"Robocalls are the number one complaint I hear from seniors in the Venice area. Most people don't know that their phone and their carrier already have free tools built in to stop them — they just need to be turned on."
⚡ Quick Answer — Do These Right Now
iPhone: Settings → Phone → Silence Unknown Callers → ON
Android: Phone app → three dots menu → Settings → Caller ID & Spam → Filter spam calls → ON
All carriers: Call or text your carrier to enable their free spam blocking — details below.
Americans received over 50 billion robocalls last year. That's roughly 150 per person. If it feels like your phone rings constantly with numbers you don't recognize, you're not imagining it — and you're not alone. The good news: there are several free, built-in tools that dramatically reduce robocalls without paying for any app or service.
I'm going to walk you through every method, starting with the most effective. Work through these in order and by the end you'll have cut your robocalls by 80–90%.
⚠️ Important: What Robocallers Want
Before we fix this, understand one thing: never press any number when a robocall asks you to "press 1 to be removed from our list" or "press 2 to speak to an agent." Pressing any key confirms your number is active and gets you added to more lists. The only right move is to hang up immediately.
Method 1: Silence Unknown Callers (iPhone)
This is the single most effective robocall fix for iPhone users. When enabled, any call from a number not in your contacts, recent calls, or Siri suggestions goes straight to voicemail — silently. Legitimate callers leave a voicemail. Robocallers don't.
1
Open Settings
Tap the gray gear icon on your home screen.
2
Tap "Phone"
Scroll down until you see the green Phone icon. Tap it.
Settings → Phone
3
Tap "Silence Unknown Callers"
It's about halfway down the screen. Tap it to open the setting.
Settings → Phone → Silence Unknown Callers
4
Toggle it ON
Tap the switch so it turns green. You're done. Unknown callers will now go straight to voicemail.
💡 Important Note
Make sure any doctors, pharmacies, or businesses you deal with regularly are saved in your Contacts — otherwise their calls will also go to voicemail. This is easy to fix: just add them as contacts and they'll ring through normally.
Method 2: Filter Spam Calls (Android)
🤖
Android: Google's Spam Filter
Works on most Android phones with Google's Phone app · Takes 60 seconds
Google's Phone app has a built-in spam filter that identifies and blocks known robocall numbers automatically. It's updated constantly as Google identifies new spam numbers. Most Android phones have this already — it just needs to be switched on.
1
Open the Phone app
Tap the green phone icon — the one you use to make calls.
2
Tap the three dots (⋮) in the top right corner
This opens a small menu. Tap "Settings" from the menu.
3
Tap "Caller ID & Spam"
You'll see this option in the settings list.
Phone app → ⋮ → Settings → Caller ID & Spam
4
Turn on "Filter spam calls"
Toggle the switch. Spam calls will now be automatically declined and logged — you'll see a "Spam" label in your recent calls list.
💡 Samsung Users
If you have a Samsung Galaxy, open the Phone app → tap the three lines menu → Settings → Block numbers → turn on "Block calls from unknown numbers." This works alongside Google's filter for double protection.
Method 3: Free Tools From Your Carrier
This is the step most people skip — and it's completely free. Every major carrier offers a spam blocking service. Call or text your carrier and ask them to enable it on your account. Here's exactly what each carrier offers:
📱 Verizon
Call Filter
Text "FILTER" to 4673 or go to the My Verizon app → Account → Add-ons → Call Filter. Automatically identifies and blocks likely spam.
FREE
📱 AT&T
ActiveArmor
Download the AT&T ActiveArmor app or call AT&T at 1-800-288-2020 and ask them to enable fraud blocking on your line.
FREE
📱 T-Mobile
Scam Shield
Text "PROTECT" to 7726 or open the T-Mobile app → More → Scam Shield. Blocks known scam numbers and warns you about likely spam.
FREE
📱 Consumer Cellular
Spam Call Blocking
Call Consumer Cellular at 1-888-345-5509 and ask them to enable spam call blocking on your account. Popular with many seniors in our community.
FREE
Method 4: The National Do Not Call Registry
The National Do Not Call Registry is run by the Federal Trade Commission (FTC) and is completely free. Registering your number means legitimate telemarketers are legally required to stop calling you within 31 days. It won't stop illegal robocallers and scammers — they ignore the list — but it eliminates the legitimate solicitation calls.
1
Go to donotcall.gov
Type this address directly into your browser. The website is run by the U.S. government.
donotcall.gov
2
Click "Register Your Phone"
Enter your phone number and email address. You'll get a confirmation email — click the link inside it to complete registration.
3
Wait 31 days
Telemarketers have 31 days to remove you from their lists. Registration never expires — you only need to do this once.
💡 Already Registered?
You can verify your number is registered at donotcall.gov without re-registering. Registration is permanent and never expires — so if you registered years ago, you're still on the list.
Know These Robocall Scams — They Target Seniors Specifically
Blocking tools stop most robocalls. But some still get through — and the ones that do are the most dangerous. These are the scams I see most often affecting seniors in the Venice area:
🏛️
The "Social Security" Call
A robotic or live voice claims your Social Security number has been "suspended" due to suspicious activity and you must call back immediately or face arrest. This is 100% fake. The Social Security Administration never calls to threaten suspension or arrest.
Rule: Hang up. SSA contacts you by mail only.
📦
The "Amazon Package" Call
A call (often automated) claims there's a problem with your Amazon order or that a large purchase was made on your account. They ask you to "verify" your account by providing your login or payment information. Amazon does not make unsolicited calls about orders.
