Got myself a BSNL Broadband connection. I researched enough and it does look like a reasonable alternative.
There are issues of course. It took them 15 days to get me connected. Actually they took 14 days to collect the documents and initial payment. Connection was delivered and enabled in just one day!
Problems right now? Speeds are not good. I plan to enquire about the slow speed problem tomorrow. Hopefully they would at least deliver 80% of the advertised speeds.
BSNL does look like a good alternative to me right now. I got a direct number to their broadband guy who handles the things in the backend. Wiring quality seems to be pretty good based on the values shown in modem backend.
Now, the big question is… When to apply for disconnection of my airtel broadband connection!
