I have taken TATA Photon + 3.1 Mbps on Feb-6th-2010. Surprisingly activation is done in 20 mins. I have paid Rs.3600/-. There is an offer going on. First month rental is free.The sales representative in TATA INDICOM showroom suggested me to activate the connection under 1500/- @15GB free per month and suggested me to change the plan according to my requirement, after the free period is over. But we need to call the customer care to in 2-3 days advance. Happily went to home and connected to my laptop. Alas, what a speed.
I had a billing issue earlier.It was resolved after multiple visits to the customer service center.Though I am not happy about the customer service, the product is worth having.
