sgopalaswamy , via OnePlus 6 , Sep 21, 2020 : I have a one plus 6 with 2 Jio sim cards. Most of the time when someone calls me, they get a message that my phone is switched off. And when I try to send sms, the messages don't go out. I tried searching online forums but couldn't get any resolution. The Jio network is my area is good as my neighbours are able to get good reception. I see 87db on my signal strength and almost all bars are up. I have to restart my phone a couple of times for it to start taking and making calls again.
