I am using Spectranet from 2 years now and I am satisfied with their service. There are many internet plans so I have the 750kpbs plan with monthly rental of Rs 750. The speed of the internet is good and the connection reliability is also nice. Whenever I face any problem I just call them and they check the problem and fix it quickly. So, the support of this ISP is good and the performance is also good.
I would recommend it to others because my experience with Spectranet is good enough and there is no problem.
