Iam am using dual.sim phone with sim 1 as jio and sim 2 as airtel.
I always use my sim 1 for calling.
But when I try to call from sim 1, thus true caller connects the call automatically through sim 2. I dont know how this happens. I reinstalled it but this same problem happens.
And one more thing is that, when some number call me, this my phone doesnt rings. Although my phone is in general mode, my phone doesnt rings. When I unliacks my phone many missed calls will be there.
I got fed up with it and now I uninstalled it.
Bad service.
