The main thing of bsnl is network which is only good . The speed of itrenet of bsnl is very poor the speed is very slow it very slow like 2g speed the company should have to increase there speed also . The worst thing of this is that it will deactivated after six months so we do recahrge of rs 36 aftr six moths so I hate this thing also in the bsnl tele com company . The tarif of this company is good but not so I should company have to do develop there speed and remove the six moths of rechare I hate these things
