It's an lg stay 5 I am not able to change my preferred network mode it says network mode 22.. Network operators are not working either. when I try to make calls, my phone thinks it’s in Airplane mode and “ radio off “ appears there. I have no service unless it's Wi-Fi. It's not the SIM card because I tried it another phone and the *#*#4636#*#* I've already tried but nothing works it just all a sudden did this
