I have updated iPhone 8 with iOS 14 since then I cannot make calls or receive none. Only when connected to WiFi, calls go through. After all reset try's, done full updated using iTunes for 14.2. Still same. No improvement. Only way to make calls is to connect to WiFi or switch to 2G.
Similar issue with my older phone when updated with iOS 13, it ruined WiFi. I had to be like with in a meter distance of router to use WiFi.
Now I wonder if it’s really a bug or intended design to get users replace with new phone.
