Airtel, jio, Vodafone Idea Volte not working.
My problem is that as jio Airtel Vodafone has launched it's Volte services but this phone is not supporting it. When I try to make a video call by simply dialing a number of same operator over other phone it doesn't support video calling. I want to know why still it's not supporting network provider supported Video call service. I had used Sumsung, MI, Nokia, 1 plus handset and for my surprise they all support Video call volte but not this phone... Please help me how to fix it and if I want to make Video call on volte how can I do that? Thanks.
