Bsnl just launched new dataone broadband plan. Seems it is launched to have very basic plan and cheapest plan. Though it is very limited plan but now you can get 2mbps speed for just Rs. 125 per month. That is $3 a month. However this plan is lame actually. They are only providing 150 mb data transfer per month. If it exceeds then you have to pay Rs. 0.90 per extra mb. .
