Unwanted calls, including spam and robocalls, are a persistent nuisance for iPhone users. Apple provides built-in call blocking features, while third-party apps like Hiya offer additional protection. This article examines how Apple’s call blocking compares to Hiya, and why Robokiller may be a more effective solution.
How Does Apple’s Built-in Call Blocking Work?
Apple’s native call blocking allows users to silence calls from unknown numbers, sending them directly to voicemail. This feature is accessible via Settings > Phone > Silence Unknown Callers. While it reduces interruptions, it may also divert legitimate calls from unknown numbers. (makeuseof.com)

Users can customize block and allow lists to manage calls more effectively. (apps.apple.com)
How Effective Is Hiya in Blocking Unwanted Calls?
Hiya processes over 1 billion calls daily worldwide, flagging suspicious behavior before a number becomes widely reported.

However, it occasionally mislabels local businesses as "Spam Risk" due to rapid number reuse. (alibaba.com)
