Hi nash156,
The following steps address what you're describing specifically, and should provide a solution:
- "Turn Airplane Mode on and off. Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off.
- Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's off. Learn how to use Focus on your iPhone or iPad.
- Check for any blocked phone numbers. Go to Settings > Phone > Blocked Contacts.
- Check Call Forwarding. Go to Settings > Phone > Call Forwarding and make sure it's off.
- Check Silence Unknown Callers. Go to Settings > Phone > Silence Unknown Callers. If the setting is on, a caller must be listed in your Contacts or Recents. Or they must have shared their number in Mail or sent you a message using that number in order for their call to go through. Add their number to Contacts to ensure the phone rings. Calls from some third-party apps might not go through."
