After I start wvdial, I get the following lines

$sudo wvidal

 WvDial: Internet dialer version 1.61
    Initializing modem.
    Sending: ATZ
    Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

    pppd: `�9[08]X�9[08]
    secondary DNS address
    pppd: `�9[08]X�9[08]

This is my wvdial.conf file;

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = #777
Password = 9382741646
Username = 9382741646

Is there any mistake in the config file ?

Should I do any thing after I run wvdial in terminal to get the internet to work ?

Found the answer and thought to share it with you guys.

Install the these packages in the following order

  1. libwvstreams4.6-base_4.6.1-5_i386. get this -
  2. libwvstreams4.6-extras_4.6.1-5_i386. get this -
  3. libuniconf4.6_4.6.1-5_i386. this one -
  4. wvdial_1.61-4.1_i386. and finally this one -

Download the amd64 for 64bit os and i386 for 32bit os systems.

Then go to /etc/wvdial.conf in sudo mode and edit it using vi with the following configurations.

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
CBaud = 460800
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = #777
Stupid Mode = 1
Password = Your number
Username = Your number

the Modem = /dev/ttyUSB0 value may be /dev/ttyUSB2 based on which port your device is attached.
