BSNL is an government organization which provide mobile service no doubt then their coverage is best but guys now its 4G era and where are they no 4G till now and even the prices of 3G packs are also high even now what are they thinking now a days each and every packs price are low as we can't even think but bsnl I can't understand what they are doing even their 3G is not that good I had 4 bsnl in my house including me but now only 1 left and I had to port to other number one more worst thing they have they are not providing lifetime validity so you need to charge after every 6 months its all very fed up to charge it wether you are using or not that much but its compulsory to charge it if you want your number otherwise after 6 months they stop oitgoing and incoming worst sim according to now days.
If anyone is thinking to buy bsnl just because it's government so please don't go for it worst sim I must say there are many other and far better service providrs available easily now a days.
Thank you
