Please don’t buy this product. This has nothing to do with BSNL. This is a cheap chinese product that is fragile and will not charge after sometime. If you want to waste your money, then, buy this product. I bought this from Snapdeal and they are not posting my review on this product at their site. If you still want this product, remit me the delivery charges and I will courier this to you.
My experiance is wosrt with it.
