The new rates for pay-as-you-go (PAYG) prepaid and postpaid users are 4 paisa per 10KB, as compared to 2 paisa per 10KB charged earlier.
The company had in November last year reduced the rates by up to 80 percent to 2 paisa per 10KB, from 10 paisa per 10KB.
When contacted, a Vodafone spokesperson said: "Vodafone following its price change in November 2013 has revised its mobile Internet charges for Pay-as-You-Go (PAYG) users. At 4p/10KB, Vodafone still offers most attractive and lowest standard mobile Internet charges in the industry for pre-paid and post-paid customers. This is applicable to both 2G as well as 3G customers."
The Vodafone spokesperson added that this change to mobile Internet rates for 2G and 3G subscribers is applicable across all circles but is being rolled out in a phased manner.
The company had said in November last year that as part of its strategy to 'democratise' data, Vodafone was educating current and potential users about how Internet can add significant value to them.
As per FY'14, Vodafone India logged in 125 percent year-on-year increase in data traffic. The company had 52 million data customers in the country, with 7 million of them 3G data users.
