As per my personal experience I can say that as compared to the other Telecom networks BSNL three G data card is not giving the good connection and high speed internet for the use of Surfing in the web and for downloading the videos and different type of files from the internet source now the 3G has become old so BSNL should upgrade is quality of network as like the other if you ask me the personal opinion then I can let you know that as compared to the BSNL other network companies like the Airtel Vodafone and the jio are giving the good amount of data as well as the high speed internet facility for the customers .BSNL is a renowned company and it is government telecommunication network him many parts of the country in different offices you can see the BSNL Broadband and the network system although it is a good and reliable but lot of improvement is to be taken for improving the service to a better one.
