Three years ago I use to use MTNL because that time only MTNL is providing Broadband, yes there is BSNL is also available that time but I choose MTNL. And guys I really had bad experience with that. MTNL is very slow internet if you search for facebook on google than it will take minimum 5 Min to open a Facebook page.
And also in my area there was not a proper internet connectivity.
If you choose a good internet service pack than its okey you can surf with that but if you choose low budget internet service pack than I am not sure if you are able to open a google search engine.
-Bad internet connectivity.
