I have an iPhone SE 2020. About 2 months ago all unrecognised numbers started going straight to voicemail. I have tried so many things to stop thick but no joy. I am missing important calls from hospitals etc because of this. Any ideas?
In iOS 13 a new feature called Silence Unknown Callers could mean that all calls from people not in your Contacts will be going straight to voicemail. Check this by opening Settings > Phone and scrolling down to Silence Unknown Callers. Good luck!
Thought it was too easy, @Nelly4 😆
Just to be sure, no harm in toggling the setting - set to on for a few minutes, then set it back to off.
Here's an article that covers a number of ways this could happen, and corrective actions you may like to try: https://www.macworld.co.uk/how-to/stop-iphone-calls-voicemail-3521926/
