What a crap FUP. And worse, after FUP limit, a 5 Mbps becomes 128 Kbps!!! LOL!! This is the most ridicuculous speed shift I am seeing. If this is true, they must be joking! I thought broadband in India was defined as more than 256 Kbps, here they are going even below that Day by day, these guys are worsening. Unlimited plans have meaning only if they have no FUP or if they have an 'acceptable and logical' FUP. Airtel, Hathway etc. are alien to the words like 'acceptable' 'logical' etc. I sincerely suggest, the best is MTNL. Though some of Triband users may have issues which are not resolving, by far, most of Triband users are happy; and believe me, the higher authorities are also good. On the other hand, the higher authorities of private players like Hathway etc. are just not approachable and are least bothered about the customers. Even if you mange to get them (I did), you will tear your hair after meeting them. Try contacting a higher authority from Parel Office of Hathway and you will see what I mean.
MTNL rockssss!!!!
