I am using various mobiles since 16 yrs. and my experience is that Sony mobiles are worst mobiles(take any model). never ever go for mobiles of Sony. After sell service is also pathetic .
Yes it supports Jio sim n all apps, only HD video call that you can’t make but you can receive video calls from others it is updated to marshmallow 6.01. I just bought z3+ dual yesterday. But the heating issue still there when u used video cam.
Hope it help u.
