Using CDMA Wireless Modem in Ubuntu

Using CDMA USB Wireless Modem with NTC Sky Phone R-UIM in Ubuntu!

Things needed:
CDMA USB Wireless Modem- ~3000 rupees.
R-UIM Card from NTC ~1200 rupees.
Ubuntu 7.10 (Not sure about other versions!)

Just Put the RUIM inside the wireless modem and plug it to the USB Port.

1. Put in the RUIM into the device and insert as USB.

2. Now you need to edit the file called /etc/wvdial.conf by the command 'sudo nano /etc/wvdial.conf'
This is my setting:
[Dialer Defaults]
In it1 = 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 = #777
Password = 9741147061
Username = 9741147061
make sure that the password and username is the same.. that is.. your phone number!
save the file using Ctrl+X

3. Now edit the file  /etc/network/interfaces  by the command 'sudo nano /etc/network/interfaces'
auto lo
iface lo inet loopback

iface ppp0 inet ppp
provider ppp0
now save the file again using Ctrl+X

4. Now the file called /etc/resolv.conf is edited using 'sudo nano /etc/resolv.conf
save again using Ctrl+X

5. :) You are done.. now you are just so close to surfing... wait for a second now.. now restart your machine...

6. In the terminal type : 'wvdial'
you will now get:
abish@lappy:~$ wvdial
