I was using 845 combo plan which offered 2 MBPS speed upto 6GB download and after that the speed went down to 512 KBps for unlimited download which is very low.
First of the prices are too high for which better alternates are available who provide more download and speed too.
Secondly with bsnl there are trust issue tht is you cannot rely on BSNL as it can go off anytime and specially if you reside near a construction area then you gotta go mad with the service of BSNL as their wires get broken and they take a long time to repair them. So never rely on BSNL its my personal experience . Go for some better alternative and stay connected : ) I hope this review will help you with your decision.
