Jio is a great thing given by ambanis. When it was lanched providing great strength of data network speed so many people get attracted to it and the main thing it was free for 1 year. Now from I guess april they charged 99rp for the prime membership of 1 year and the two packs 1. 399 for unlimited calling, 100sms per day free and 1gb data free per day 2. 599 it is same as 399 offer just we ger 2gb data free on each day. The people having the sim got the membership by loging on jio application via sim paying 99rp or via paytm payment. Its called dhan dhana dhan scheme. The most impressive thing is the sim gets activated with in 5 mins by just giving your adhaar card no and you to give your finger print authontication. You can have only one sim for one adhaar card no as it fetches all the information about the sim holder which gets recorded on their sever and get displayed on over jio application. Jio application gives you detailed information about the sim with sim no, balance, active plans, its expiry , used data and sms per day. You can get the new plan activated through this application. Now a days many users facing some speed problem in data and this is bacause lots of users using the services, users grawing day by day. Best brand as compared to another brands. Ambani has said as we will provied 20% more data than others. Thank you
