    1

    Turn on Silence Unknown Callers (the big one)

    ~43s
    Open Settings → scroll down to Phone (or "Apps" → Phone on iOS 18 and 26) → "Silence Unknown Callers" → turn it on. From now on, any caller who is not in your Contacts, not in your recent outgoing calls, and not in Siri Suggestions (people you have messaged or emailed) will not ring your phone. They go straight to voicemail. You still see a missed call notification. So you know they called. They just cannot interrupt you. Real callers leave voicemails. Spammers usually do not.

    Warning

    If you are expecting a call from a number you do not know (a doctor, a delivery driver, a job interview), turn this OFF for the day. Then turn it back on. Important real calls do get silenced sometimes — the trade-off is fewer spam interruptions.

    2

    Turn on Call Identification (Carrier-level Scam Likely)

    ~35s
    All four major U.S. carriers — Verizon, AT&T, T-Mobile, Spectrum Mobile — now show "Scam Likely" or "Spam Risk" on incoming calls they identify as fake. This is free and on by default for new accounts but sometimes turned off on older accounts. To check: Verizon — open the Verizon Call Filter app (free), tap Settings, turn on "Spam Filter." AT&T — open the AT&T ActiveArmor app, turn on "Block likely spam." T-Mobile — open the T-Mobile Scam Shield app, turn on "Scam Block." Once on, calls labeled Scam Likely either show a warning when they ring or get blocked entirely (your choice in the app).
    3

    Block individual numbers as they call

    ~41s
    When a spam call comes through that is not caught by the first two filters, block the number manually. Open the Phone appRecents → tap the small "i" in a blue circle next to the number → scroll down → tap "Block this Caller." Confirm. That number can never call or text you again. You can also block from Messages — tap the contact name at the top → tap the info icon → Block this Caller. To see your full block list later: SettingsPhoneBlocked Contacts.

    Quick Tip

    Quick Tip: Most spammers use a different number every call (called number spoofing). Blocking one stops that exact number but not the same person calling from another. Combine this with the other steps for full coverage.

    4

    Install a call-blocking app (the boost)

    ~39s
    Free third-party apps maintain a huge crowdsourced database of known scam numbers and block them before they ring. Two work well in 2026: Hiya (the official app for Verizon Call Filter) and Truecaller. Install one from the App Store. Open it, sign up with your phone number, then turn on the "Call Blocking & Identification" permission when iPhone asks. After that, the app does its work in the background. Whenever a known scammer calls, you see "Scam Likely" instead of a phone number — and the call usually gets silenced.

    Warning

    Avoid free call blockers that ask for your contact list. The reputable ones (Hiya, Truecaller, Robokiller) work fine without uploading your contacts. If an app demands contact access on first launch, delete it.

    5

    Check your voicemail for important silenced calls

    ~36s
    Once a day, check your voicemail and the "Missed Calls" list in the Phone app. Most real callers leave a message. If you see a missed call from an unknown number with no voicemail, it was almost certainly spam — ignore it. If a real caller (a doctor, a relative) was silenced and did not leave a message, they will try again. You can call them back if they show up in Recents.

    Quick Tip

    Quick Tip: Set up a custom voicemail greeting that says "Please leave a name and number so I can call you back." This trains real callers to leave a message and weeds out spammers, who rarely leave anything.

    6

    Add yourself to the Do Not Call list

    ~22s
    The FTC runs a free national Do Not Call Registry. Real businesses (telemarketers, charities) must remove you within 31 days. Scammers ignore it, but the registry catches every legitimate sales call. Sign up at donotcall.gov — takes 30 seconds, only need an email address. You can add up to three phone numbers per email. Once registered, real telemarketing calls drop noticeably within a month.
    7

    Report a scam call to make it stop for everyone

    ~25s
    Reporting a scammer helps the FTC and FCC track them down. Two minutes per report. (1) ReportFraud.ftc.gov — fill out the short form. Include the number, what they said, and when. (2) Your phone carrier — text "7726" (spells SPAM) and forward the scam number. Carriers use these reports to add numbers to their Scam Likely databases. (3) The FCC at fcc.gov/complaints if a robocall violated rules (no consent, fake caller ID).

    The FCC estimates Americans get 33 spam calls per person per month. Robocalls, scammers pretending to be the IRS, "your car warranty is about to expire". They all use spoofed phone numbers that look like real local numbers.

    iPhone has three free settings that, used together, block almost all of them. Add a free third-party app like Hiya or Truecaller and you can knock spam calls down to maybe one a week. The whole setup takes 5 minutes and costs nothing.

    This guide walks through the three iPhone settings, the call-blocking apps that work with iOS in 2026, and what to do when a real number you do not recognize gets blocked by accident.
