I have been using tikona for 2 months and I have to say that it is much better than bsnl wi-max because it has a variety of plans available which is very useful for those people who do not require much data for downloading and also for those who require high data for downloading. I am using a plan of Rs 450 which gives 5gb of high speed downloading and unlimited usage after that.
There are some problems also such as service problem, service of the company is not that good and simonteneous login is also not allowed.
Overall it is a very good ISP and I would definitely recommend everybody for using this.
