,” naviga.tre.it”
dial string : ATD
and remain the others as they are.

Press OK, Press OK.

Insert username and password as you want and YOU ARE ONLINE!

Finally use vnstat and my PeriodicCmd script to check your internet traffic.

Special Thanks to my Friend Doctor Mazzilli for his delicious dinners.
