After the launch of Reliance JIO sim card and their undigesting offers like FREE CALLING and FREE INTERNET made people crazy and increased demand of Reliance JIO card and vice versa for the other telcom companies like IDEA AIRTEL etc.
But after that Vodafone introduced SUPERNET 4G for their Customers with a high speed of 2-5 mbps.
Also,
Vodafone will provide free upgradefor 4G along with high speed 4G sim with 2GB data free.
