Why iPhone not showing caller ID for incoming calls?

There are several reasons why incoming caller ID may not be displayed:

  • The caller has chosen to hide their identity: This is often for privacy reasons and can also apply to scammers or telemarketers.
  • The caller's phone or network has caller ID blocking enabled: If the call shows as "Unknown" or "Unknown Caller," this may be the reason.
  • Network settings may have an error: This could result in the call being labeled as "Unknown Caller."
  • The carrier is not transmitting the caller's information: If the carrier fails to send this data, the call may appear as "Private Number."
