We used to have mtnl broadband connection at our home but it used to create many problems then I changed to Hathaway broadband and now the internet is working very good.
They have very good internet plans which are very value for money. We've been subscribed to the monthly plan of Rs 650 in which we get 50mbps until 15gb and after that it reduces to 1mbps. The speed is pretty good and their service is extraordinary. Once there was some breakdown is working due to a storm in our area and we complained it to Hathaway complaint no. Just after 3hrs the machanic fixed the wire and internet started working again.
We are free up of slow internet speeds of your broadband then I will recommend you to upgrade to Hathaway. Its worth it.
