I got to know about tikona from my friend in my building. Plans offered by tikona are best for eg 30gbs at 4 mps for 750rs only. I applied online and got it installed the same day. The only complaint I have is that make the purchase process a little easier.
PROS:
1) optimum speed.
2) low cost
3) no network problems.
CONS:
2) connection gets disconnected at frequent rimes.
BUT, OVERALL ITS QUIET AFFORDABLE AND CHEAPER BUT I THINK THEY SHOULD REDUCE THE INSTALLATION COST.
