How can I enable a EC156 HSIA modem for internet connection through Tata Photon Plus plan on my Ubuntu 12.04 system (32 bit)

Question: Tata Photon is your ISP (Internet service provider ) right? Did Tata Photon supply you with the modem? – stephenmyall Jul 31 '12 at 8:33

I had the same question, and I ended up at the following post.

However, when I followed the command sequence per this post, I did not use the modem identifier the author has used (1505), instead I used 140b (because that is the value that was reported by lsusb; my output said 12d1:140b). I used 140b wherever the author of this post says 1505.

The sudo usb_modeswitch -I -W -c 12d1:140b command succeeded in identifying the modem and sending a message through the device.

Hope that helps.
