I am sharing my experience about the bsnl service which I have been using for one year.i did not suggest this service because there are no proper signals.it is only useful for f and f calling.mainly its net is alwats fluctuating.it is very irrirating when using internet.recently when I am writing the review on mouthshut its net is always fluctuating.i got irritated and take the wifi from my friend.so friends dont expect internet too fast from bsnl.i am also trying to portable my network from bsnl.and dont go for it.it is only useful for f and f calling.its customer service is also become too worst.i tried too many times to customercare to complain about net fluctuation.but it did not connect to the customercare.so friends dont go with the dirtybsnl.
