BSNL Nowadays the wrost sim ever. Review on BSNL 3G Mobile Operator

I am a regular BSNL 3G sim user. I am using this sim from last 7 years. And nowadays when jio sim comes on us. The BSNL goes down, just like calls are not properly clear sometimes we can't hear any voice of the other who is called us. Lag in network. And so data comes the most wrost than idea. In our area the wrost data network provides IDEA because a lot charges we should pay for data and the data network is too poor. But now BSNL is same as like. I do data pack for 3 months unlimited per day 3 GB 3G . but I cannot use enough 200MB per day the internet is not running properly even there is difficult in browsing to. So nowadays I stopped using bsnl sim. And my data offer is still active in that sim either I can't use it.Signal all the time getting out of range.Cannot use data properly. When they say 3G offer we enough can't use 1.5G network speed that much slow.While calling, the voice of the opponent cannot hear properly. Sometimes cannot hear nothing.So I request you to that BSNL 3G sim coming wrost and wrost day by day.Thankyou
