I bought Tata Indicom Photon+ because I had to travel very frequently due to my buisness works. It was a great plan of 5 MBPS.
It offers 10 GB for 2 months but despite of my efforts I couldnt get more than 250 kbps. I was really frustrated and angry because I had to do some serious business video conferences with some of my very important clients, which was thoroughly interrupted because of the poor network.
The worst thing about this is the customer service. They cant care less about your problems and most of the times the numbers do not work. After a month I switched to Vodafone.I had some really frustrating experience with them and I am never going back to them and neither should you.
