How to stop spam calls
Four things genuinely cut down spam calls, and they work best stacked on top of each other: the call-silencing setting already built into your phone, your carrier's free spam filter, the National Do Not Call Registry, and deciding who answers the calls that still get through. Here is each one, in plain steps.

How do you stop spam calls?
Stack four layers, cheapest first: turn on the unknown-caller setting built into your phone, switch on your carrier's free spam filter, add your number to the National Do Not Call Registry at donotcall.gov, and then decide who answers the calls that still come through.
There is no single switch. Each layer catches a different kind of caller, which is why people who only do one of them usually feel like nothing changed. The first three are free and can be done this afternoon.
- Layer 1 — your phone's own settings. Silencing or screening unknown numbers is free and takes about a minute. The exact menu names differ by phone, so we wrote them out for each one below.
- Layer 2 — your carrier's spam filter. AT&T, T-Mobile and Verizon all offer free spam labeling and blocking through their own apps, on top of whatever your phone does. Turning both on is not redundant — they use different data.
- Layer 3 — the National Do Not Call Registry. Free, run by the FTC, and it never expires. It covers cell phones. It works on telemarketers who follow the law, and not on the ones who don't.
- Layer 4 — something that answers. The first three layers label a call or send it to voicemail. None of them finds out who is calling or what they want. That is the gap screening fills.
Why am I getting so many spam calls?
Because placing them costs almost nothing. One computer can dial thousands of numbers an hour, so the caller only needs a tiny fraction of people to pick up for the whole operation to pay.
Your number gets onto call lists in ordinary ways: a sweepstakes entry, a warranty card, a public record, a data broker that bought a list from another data broker. Once it is on one list, it spreads to others.
The caller ID you see is often false. The FCC calls this spoofing, and "neighbor spoofing" — making a call look like it is coming from a local number — is common, because a familiar area code gets answered more often than an unfamiliar one.
Answering can make it worse. A live answer tells the dialer the number is real and reachable, and a number that answers is worth more on the next list than one that doesn't.

How do you stop robocalls?
Robocalls — the ones that play a recording — are best handled by your carrier's free spam filter together with your phone's unknown-caller setting, because the two of them stop most automated dialers before you ever hear a ring.
Most sales robocalls are already illegal. The FTC states it plainly: if a robocall is selling something, it is illegal unless the company has written permission, directly from you, to call you that way. You owe that caller nothing — not politeness, not an explanation.
- Don't press a button to be removed from the list. Pressing 1, or saying anything at all, confirms a real person is on the line.
- Don't call back a missed call you weren't expecting, even if the number looks local.
- Report the call. DoNotCall.gov has a short form for unwanted calls. ReportFraud.ftc.gov is the place to go if money was lost.
- Reports matter more than they feel like they do — they are what feed the lists that every carrier filter and blocking app draws on.

How do you stop unwanted calls on a cell phone?
Cell phones have the strongest free tools, and they live in the phone's own settings — one screen that either silences numbers not in your contacts or filters calls your carrier has already labeled as spam.
The menus are named differently on each kind of phone, and they move between software versions, so guessing from a generic guide usually wastes ten minutes. We wrote out the current steps separately for each platform — the links are further down this page.
A cell phone can also do something a landline mostly can't: forward its calls somewhere else. That is the plumbing a screening service uses to answer on your behalf, and it is a standard carrier feature rather than an add-on you buy.
How do you stop scam calls, not just spam?
Blocking known spam numbers is the easy half. Scam calls are harder, because scammers buy fresh numbers constantly — so a call from a number nobody has reported yet arrives looking perfectly clean.
That is the honest limit of every blocklist, carrier filters included: a list can only know about a number somebody has already complained about. The call that gets through is, almost by definition, the one from a number that isn't on any list yet.
Impostor scams are the largest category the FTC tracks. People reported losing $3.5 billion to them in 2025, and nearly one in three fraud reports that year was an impostor scam — someone pretending to be a bank, a government agency, or a company you deal with.
The phone is the doorway for the biggest losses. Of the older adults who reported losing $10,000 or more to a business or government impostor in 2024, 41% said a phone call was the first contact.
So the useful question is not only "is this number on a list" but "what does this caller actually want" — and answering that takes something willing to pick up and ask.

