I had bought jio sim in black for 500? form an retailer it took 5 days to start.it was started after my fingure prints where scan in 7 hrs it is haveing good speed in night in day its around 700kbps but youtube runs so smooth without any buffering nice to have but friend jio is giving only 4gb data daily that can be use on same day of further day that is good policy othere wise after 4 gb it is giving 70 kbps speed that also good to surf facebook, whatsup, twitter, intagram easily overall I am stisfied by paying 500 ? it is also a good option to take sim insted of standing in line in this hot summer.
