I tried to implement the answer in Micromax 3G mobile internet modem not being detected.

Here is the output of lsusb.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 010: ID 1c9e:9913 OMEGA TECHNOLOGY 
Bus 001 Device 004: ID 064e:d20c Suyin Corp. 
Bus 002 Device 004: ID 0489:e03c Foxconn / Hon Hai 

With this information, I followed the answer step-by-step, replacing 9605 in the answer by 9913.

usb_modeswitch -c /etc/usb_modeswitch.d/1c9e\:9913

I still do not have my modem detected by Ubuntu 12.04. My laptop is an Aspire 4752ZG.

I totally forgot about this question. It seems that in Ubuntu 12.04 and 12.10, the default Network Connections is enough to fix the connection. Wait for the Modem icon to pop up in the Unity bar after plugging the mobile broadband stick. Right click on the icon and click on Eject modem. It will re-mount itself so right click on the icon again and click Eject modem once more. Wait for a short while and the Network icon should start showing your modem (usually follows New Mobile Broadband). Click on that and follow through with the installation as described, for instance, in this external site: http://daksh21ubuntu.blogspot.com/2012/02/how-to-establish-mobile-broadband.html
