I am thinking of shifting to MTNL broadband from Airtel. Can any Mtnl broadband user in delhi give a review about their service, speed and costs.

I have my own telephone and a TP-Link TD-W8968 Wifi Router. Will this router work with MTNL and also how much charges I need to pay while registering since I have my own equipment.
