Receiving calls labeled as "No Caller ID" can be both frustrating and concerning. These calls often originate from telemarketers, scammers, or other unwanted sources. Fortunately, there are effective ways to block these calls on your iPhone.
What Are No Caller ID Calls?
"No Caller ID" calls are incoming calls where the caller's information is withheld, making it appear as if the number is private or unavailable. This anonymity is frequently exploited by telemarketers and scammers to bypass call-blocking measures.
How Can I Block No Caller ID Calls on My iPhone?
Apple provides a built-in feature to help manage these calls:
- Enable Silence Unknown Callers:
- Go to Settings > Phone.
- Toggle on Silence Unknown Callers.
This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions, sending them directly to voicemail. While effective, it may also silence important calls from unknown numbers.
Are There Third-Party Apps to Block No Caller ID Calls?
Yes, several third-party apps offer enhanced call-blocking capabilities:
-
Robokiller: Recognized as a market leader, Robokiller blocks 99% of robocalls and texts.
