Hello friends, today I am telling about bsnl operator. Before a couple of month, I also use bsnl sim. There 2g network is good and good also in calls but in use of internet it is very bad. You cannot use internet in 2g network it is requir 3g network but when you turn on 3g then also you cannot running internet. Because, there are low networks in 3g. It is not good according to me and I am not impress of bsnl service. I use many times of bsnl internet but every time there is slow speed problem. After that, I port my number in other operator. However, there is one more problem is that, every operator gives life time validity but bsnl gives only 6 month validity and you will recharge in every 6 month.
