Network is not so good in my area. Voice calling is not reliable.the other person cannot hear the voice clearly 70% of the time.from few days have to redial number atleast 3 times to get connected amd few times the volte gets diaconnected automatically and looks no bars in signal bars. Have to restart the device or remove and put the sim back again to get it back on track again. Hope it gets better in coming days when it becomes payable to users. Or users wont carry a jio sim for such issues when they paying for it.
