I have used BSNL service. It works fine in normal season like summer or winter. But it does not work well in raining season, I complained about this issue to company, every time when I call them, they told me "it should be working fine now", but everytime it hurts me in raining season.
So, I request BSNL broadband servicemen to please resolve this issue. Otherwise it works so well like there is no comparison of internet speed of BSNL with other companies like airtel, connect etc.
They also have reasonable prices of internet service that attracts users like me to use their service.
Thanks
