I am a vodafone punjab user but I disagree with its network performance . I am with vodafone just because of its attractive offers otherwise in terms of network it is not pretty cool .
I think vodafone might be the only carrier which has more users than other carrier in india . Talking about its call quality it is not upto the mark and talking about internet its delivers some kind of connectivity issues . Overall it delivers good offers but with the view of network it might shows some kind of problem with it
