I would check your settings in Focus since some of the features (if you use it) will mess up the iPhone
Here's a more detailed breakdown of potential causes and solutions:
1. Check Focus/Do Not Disturb Settings:
- Do Not Disturb:
- Ensure it's not enabled, as this will silence all notifications, including incoming calls.
- Focus Modes:
- If you're using Focus modes (like "Do Not Disturb" or other custom modes), make sure they are off or that the "Phone" app is allowed to send notifications.
2. Check "Silence Unknown Callers" Setting:
- This feature, found in Settings > Phone, can send calls from numbers not in your contacts directly to voicemail.
- If enabled, consider disabling it to ensure you receive calls from all numbers.
3. Verify Call Forwarding:
- Check for any active call forwarding settings, as this will route calls to another number instead of your iPhone.
- If found, disable call forwarding.
4. Update Software and Carrier Settings:
- Software Update: Ensure your iPhone's iOS is up to date, as bugs can sometimes cause call handling issues.
- Carrier Settings: Update your carrier settings to the latest version.
5. Other Potential Issues:
- Airplane Mode: Make sure airplane mode is turned off.
- SIM Card Issues: Check if your SIM card is locked or if your account is suspended.
- Bluetooth: Ensure Bluetooth is turned off when not in use.
- Network Coverage: Ensure you have good network coverage.
- Contact Carrier: If none of these steps work, contact your mobile carrier for further assistance.
