Jio give us great offers only for sell the jio sim.but offers are not work properly .I get 1 gb internet daily but during evening the internet speed become very slow .unlimited calls are given only for show, calls are not connect properly always .cellular data is very boring .downloads are not very smooth in this 4g sim.my family members are not happy with this sim, though it is 4g.3g works better than jio 4g.i refer you not to buy this sim. I request jio authority to improve it’s connection.Thanks for read my little review.
