When i was on the tata docomo facebook page, i saw this status msg by them:"Now calculate EXACTLY how much you can save with a TATA DOCOMO connection! Check it out for yourself by going here: The Second Effect" ....so i went on the link and i realized that you can actually know how much you can save in your call rates..its the new savings module that they have devised that compares your current mobile call rates and then let you know how much you can save through Tata Docomo!
