Call failed on outgoing calls
on iPhone 8 it is not possible to make outgoing calls, although incoming calls and cellular network are working properly. Tried everything from rebooting, turning on and off airplane mode, resetting network settings
When I set up as a new iPhone the issue did not occur so it seems to be software related. Apple support says I have to set up my phone fromscratch but I do not want to lose my messages, apps and everything else like apps and so on...
Any tips what else to do?
