I’m using BSNL from several years, The network coverage of BSNL is all over the India from east to west and from north to south is awesome, you will see the network of bsnl everywere all over India, I also use bsnl landline in my house, and I can talk from 9pm to 7am to anyone from any side of the country totally for FREE! But this offer is not available in the mobile phones. This is the best part of bsnl, I refer it to everyone all over the country. The services are very cheap and affordable for every person. And I also use bsnl 3g in my phone which is very cheap and fast comparing to any other cellular service. Bottom line, Highly recommended to everyone.
