MTNL newly offer is for fiber internet. They said it is very fast than the old wire that gave only 1 mbps. they developed a new network of fiber in mumbai and have come up with fiver internet monthly plans.
my company bought mtnl because our office tata connection was slow and giving disconnections very easily. and the speed is mtnl of very good. I work late and download movies online. the download speed when I am only person in office is upto 9 MBPS sometimes and in day also it is some 4-5 Mbps.
the cost per month is only rs. 800 monthly and after a lot of download the speed is stopped at 1 mbps. but 1 mbps is also good. I like this connection.
