How to block spam calls on iPhone free

You don’t need to pay for premium apps to stop spam calls — your iPhone and carrier already include free tools that work great.

1. Turn On Silence Unknown Callers

Go to Settings → Phone → Silence Unknown Callers.
This sends calls from numbers not in your contacts straight to voicemail.

2. Use Your Carrier’s Free Spam Protection

All major U.S. carriers provide free spam call filtering:

AT&T Call Protect (Free Version)
Verizon Call Filter (Free Plan)
T-Mobile Scam Shield (Free Basic Protection)

These detect and label potential spam before your phone rings.

3. Report Spam Calls

Report spam to FTC (donotcall.gov) or text the number to 7726 (SPAM) — a free service supported by all carriers.

4. Use Free Third-Party Apps

Hiya and Truecaller both offer free versions that identify spam calls without needing a subscription.

AvNexo Tip: Combine iPhone’s built-in Silence Unknown Callers with your carrier’s free spam filter for the most effective no-cost protection.
