There is only one place where Tikona is good, where there is no other ISP in the area. May it can be good for other cities. I am using tikona for last 3 years(not having any other ISP) and one thing I can say.
Please raise a request of shifting in every 4 months because for first 4 months it is like smooth like butter and then it is like hell. Customer care is good but you cant have a service which is breaking per week.
