Just got Tata Indicom Wimax broadband installed. I was pleased with their service. I Applied for it on Thursday; got the verification call on the same day and they were ready for installation the next day (as they had promised activation within 24 hours). As I will be at home only on weekends, got it installed today. Everything went smoothly.
They installed a small antenna at the roof. Thanks to Wise-Techie, his post was very helpful in getting an idea about it. The whole process took less than an hour.
I am happy with the speed and hope to write a detailed review when I find time.
