I have activated jio preview offer in my redmi note 3 a month ago using old My Jio app. it was hard to get a Jio sim from reliance mini 40 km away from my house. He refused to give sim, told that I will never get unlimited free offer, and sim will stop working. However it's all fine now. yesterday I was sitting with my friends and suddenly local jio dealer(who never agreed to give a sim before) came and ask for our photo and documents with code. he didn't want to see any mobile phone. It was just an opportunity for us. I know how can generate the code in every 4g phone. within 2 hours 10 set documents ready with code and sent to him. we are about to get jio sim cards today.
