Comparing iPhone's Built-in Call Blocking and Hiya for Scam Call Protection

Scam calls are a persistent nuisance for iPhone users, leading many to seek effective solutions. Apple's built-in call blocking features and third-party apps like Hiya offer distinct approaches to mitigating this issue. This article examines both options to determine which provides superior protection against scam calls.

How Does iPhone's Built-in Call Blocking Work?

Apple's native call blocking features include 'Silence Unknown Callers' and 'Call Blocking & Identification.' 'Silence Unknown Callers' sends calls from numbers not in your contacts directly to voicemail, preventing them from ringing. However, this method doesn't identify or block scam calls; it merely silences them. 'Call Blocking & Identification' allows third-party apps to filter incoming calls, but its effectiveness depends on the app's database and update frequency. (macobserver.com)

What Is Hiya and How Does It Protect Against Scam Calls?

Hiya is a third-party app designed to identify and block scam and spam calls. It maintains a global database of known scam numbers and uses real-time signals to flag suspicious calls. When a call comes in, Hiya checks the number against its database and labels it accordingly, providing users with information about the caller before they answer. (blog.hiya.com)

How Effective Is Hiya in Blocking Scam Calls?

Hiya has demonstrated high effectiveness in identifying and blocking scam calls. In tests, it flagged 87% of confirmed scam calls before they rang, including IRS impersonators and fake warranty renewals. However, it occasionally mislabels local businesses as 'Spam Risk' due to rapid number reuse. (alibaba.com)

How Does Hiya Compare to iPhone's Built-in Features?

While iPhone's built-in features can silence unknown callers, they don't actively identify or block scam calls. Hiya, on the other hand, provides proactive protection by identifying and blocking scam calls before they reach you. Therefore, Hiya offers a more comprehensive solution for scam call protection compared to Apple's native features. (makeuseof.com)

Are There Any Drawbacks to Using Hiya?

Some users have reported issues with Hiya mislabeling legitimate calls as spam, especially from local businesses. Additionally, while Hiya offers a free version, its premium features require a subscription. (apps.apple.com)

How Can I Set Up Hiya on My iPhone?

To set up Hiya on your iPhone:

  1. Download the Hiya app from the App Store.
  2. Open the app and follow the on-screen instructions to enable call blocking.
  3. Go to Settings > Phone > Call Blocking & Identification and toggle on Hiya.

This setup allows Hiya to filter incoming calls and provide scam protection. (blog.hiya.com)

Conclusion: Which Is Better for Blocking Scam Calls on iPhone?

While iPhone's built-in call blocking features can silence unknown callers, they don't actively identify or block scam calls. Hiya offers proactive protection by identifying and blocking scam calls before they reach you. Therefore, for comprehensive scam call protection on your iPhone, Hiya is the more effective solution.
