Spam calls are relentless, and answering just one tells the robocallers your number is live. You can’t stop every call, but you can cut the volume down hard with a few settings and habits. This guide covers what actually works, why you get so many, and the mistakes that make it worse.
- Turn on Silence Unknown Callers so strangers go to voicemail.
- Block the repeat offenders from your recent calls.
- Report junk to 7726 (SPAM) so your carrier can act.
- Never press a key or call back — it confirms your number is real.
The steps that work
Start with the built-in tools, then layer on carrier and app filtering. Most people cut the majority of spam with the first two steps alone.
Switch on Silence Unknown Callers (iPhone: Settings › Phone; Android: Phone app › Settings › spam and call screen). Block numbers that keep calling from your recents. Report junk by forwarding the text or number to 7726. And add a call filter from your carrier or a reputable app to label and screen the rest.
Why you get so many
It helps to know what’s driving it, because a couple of the reasons are things you can control.
Your number leaks through data breaches and sign-up forms. Caller ID is spoofed to look local so you’ll answer. Answering or pressing a key marks your line as active, which means more calls. And it’s dirt cheap to dial millions at once, so there’s no reason for them to stop.
Habits that keep it down
The settings do a lot, but your own habits decide whether the flood grows or shrinks.
Don’t answer unknown numbers, let voicemail screen them. Never press a key to “opt out,” that just confirms you’re real. Don’t call back a missed unknown number. And report junk to 7726 so carriers can trace and block the source. If you’re worried about who’s calling a child’s phone, a call log shows you every number, not just the ones that got through.
Common questions
Will “Silence Unknown Callers” make me miss important calls?
It can, if a new doctor or delivery driver isn’t saved. They still leave voicemail and show in recents, so skim those once a day. Save numbers you’re expecting first.
Does blocking a number actually stop the calls?
It stops that number, but spammers rotate through many spoofed numbers, so blocking alone won’t end it. Combine it with silencing unknowns and carrier filtering.
Is it worth reporting spam to 7726?
Yes. Forwarding junk to 7726 feeds your carrier’s spam detection, which helps block the source for everyone. It takes seconds.
Should I answer to tell them to stop?
No. Answering or pressing a key confirms a live number and usually brings more calls. Let it go to voicemail.
How do I know who’s really calling my child?
A call tracker logs every incoming and outgoing number, so you can spot an unknown caller or a pattern. See our guide to looking up unknown numbers.
You won’t kill spam calls entirely, but silencing unknowns, blocking repeats, and reporting junk will quiet your phone dramatically, as long as you never confirm you’re real by answering or pressing a key. Get started free, and read our guides to blocking spam texts and blocking unknown callers.
