Mobile data settings page is blank and carrier shows No Service
I am facing this issue from the afternoon... The carrier service showed No Service and I can't make or receive any phone calls! As per the instructions for solving No Service issue, I have:
1) Restarted the mobile several times
2) Tried force restart too :-(
3) Updated to 12.1 iOS
4) Reset all the default network settings
And when I tried to carry out the step Settings->MobileData->To make data roaming on! I encountered this blank screen inside the Mobile Data settings page. Please guide me...
iPhone 5s, iOS 12.1
