BSNL is the indian government company which prives the telecommunication in the whole country. BSNL 3G data card is one the product of BSNL which is uses by many persons.it support 7.2mb/s speed, but the biggest drawback is that, this product is useful only at those areas where the network is proper. it can give you speed of 1mb/s downloading but if you are away from the BSNL tower then is not possible for you to get a moderate speed. The another drawback is its customer support, if you are facing any problem with your data card then you have to wait for their(bsnl employees) response to fix it. so my total experience with BSNL DATA CARD was not so good.
