I received the message and I went to the reliance digital store with my adhar card to do the formality. I received the confirmation after 24 hours. Maybe they want to eliminate the users who were using false identity . The procedure is simple , You need to carry your orignal adhar card and your jio number with you. You get a otp on your phone ,give that to the representative of jio and then they do the finger print scanning after taking your adhar card . Thats it , it takes around 5 min max. Its the same procedure for buying a new sim also (atleast for prepaid for any network).
