Step 1 of 4 • Open Settings → Phone

Tap the gray Settings icon, then scroll down to Apps → Phone.

Look on your Home Screen for the gray Settings icon (silver gears) and tap it. Inside Settings, touch lower on the screen and slide upward to scroll down to the bottom, then tap Apps → Phone.

🔍 What to look for on your iPhone screen: Gray Settings icon → “Apps” → “Phone”

🏮 Lanny’s pointer tip: “Tap Settings, then touch lower & slide UP to open Apps → Phone!”

👉 Try it now: Tap the gray Settings icon on your iPhone, scroll down (touch lower and slide up), and open Apps → Phone.

💡 Helpful Note: Remember: to scroll down a page on iPhone, place your finger lower on the screen and push upward!

Step 2 of 4 • Find Silence Unknown Callers

Scroll down and tap “Silence Unknown Callers.”

Inside the Phone settings screen, touch lower on the screen and slide upward to scroll down near the bottom until you see the row labeled Silence Unknown Callers, and tap it.

🔍 What to look for on your iPhone screen: “Silence Unknown Callers” row

🏮 Lanny’s pointer tip: “Touch lower, slide UP, & tap Silence Unknown Callers!”

👉 Try it now: Scroll down (touch lower and slide up) and tap Silence Unknown Callers on your iPhone.

💡 Helpful Note: It usually displays “Off” on the right side until you turn it on.

Step 3 of 4 • Turn the switch ON

Tap the switch so it turns green.

Tap the toggle switch next to Silence Unknown Callers so it slides to the right and turns green. Numbers you have never interacted with will now go quietly to voicemail without interrupting you.

🔍 What to look for on your iPhone screen: Green toggle switch next to Silence Unknown Callers

🏮 Lanny’s pointer tip: “Flip that switch green—goodbye robocalls!”

👉 Try it now: Turn the switch on (or leave it off if you are expecting a call from an unfamiliar number today).

💡 Helpful Note: Anyone saved in your Contacts, anyone you have recently called, and numbers suggested in your emails/texts will STILL ring normally!

Step 4 of 4 • Check Recents & Voicemail

Where do silenced calls go?

Silenced calls are never erased! If a legitimate caller (like a new technician or pharmacy) calls from an unknown number, they can leave a voicemail and their number still appears in your Phone app under Recents.

🔍 What to look for on your iPhone screen: Recents (clock icon) and Voicemail tabs in the Phone app

🏮 Lanny’s pointer tip: “Real callers can still leave a Voicemail anytime!”

👉 Try it now: Open your green Phone app and glance at the Recents and Voicemail tabs at the bottom so you know where to check.

💡 Helpful Note: If you are ever expecting a call from a contractor or doctor’s back-office line, you can flip this switch off and back on anytime.
