UNKNOWN NAME Showing up instead of actual phone number
The cell phone carrier sends this information, so I would do in order:
- check for carrier setting update
- Check for iOS update
- Test with a couple numbers (delete the number from contacts if needed)
- If it’s systematic, restart the device and update it.
- If it’s not systematic, call your carrier for support.
In the end, carrier support may be needed to validate why this happens if it’s not a simple need to update or restart and retest.
