BSNL BroadbandI am using BSNL since last year and I face some problem that at starting of month they provide good speed but after 10 days that speed is drop but it give OK speed and I am OK with it.
BSNL Broadband provide an telephone which is good think and they provide free calling on Sunday and free unlimited calling at night from 9pm to 6am that is good think.
Service and support is good and I personally did not face problem so it depend upon you area.
