This is worst phone in this price range, however it is 4g phone and support jio sim, but its network is not as good as 4g phone should have , ram is 2gb that is quit good, rom is also good, its camera quality is average and I think worst in this price range, its processor is also not good and it get hanged in barly handle 2 to 3 apps , looks is good but problem lies in quality , het heat in just 10 minute run, and cool pad is much better in this price range I think , the worst thing of this phone is its poor battery.
