As well as I know tikona does not provide there service to every city in india. But I am jappy that my area is covered with tikona network. I live in jhothwara, jaipur. Recently I have take the connection. I am using it . And I am happy with it. Because I have getting very good speed with tikona. I have took plan of 500 in which I got 15 gb with 4 mbps and unlimited 512 kbps. But I am going to change my plan with 400 rs. Because there I will get unlimited access of 1 mbps. That is enoigh for me. I will suggest you that if your location have the tikona service then please take it. Because now a days price of tikona plans are continiously decreae.
And it is not costly. Now if you have budget of 400rs then also you can purchase the plan. And I am guranteed you to that it will never stop like other bsnl network. You can also go for airtel but it will too much costly.
