I use wvdial to connect to my 3G modem as below:

1. install wvdial :

   sudo apt-get install wvdial

2. edit the wvdial.conf file by any text editor say gedit by below command:

   sudo gedit /etc/wvdial.conf

3. copy paste the following lines in wvdial.conf

   [Dialer a]
   Modem Type = Analog Modem
   Phone = *99#
   ISDN = 0
   Baud = 460800
   Username = " "
   Password = " "
   Modem = /dev/ttyUSB0
   Init1 = ATZ
   Init2 = at+cgdcont=1,"ip","your apn"
   Stupid Mode = 1

4 connect using ( you can change the name as you want by replacing a in above wvdial.conf )

 wvdial a 

(just add apn according to isp you are using like aircelgprs for aircel, bsnnet for bsnl etc. in wvial.conf file in place of "your apn")

nmtui

It is a very basic UI for Network Manager. More convenient than "nmcli" IMHO.