Rule: Hang up. Log into amazon.com directly if concerned.
🏦
The "Bank Fraud Alert" Call
Caller claims to be from your bank's fraud department and says your account has been compromised. They ask you to confirm your account number, PIN, or transfer money to a "safe" account. Your real bank will never ask you to transfer money or share your PIN by phone.
Rule: Hang up. Call the number on the back of your card.
💰
The "You've Won a Prize" Call
You've won a cruise, lottery, or sweepstakes — but you need to pay a small "processing fee" or "taxes" first using gift cards. No legitimate prize requires you to pay anything upfront. The gift card request is the universal sign of a scam.
Rule: Hang up. Legitimate prizes never require gift cards.
👨💻
The "Medicare/Insurance" Call
Caller claims to be from Medicare or your insurance company and says you need a new card or updated information — they just need to verify your Medicare number. Your Medicare number is as sensitive as your Social Security number. Never give it out over the phone.
Rule: Hang up. Medicare contacts you by mail only.
🚨 If You Think You've Been Scammed
Don't be embarrassed — these scams fool people of all ages and intelligence levels. If you gave out personal information or sent money, call your bank immediately (number on the back of your card), then report it to the FTC at reportfraud.ftc.gov. Acting quickly can sometimes reverse wire transfers or stop further damage.
What About Robocall Blocking Apps?
You've probably seen ads for apps like Nomorobo, Hiya, or RoboKiller. They work — but honestly, for most seniors the free built-in tools above do 90% of what these paid apps do. I rarely recommend spending money on a robocall app when the carrier tools and built-in phone settings are already excellent.
The one exception: if you've done everything above and are still getting flooded with calls, Nomorobo is the most reputable paid option at around $1.99/month. It has a strong track record and is legitimate — unlike some "call blocking" apps that are themselves scams.
🛡️
Do These 3 Things Today and You're 90% Protected
Step 1: Enable Silence Unknown Callers (iPhone) or Filter Spam Calls (Android) — takes 60 seconds.
Step 2: Contact your carrier and ask them to enable their free spam blocking service.
Step 3: Register at donotcall.gov if you haven't already.
You'll notice the difference within days. And remember — the calls that do get through are the most dangerous ones. Hang up on any call that creates urgency, asks for personal information, or requests gift cards. No legitimate organization does any of those things.

Frequently Asked Questions
Common questions about stopping robocalls on iPhone and Android — answered from real experience helping seniors in Venice, Florida.
Q How do I stop robocalls on my iPhone?
The fastest way to stop robocalls on iPhone is to enable Silence Unknown Callers. Go to Settings → Phone → Silence Unknown Callers → toggle ON. This automatically silences calls from numbers not in your contacts and sends them to voicemail. You can still see missed calls and retrieve voicemails. For additional protection, contact your carrier and ask them to enable their free spam-blocking service — AT&T has Call Protect, Verizon has Call Filter, and T-Mobile has Scam Shield, all available at no charge.
Q How do I stop robocalls on Android?
On Android, open the Phone app → tap the three dots (⋮) in the top right → Settings → Caller ID & Spam → turn on Filter spam calls. This uses Google's spam database to automatically block known robocallers. For Samsung phones specifically, go to Phone app → ⋮ → Settings → Block numbers → enable Block unknown callers. Also register your number at donotcall.gov — it won't stop all robocalls but does reduce legitimate telemarketing calls significantly.
Q What is the best way to stop robocalls for seniors?
For seniors, the most effective combination is: (1) Enable your phone's built-in spam filter — free and requires no app. (2) Register at donotcall.gov — reduces legitimate telemarketing. (3) Enable your carrier's free blocking service — AT&T Call Protect, Verizon Call Filter, or T-Mobile Scam Shield. (4) Never engage with robocalls — don't press 1 to be removed from a list, as this confirms your number is active and often results in more calls. These four steps together eliminate the majority of robocalls without spending anything.
Q Does the Do Not Call Registry actually stop robocalls?
The Do Not Call Registry reduces legitimate telemarketing calls but does not stop most robocalls. Legitimate businesses respect the registry — charities, political organizations, and survey companies are exempt. But scammers and illegal robocallers ignore it entirely. Registering at donotcall.gov is still worth doing because it eliminates one category of unwanted calls, but it should be combined with your phone's built-in spam filter and your carrier's blocking service for meaningful protection.
Q Why am I getting so many robocalls on my cell phone?
Cell phone numbers end up on robocall lists through several channels: data breaches, online forms, sweepstakes entries, public records, and purchased marketing lists. Once your number is on one list it gets sold to others, which is why robocalls tend to increase over time. The good news is that your phone already has tools to fight back — your carrier's spam blocking service and your phone's built-in filter are both free and significantly reduce the volume. Seniors are targeted more heavily than average because scammers specifically target older adults.
Q Is there a free app to stop robocalls?
Before downloading any app, check what you already have for free. Your phone's built-in spam filter (Silence Unknown Callers on iPhone, Filter Spam Calls on Android) costs nothing and works well. Your carrier's blocking service is also free — AT&T Call Protect, Verizon Call Filter, and T-Mobile Scam Shield all provide meaningful protection at no charge. If you've used both and still want more, Hiya and YouMail both offer free tiers with additional robocall blocking. Avoid apps that charge monthly fees — the free options are usually sufficient.
