I have purchased Tata Indicom 2.4 Mbps Photon 800 plan in the last week of Feb 2009. I asked the sales person of the shop before signing the application about the speed that I will get. He told me that I will get not less than 1.5 Mbps.
To my suprise, the download speed is not going beyond 300 kilo bits/s. I am not at all satisfied with this connection. Even after getting connected with HSIA at full signal strength, I am getting only 200-300 kilo bits per second in my area Tambaram, Chennai. I tested in Raja Annamalai Puram, Chennai here I am getting 500-600 kilo bits/s.
Now a days I am encountering frequent connection drop outs that too connection mode slips to 1X mode. Sunday night it drops to 30 to 50 kbps. Speed is not constant. When I questioned the staff at Tata Indicom office at West Tambaram about speed they replied that 2.4 mbps is the speed of the device not connection. So, beware 2.4 mbps is the full strength of the modem, not connection speed. On top of this sales people are hiding the fact that it is a post paid connection. What you will do with the device when your ISP is dead slow.