Where Gini fits in
Gini answers the calls you would rather not answer. Your calls are forwarded to Gini using the call forwarding your carrier already supports; Gini picks up unknown callers before your phone rings, works out what they want, and passes through the ones that matter.
It answers instead of labeling
Most tools tell you a call is probably spam and let it ring anyway. Gini picks up the unknown caller first, so automated dialers and obvious scams are dealt with before your phone makes a sound.
It keeps listening after you answer
Some scammers are real people who sound legitimate and talk their way past any screen. When a connected call turns risky — a request for a verification code, pressure to act right now — Gini raises a warning while you are still on the line.
Texts and email get watched too
Gini scans your texts and your Gmail and flags the ones that look like scams. It does not write or send anything for you — you decide what to do with a flagged message.
Setup uses standard carrier call forwarding, so there is no new number and no switching carriers. What people tend to describe afterwards is a quieter phone: far fewer strangers getting through, and a voicemail box that stops filling up with junk. There is a 7-day free trial, and current plans are listed on the pricing page.
What do you do when the spam calls never seem to stop?
Work the four layers in order, and change how you treat calls you don't recognize — when your phone is ringing all day with strangers, the habit matters as much as the settings.
- Let unknown numbers go to voicemail. A caller with real business leaves a message.
- Don't confirm anything to a caller you didn't expect — not your name, not your address, not even "yes".
- Block and report each one. Number by number it feels slow, but reports are what keep the shared spam lists current.
- If a caller claims to be your bank or a government agency, hang up and call back using the number printed on your statement, your card, or the agency's own website.
- If you are setting this up for a parent, do it on their phone with them watching. The settings take a few minutes and they will need to know why calls stopped ringing.
Frequently Asked Questions
Is there a way to stop spam calls completely?
No tool stops every call, and anything promising that is overselling. What is realistic is far fewer: the built-in settings and your carrier's filter take out most automated dialers, the Do Not Call Registry takes out telemarketers who follow the law, and screening handles the unknown callers left over. Together that is the difference between a phone that rings all day and one that mostly rings for people you know.
Does blocking a number stop the calls?
Blocking stops that exact number, which helps with a persistent caller. It does less against operations that rotate through new numbers, because the next call arrives from a number your phone has never seen. Block anyway — and report it, since reports are what put numbers on the shared spam lists.
Why do I get spam calls from my own area code?
That is called neighbor spoofing. The FCC describes spoofing as a caller deliberately falsifying the information sent to your caller ID, and making a call look local is one of the most common versions, because people answer familiar area codes more often. The number on your screen may belong to a real neighbor who has nothing to do with the call.
Does the Do Not Call Registry stop spam calls?
Partly. It is a legal requirement for telemarketers who follow the rules, so the legitimate sales calls thin out within about a month. The FTC is direct about the limit: the Registry does not block calls, so being on it will not stop scammers making illegal calls. Register anyway — it is free and takes two minutes — but expect it to solve one half of the problem.
Should I answer and ask to be taken off their list?
No. With an illegal robocall there is no list to be taken off, and answering or pressing a key confirms that a real person picked up, which makes your number more valuable to the next caller. Hang up without speaking, then report the call at DoNotCall.gov.
Are spam call blocker apps worth it?
They do one job well — matching incoming numbers against a database of numbers other people have reported — and the free carrier apps do that job at no cost. What none of them do is find out what an unreported caller wants. If your problem is volume from known spam numbers, the free tools may be enough. If your worry is the convincing caller who gets through, you need something that answers.
How do I stop spam calls on a landline?
Landlines have fewer built-in options, so the levers are the Do Not Call Registry, whatever blocking your phone company offers, and a device or service that screens calls before the phone rings. We cover the landline case separately on our landline protection page.
I get 20 spam calls a day. Where do I even start?
Start with your phone's unknown-caller setting, because it is the one change that quiets things down today — unknown numbers go to voicemail instead of ringing. Then turn on your carrier's free spam filter, then register at donotcall.gov. If calls are still getting through after that, the remaining ones are the numbers no list knows about yet, and screening is what addresses those.
