Frequently Asked Questions (FAQs)

Will blocking calls from unknown numbers also block text messages from those numbers?

Not necessarily. Blocking a number typically prevents calls, but text messages may still get through. You may need to separately block the number from within your messaging app.

What happens when someone I don’t know calls me after I’ve activated “Silence Unknown Callers” on my iPhone?

Their call will be silenced and sent directly to voicemail. You won’t receive a notification of the call unless they leave a voicemail.

Are there any downsides to using third-party call-blocking apps?

Some apps may collect your data or require permissions to access your contacts. Always review the app’s privacy policy before installing. Some can also impact battery life.

Is it possible to unblock a number I’ve previously blocked?

Yes. You can easily unblock numbers through your phone settings, carrier services, or third-party apps. Find the blocked number list and remove the desired entry.

Does blocking calls from unknown numbers prevent scammers from reaching me altogether?

While it reduces the frequency, it doesn’t guarantee complete prevention. Scammers constantly change their numbers, so blocking one number won’t stop them entirely.

How effective are carrier-provided call-blocking services?

Effectiveness varies by carrier and the specific service. Most offer a reasonable level of protection, but they are not foolproof.

Will blocking unknown numbers affect my ability to receive calls from emergency services?

No. Emergency services and critical alerts should always be able to reach you, regardless of your call-blocking settings.

Can I block calls that are not in my contacts on a landline phone?

Some landline providers offer call-blocking services, such as anonymous call rejection, which blocks calls from numbers that hide their caller ID.

What is “Caller ID spoofing,” and how does it affect call blocking?

Caller ID spoofing is when scammers disguise their number to appear as a legitimate number, making it harder to identify and block them. It’s a cat-and-mouse game.

If I use a call-blocking app, will it block numbers that I do want to receive calls from?

It’s possible if the app incorrectly identifies a legitimate number as spam. Review the app’s settings and blocked list regularly to ensure accuracy.

What if I need to receive calls from certain unknown numbers (e.g., a new doctor’s office)?

Temporarily disable the call-blocking feature or manually add the number to your contacts before the expected call.

Are there any legal considerations related to blocking calls from unknown numbers?

In general, blocking calls from unknown numbers is perfectly legal. However, be mindful of potential exceptions if you run a business and rely on receiving calls from new clients. Review relevant laws and regulations in your jurisdiction.
