Dear members,I am planning to purchase new BSNL broadband connection at my home.1) Modem: BSNL is also selling modem, but i saw a modem in flipcart "D-Link DSL-2520U ADSL2+ Ethernet/USB Combo Router" whether it works with BSNL broadband?2) if modem is ours then also we need to pay monthly charges?3) we dont have land line at home, so how much it costs total for me to get broadband connection including landline costs with modem/without modem.Thankd
