We will use wvdial for using EVDO. Wvdial dialer is PPP dialer, which dials a modem and starts PPP to connect to the Internet.

Steps to connect are:
1. As root, in terminal, type :
# wvdialconf /etc/wvdial.conf
2. Now edit /etc/wvdial.conf, type:
# vim /etc/wvdial.conf
2. Now enter your username, password, & phone no as:
Phone = #777
Username = cdma
Password = cdma
3.Check your wvdial.conf file for these two entries:
Stupid Mode = 1
Auto DNS = 1
If they are not there, add them.
4. Save the file wvdial.conf and exit the text editor.
5. Now type sudo wvdial in the terminal and the EVDO should start working

FOR REFERENCE:
My /etc/wvdial.conf contains:

[Dialer Defaults]
Modem = /dev/ttyUSB1
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
Phone = #777
New PPPD = yes
ISDN = 0
Username = cdma
Password = cdma
Baud = 9600

I have seen lots of forum where newbies face problem while installing lamp server. So, what they can do is directly file the following line of code and everything will be done automatically:

sudo apt-get install apache2 apache2-mpm-prefork apache2-utils apache2.2-common libapache2-mod-php5 libapr1 libaprutil1 libdbd-mysql-perl libdbi-perl libmysqlclient15off
libnet-daemon-perl libplrpc-perl libpq5 mysql-client-5.0 mysql-common mysql-server mysql-server-5.0 php5-common php5-mysql

Another alternative that can be done is:
File the following commands in sequence:
1: sudo apt-get update
2: sudo apt-get install lamp-server^
