I have been using Reliance Wimax now since May of this year. It is not without its problems but I live in an area of Ahmedabad, Thaltej, where there are no landlines. I had BSNL before moving to Thaltej and it was also not without its problems. My family and I depend heavily on the internet for work and school. My wife homeschools our children using curriculum from the US. My experience thus far with Reliance Wimax has been very positive even though we have had a few glitches. They have always been very prompt in responding to our problems. We have two 300kbs unlimited connections and, if you can afford it, it is not a bad idea for when one connection was experiencing a problem, the other worked. We have downloaded several MP3 files and a 3 mb file takes about 30 seconds.
