Hello everyone
I had bought the jio sim on 1 dec 2016 and use it for almost 12 days.
It has fast network .
My average speed is 2 mb per second.it also depend upon ur distance from the tower.it is available free in all over india.you must take aadhar card with you before purchasing it.u must have a 4g phone also.i went in city and my average speed was 15.6 mbp/s. I feel shocked. u must buy it.now there are cheap 4g phones of LYF brand.the offer is valid until 31 march 2017. you will get unlimited net until 31 march 2017 and free voice and video call for life time.if u haven’t purchase yet .than purchase it right now.
