i have installed ubuntu 12.04 and connected my airtel 3G data card. after blinking there is no response. but i checked using lsusb command. it shows my device.
bus 003 device 004: id 12d1:1446 huawei tech corp E1552/E1800(hspa modem)
Run sudo -H gedit /etc/udev/rules.d/50-huawei-e1552.rules
And paste to the editor these lines
SUBSYSTEM=="usb",
ATTR{idVendor}=="12d1",
ATTR{idProduct}=="1446",
RUN+="/lib/udev/modem-modeswitch -v 0x%s{idVendor} -p 0x%s{idProduct} -t option-zerocd"
Save the file.
Then run in terminal
sudo service udev restart
After that you will be able to crate a new connection in Network Manager.

.
Sometimes the best solution is to use the program that is shipped with the device itself. This is especially true with Huawei dongles.
tar.gz
file in a directory named Linux
.Extract it
tar -xzvf filename.tar.gz
Open a terminal and run the install.sh file
./install.sh
Once installed a program will be appear on your Ubuntu dash which you can use to connect to internet as same as you'd do in a Windows machine.
lsusb
to your question.
