I bought jiofi on a very simple basis. it is very well designed and looks beautiful in its common black colour.the speed it gives in every corner of house and city is astonishing we can say reliance has done a very good job on its range and speed services we have very well known shops selling it and free service until 6 months speed becomes a little low after 1 gb data limit but it is tolerable and fast compared to others the battery life is very impressive as it lasted a whole day for me. a good deal we can say
