Hi friends, I am a previous customer of vodafone postpaid and some months back I have ported my number from vodafone to BSNL. The reason why I change to BSNL that it has the number one network coverage in all over India. We can trust BSNL and travel anywhere with out any loss of network coverage. Before the entering of GIO BSNL provided good tarif plans than any other service providers. Customer service is nice and the charges are affordable .
