Every two in three days your net get cut. Bsnl WiMAX service is veryy very bad. After installing wimax. If you have any complaints then they will not accept your phone call.
If they pick your calls they assure that they will provide you full support and they will come by your house check the connection that day
But after 3 or 4 days of waiting and calling, you by yourself have to go to the office for complaint . its really frustrating.
