I am a resident of Noida and have been using Tata indicom Wimax from past 6 months. I get good download/ surfing speed, consistently. I can hardly remember disconnections from the time I have started using it.
This gives Tata an edge over the other service providers in the market. The only "cons" in the service which I find is that its marginally expensive then its competitors. I have not had the opportunity to test there service because I did not have to call them for anything. I am satisfied with my service providers. I ll give them 10 on 10 for speed.
9 on 10 on service and 7 on 10 on Value for Money!
