We all know about Relience JIO's free Happy new year offer where we're getting free 1 GB data each day. But after March we have to buy packs which are not even competitive i mean for a person to use mobile data it's kind of expensive. Free call & SMS (If enough connection port) available is ok but what about data. They have to come up with some solid plans to sustain. So my question is which is the next big thing (4G) - Airtel/Idea or Vodafone?
