The steps which i followed are as under:-

(Initially ensure that none of your network connections from the network icon are set to connect automatically otherwise it will automatically start connecting and make the modem busy for the wvdial command. You can edit the connections available in the network icon by right clicking and then editing the connections by unselecting the "Connect automatically" button. This action will be required if you see that the connection icon starts operating. After disselecting connect automatically button you may have to restart the complete process by phusicallyremoving and inserting the modem again so that modem is released. )


1. Create a file named 1e0e:cefe in /usr/share/usb_modeswitch/1e0e:cefe as under
################################################## ######
# D-Link DWM-162-U5, Micromax MMX 300c
#
# Contributor: Zhang Le
DefaultVendor= 0x05c6
DefaultProduct= 0x2001
TargetVendor= 0x1e0e
TargetProduct= 0xcefe
MessageContent="5553424312345678000000000000061b00 0000020000000000000000000000"
Need Response=1

2. Then create /etc/wvdial.conf as under
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Modem = /dev/ttyUSB2
Phone = #777
Compuserve = 0
Aoto DNS = 1
Username = 165
Password = 165
Baud = 460800
Stupid Mode = 1
Idle Seconds =7200
Dial Command = ATDT

3. Then use the following commands
laptop:~$ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 05c6:2001 Qualcomm, Inc.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
laptop:~$ sudo usb_modeswitch -W -I -c /usr/share/usb_modeswitch/1e0e:cefe
Enter the password for root user

4. This command will switch the usb modem from storage device to modem i.e. 05c6:2001 will be converted to 1e0e:cefe, this can be confirmed by using the lsusb command again as under
laptop:~$ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 1e0e:cefe
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
5. You can see that Device 3 is now 1e0e:cefe, this is nothing but the vendor id and product id of the modem.

6. Then use the following commands
laptop:~$ sudo modprobe usbserial vendor=0x1e0e product=0xcefe

7. Now give command as under:
laptop:~$ sudo usb_modeswitch -v 0x1e0e -p 0xcefe -V 0x1e0e -P 0xcefe -M 555343123456780000000000000606f5040252700000000000 0000000000
You should get the following messages:
Looking for target devices ...
Found devices in target mode or class (1)
Looking for default devices ...

-> Run lsusb to note any changes. Bye.

8. Now its time to get connected by dialing wvdial command as uner:
laptop:~$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ

Hi all, Today I learned how to use the bash script to enter the multiple commands mentioned as above in a single file and then just run the file as an application.
For this the script file can be made as under: bash script file named bsnl,sh

#!/bin/bash
clear
sudo usb_modeswitch -W -I -c /usr/share/usb_modeswitch/1e0e:cefe
read -p "Press enter" name
sudo usb_modeswitch -v 0x1e0e -p 0xcefe -V 0x1e0e -P 0xcefe -M 555343123456780000000000000606f5040252700000000000 0000000000
sudo modprobe usbserial vendor=0x1e0e product=0xcefe
sudo wvdial

After saving this file as bsnl.sh(can give any name), just run the file in terminal or add this as application launcher in a pane or desktop to run it just by clicking on it.
