Jio was a nice concept but when I heard its giving free unlimited 4g than I little surprised because if reliance has lots of money why the company not using this money to welfare of poor people perhaps giving free 4g . all people are using this because in india when we heard free we doesnot realize what its effect to end . and I reserch on it and found that when we buy a jio sim we have to give a bar code by our phone , its mean we are giving our phone emai number to company which mean our all details going there , at the end of jio free service we have to pay it. By losing our phone because if I took jio sim in slot one anf try to put it on slot it its going blocked . if you do not believe in me then try to reboot your phone all things will be clear and your smart phone will be a box. We are doing buisness with Asia’s no 1 rich people. If you are looking to buy it do try to think about it.
Good luck.
