I used vodafone mobile number. Internet speed of 3g and 2g good but very costly as compared other network. In Urban areas they have provided good network. But in some rular areas they not provided good network. No roaming free in maharastra of mumbai users. That is big negative point of Vodafone. Calling rates is very high. Vodafone network is only for reaches people not for middle class and others.
I suggest they improving there internet and calling network in Ruler areas and decreses there calling and internet rates.
But they provided very good custmer service. That is one of the good positive of Vodafone.
