Last week i took some time to add mobile 3G internet connectivity to my Epc using my Nokia e61 as a 3G modem.
My phone supports modem support using the USB data cable, bluetooth or the integrated WI-FI.
I plan to go for the cable first since i always carry one around and being mobile often means draining as less power as possible from both my Epc and my mobile phone.
First of all you need to make sure you have the Debian repositories in your /etc/apt/sources.lst and theninstall wvdial by using the install command apt-get install wvdial
After the installation you will need to modify your /etc/wvdial.conf in order to build up the internet connection.
This is just a basic example but it should work with the current Nokia phones:
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Baud = 460800·
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Phone = *99#
Password = blank
Select the Suite connection type on your phone when you connect it via the USB cable and then fire up wvdial.
