I Am Using Tata Indicom Photon+ for 6 Months, it has very poor connection and very bad service, It will never shows full connection, It shows Speed off 600 Kbps but gives maximum of 60 Kbps, I called to customer care for my issues, they always said that we are working on it you are out of area, sometimes it doesn’t even connect, it easily stopped working in rainy season.
It is the worst internet service I have never seen, so I would not recommend you to use this network.
