Reliance JIO is the LTE mobile operator in India.it launched his service in India on 5 September 2016.they main focus how they can attract customer and they start testing his network .they provide free JIO service in many city by using wifi and it works well. I also used his service inJodhpur by using his public wifi free of cost JIO service and I found that it is very good network at that time, it all happen before JIO launched .
finally they launched his service in all over the India and THEY PROVIDE FREE DATA AND OTHER SERVICE FREE OF COST FOR THREE MONTHS BY THE NAME OF WELCOME OFFER.THEN PEOPLE DIE TO GET HIS SIM .CUSTOMER STAND IN A QUE FOR GETTING THE JIO SIM.
I am also user of jio sim and I am quit happy with his service.
BEST OF LUCK JIO.
