I was a vodafone pre paid customer and their plans were so costly that one have to suffer with costly call rates and costly internet plans. I used vodafone 3g for a mpnth and it was just awful experience for me as there network is always out of coverage even though vodafone 3g was availible in my city but when ever I complained to customer care they just tell me to do the settings again but after some time it was again like wanna throw my sim some where else.
They charge for 3g equal to the airtel charges but ever after such high rates of rs295 1gb, service was not upto the point.
