I think among all the networks I have used , BSNL is worst provider of network.
2g, 3g works at similar speed and sometimes even don’t work.
It is just a wastage of money by buying BSNL sim because network is poor at every place either in a smarycity or rural area.
It needs to be improved otherwise it will lost its custmors in future because of poor network facilites.
Everyone complaints about its poor network.
Calling network is little bit okay but the internet facility of BSNL is very poor.
