Jio the brand which is launch in 2016 with unbelievable offer of 3 months free of cost use in all formats after 3 monts jio has also give new year offer that he extended the free of cost offer for another 3 months to march31, now about my experience I am also a jio customer from 3 months . after three months use I am not a satisfacted customer because their network coverage is very poor, for download a film or any videos the time takes upto 30min to 1 hrs for download the content. and when talk about the calling when I try about 10 times then a call connects and between the call sometime the call has also been disconnected due to poor network. only the good thing of jio is that they give sim in free of cost.
