Following rate cuts by major operators Airtel and Idea Cellular, Vodafone has came out with promotional schemes offering up to 67% more data of 2G, 3G and 4G services at same price during this month.

"Under the revised data benefits, the 3GB 3G/4G monthly recharge pack, which was earlier priced at approximately Rs 650 will now offer 5 GB data, an increase of 67%," Vodafone said in a statement.

Similarly, the Rs 449 scheme of Vodafone for 3G/4G will now offers 50% more data by increasing the data benefit to 3GB from 2GB and the Rs 999 3G/4G pack will now offer 10 GB data, which is 54% more benefits.

"It will also make the Internet more affordable for customers who use mobile internet in a limited way and encourage first time users to come online," Vodafone said in a statement.

The development comes within a fortnight after Airtel and Idea slashed data tarrifs.

So, we can see it as effect of Reliance JIO, although it is still not yet launched commmercially and whomesoever is using , is using free internet preview pack.

Brother , yes I think it is effect of Reliance Jio way before even its launched. But what the hell, even after the increased data value, they are costly. They were over priced earlier and still very high priced. They are just exploiting Indian customer by such exorbitant data prices. All these major players ie. Idea, vodafone and airtel have I think some kind of internal pact to keep data prices so high with high margin. And smaller player like Telenor, Docomo, Aircel who provide better pricing, can't make much changes as they don't have big enough share in market to affect these giants.

I think RJIO will definitely help customers in terms of more affordable data .
