I bought the reliance jio sim in the reliance showroom waiting for 2 to 3 hours I thouht it will be nice and work nicely but there is no call fecility provided by jio when I call others then it is saying all the lines are busy. Also the internet access they said is 4g network but the apped comming for my mobile is 2g and the other problem is if we insert that sim card in a slot then that slot anly works for jio. So plese dont use it. I am suffering with it
