Do you know when jio was not there.?
Airtel, idea, vodafone give very expensive offers like-₹100 28D 512MB, but now ₹29 28D 512MB. You notice there is very difference between them. They change this offers because JIO was giving very very cheap offers as compare to airtel, idea, vodafone. So, they change their offers and copied JIO and give offers like JIO offers.
Do u know.?
When the JIO was released JIO give a offer named JIO PRIVIEW OFFER that give 3 months unlimited internet and after some months they again release a new offer named JIO WELCOME OFFER that gives us 4GB/DAILY Internet till 31, dec 2016 and they again launched a new offer named JIO HAPPY NEW YEAR OFFER that gives us 1GB/DAILY for 3 month. These offers was free no charge was obtained by TEAM JIO. So, after coming JIO there are veey changed to our DIGITAL INDIA. I espically thanks to mukesh ambani who launched that JIO company.
