Following my question at whatsup.org.il, 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”,”orange.co.il”
Modem Type = USB Modem
Phone = *99#
ISDN = 0
Username = ” “
Init1 = ATZ
Password = ” ”
Modem = /dev/ttyACM0
Baud = 460800
You might want to change 'orange.co.il' to your provider's url. Actually, I was just guessing mine - I'm not sure the url is entirely necessary.
Now,
su -c "wvdial usb"
Some magic happens:
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Modem initialized.
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#

wvdial stops here. Now type, in another window:
sudo route add default gw 110.195.166.229 ppp0
Of course, use the IP you've got from your provider, not the one listed here.
And you're done.
