BSNL is one such company which I just hate but still I use it. I am BSNL COMBO 845 broadband plan user and this plan offers me 6gb of 2mbps speed and afterwards unlimited af 512 kbps. Dispite the fact that bsnl IS providing perfect speed they are promising but still their speed is very very slow as compared to other companies for example a ISP called ACT broadband in hyderabad is offering 10 MBPS SPEED AT THE SAME COST. now this is where bsnl lags in this competitive workd they just never try to upgrade u knw.
Their plans have been the same from a very very long time. Minor adjustments have been their but they are just negligible. So I should say if u r thinking of purchasing bsnl broadband then THINK AGAIN!
