Is there a way to use my E71 as a cellular modem on Ubuntu 8.04? I'm using a USB cable to eliminate any Bluetooth problems, and prefer USB over Wi-Fi sharing solutions.

Thanks, Adam

Following my question at, the solution seems to be configuring wvdial.conf as:

[Dialer usb] 
;Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 
init1 = AT+CGDCONT=1,”IP”,”” 
Modem Type = USB Modem 
Phone = *99# 
ISDN = 0 
Username = ” “ 
Init1 = ATZ 
Password = ” ” 
Modem = /dev/ttyACM0 
Baud = 460800 

You might want to change '' to your provider's url. Actually, I was just guessing mine - I'm not sure the url is entirely necessary.


su -c "wvdial usb" 

Some magic happens:

--> WvDial: Internet dialer version 1.60 
--> Cannot get information for serial port. 
--> Initializing modem. 
--> Sending: ATZ 
--> Modem initialized. 
--> Sending: ATDT*99# 
--> Waiting for carrier. 
~[7f]}#@!}!} } }2}#}$@#}!}$}%\}"}&} }*} } g}%~ 
--> Carrier detected.  Waiting for prompt. 
~[7f]}#@!}!} } }2}#}$@#}!}$}%\}"}&} }*} } g}%~ 
--> PPP negotiation detected. 
--> Starting pppd at Sun Jan 24 10:01:27 2010 
--> Pid of pppd: 11872 
--> Using interface ppp0 
--> pppd: w[7f] 
--> pppd: w[7f] 
--> pppd: w[7f] 
--> pppd: w[7f] 
--> pppd: w[7f] 
--> local  IP address 
--> pppd: w[7f] 
--> remote IP address 
--> pppd: w[7f] 
--> primary   DNS address 
--> pppd: w[7f] 
--> secondary DNS address 
--> pppd: w[7f] 

wvdial stops here. Now type, in another window:

sudo route add default gw ppp0

Of course, use the IP you've got from your provider, not the one listed here.

And you're done.
