I flashed my device yesterday with latest firmware available on samsung website for my Samsung j6 now when I have inserted a properly a working sim card in my Samsung j6. signals are showing full. But when I try to make call It says network is not registered. Then I went to settings and I tried to choose my network manually as well as automatic, but it says "error in finding network" for manual option and "unable to connect try later" for automatic option. I have also tried to restart and insert my sim again and all basic troubleshooting but nothing is working. Please help
