I am using Tikona from past 4 ½ year, from time they launched at sanpada, navi mumbai. I took it because other options were less and they were providing wireless service. Initially there were lots of hiccups in services, customer care service was horrible.
But as the time passed services they improved. More they improved on their technology part, customer care, field support and majorly on plans.
Alike from other ISP providers who are in Telecom also, Tikona is only into broadband service, I think this the reason they are emerging a strong player in market. They are also launching 4G in some states. I am not an analyst, but still writing this as I am following them since years and this what I felt about Tikona!
