Are you downloading more games and movies. Then dont use BSNL. They only have FUP plans. Means after some time, Your speed will be reduced.
You will get 2 MBPS for first 6 GB. Then 512 kbps. This plan is for 950 rs monthly .Horrible plan ever. If you just see online videos also, this is a worst plan. For downloading 1.5 GB takes 6 hours to complete. on 512 kbps.
So just go for RAILWIRE.
They give good plans with same prices. 900 rs, 1mbps, No limitation. Thats the best plan guys.
