I have a Tata Photon Plus USB data card and I want to use it on my Android phone from my desktop or laptop using a WiFi adapter. Is this possible? I am using a Windows 7. Please explain step by step clearly.
If I understand you correctly, you want to use your phone a broadband router, in effect, to allow you to access the internet from your PC. This is called wireless tethering and the feature is built into some versions of Android. See the excellent article on the subject at http://www.howtogeek.com/170302/the-htg-guide-to-tethering-your-android-phone/.
