I was never a big fan of Tata Indicom but a I bought a Tata Indicon Photon+ dongle back in 2012 because a reliable friend of mine recommended it to me. It was a good plan of 10 gb data for 2 months which cost rs. 2000/-.
At first it worked really well. I was getting a speed of 1.5 mbps. But after I used 3 gb, the speed reduced to 200 kbps. I tried the customer care, but they was no help at all.
Next month I got rid of the dongle and switched to Airtel. It was a big mistake buying this dongle and I am never using it again. I don’t recommend Tata Indicom to anyone.
