I recently purchased TATA DOCOMO sim. It had 500 MB data free with it, but was not sure if it was with 2G or 3G. So I recharged my sim with Rs 90 to get 100 MB 3G data. When I dialled "*111*1#", I could see that I have 500 MB free and 100 MB data remaining. I thought its 500 MB on 2G + 100 MB on 3G.I started browsing on PC using my phone as modem, and I was getting speed of 1.6 Mbps (which is not possible on 2G). But... the data being deducted was from 500 MB, while my 100 MB data was intact. Only after I finished 500 MB free data, my 100 MB data started deducting.So I called customer care to know about using phone as modem while using 3G internet.CC Replied - "I can only browse on 2G speed when I use phone as modem, while 3G speed will be available while browsing on handset"So is it true that we cannot use TATA DOCOMO 3G handset as modem to browse on PC?
