Spam calls are one of those small annoyances that can quickly become a daily problem. A random number interrupts your work, a fake support agent claims there is an issue with your account, or an automated voice tries to convince you that you have won something you never entered.

The good news is that modern iPhones and Android phones already include several tools to reduce unwanted calls. You do not always need to install another app or pay for a service.
The most effective approach is usually a combination of built-in call filtering, carrier protection, smart call identification, and better habits that prevent scammers from knowing your number is active.
Why Do You Keep Getting Spam Calls?
Before blocking spam calls, it helps to understand why they keep reaching you.
Most spam calls happen because phone numbers are collected, leaked, shared through marketing lists, or generated automatically by software that tries thousands of possible numbers.
Sometimes your number ends up on a list after you sign up for a website, enter a giveaway, request information, download an app, or provide contact details to a business.
Scammers also use a technique called caller ID spoofing.
This allows them to make a call appear as if it is coming from a local number, a government office, a bank, or even a familiar area code. The number you see on your screen may not be the actual source of the call.
That is why simply blocking one number rarely solves the problem permanently. The goal is to reduce unwanted calls before they reach you.
Start With Built-In Spam Protection
The easiest place to begin is your phone’s own settings.
Both iPhone and Android have built-in tools that can identify suspicious calls, silence unknown callers, and help you avoid answering obvious spam.
These features are not perfect, but they can remove a large percentage of annoying calls without requiring extra apps.
How to Block Spam Calls on iPhone
Apple includes several options that can help reduce unwanted calls.
Turn On Silence Unknown Callers
One of the most useful iPhone features is Silence Unknown Callers.
When enabled, calls from numbers that are not saved in your contacts, recent outgoing calls, or Siri suggestions are sent directly to voicemail instead of making your phone ring.
To enable it:
Settings > Apps > Phone > Silence Unknown Callers
This works well if most important calls come from people already saved in your contacts.
The downside is that it can also silence legitimate calls from places such as a doctor’s office, delivery company, recruiter, or business you have not contacted before.
If you regularly receive calls from unknown but important numbers, this setting may feel too aggressive.
Use Live Voicemail Screening
Newer versions of iOS include Live Voicemail, which shows a real-time transcription of a voicemail message while someone is leaving it.
This gives you a chance to see why someone is calling without immediately answering.
If it is a legitimate call, you can choose to pick up.
If it looks like spam, you can ignore it.
Block Individual Numbers
If the same number repeatedly calls you, blocking it is still useful.
Open the Phone app:
Recents > Tap the information button beside the number > Block Caller
Keep in mind that scammers often change numbers frequently, so blocking individual numbers works best for repeated calls from the same source.
How to Block Spam Calls on Android
Android phones vary slightly depending on the manufacturer, but most recent devices include spam protection features through the Phone app.
Turn On Caller ID and Spam Protection
On many Android phones:
Phone app > Settings > Caller ID & Spam
Enable options such as:
- See caller and spam ID
- Filter spam calls
- Block suspected spam calls
Google’s Phone app can automatically identify suspected spam and warn you before answering.
This is especially useful because many spam calls are recognized based on patterns from Google’s call-identification system.
Use Call Screen on Supported Phones
Some Google Pixel phones include Call Screen, which allows Google Assistant to ask the caller why they are calling before you answer.
This is one of the more effective tools because many automated systems and scammers do not respond well to screening.
Instead of you wasting time with a suspicious caller, the phone handles the first interaction.
Block Specific Numbers
Like iPhone, Android allows you to block individual callers.
Open your recent calls, select the number, and choose the block option.
This will not stop every spam call, but it is useful for repeated unwanted numbers.
Use Your Carrier’s Spam Protection
Your mobile carrier may already offer spam filtering as part of your plan.
Major carriers in the US provide tools that can identify suspicious calls before they reach your phone.
These systems often work alongside your smartphone’s own protection.
Carrier-level filtering can be useful because it happens before the call reaches your device.
That means your phone may never need to ring for calls already identified as suspicious.
Check your carrier’s app or website to see whether spam protection is available and whether it is included with your plan.
Should You Install a Spam Call Blocking App?
Third-party apps can help, especially if you receive a large number of unwanted calls.
Popular call-identification apps maintain databases of reported spam numbers and can warn you before you answer.
They can be useful, but they are not magic.
A new scam number may not appear in a database yet. Some apps also require access to your contacts or call information, so it is worth checking privacy settings before installing anything.
I would start with your phone’s built-in protection first.
If spam calls continue to be a serious problem, then consider adding a reputable call-filtering app.
Do Not Answer Unknown Calls Automatically
This sounds simple, but it makes a difference.
Many spam systems track whether a number answers.
If you repeatedly answer unknown calls, automated systems may consider your number active and increase future attempts.
Instead:
- Let unknown calls go to voicemail
- Check whether the caller leaves a message
- Search suspicious numbers before calling back
- Avoid confirming personal information to unknown callers
A legitimate company usually has another way to contact you or will leave identifying information.
Never Press Buttons During Suspicious Calls
Many automated spam calls ask you to press a number to speak with an operator or remove yourself from a list.
Be careful with this.
Sometimes pressing buttons simply confirms that a real person answered the phone.
If a call feels suspicious, the safest option is usually to hang up.
Do not provide:
- Passwords
- Verification codes
- Banking information
- Social Security numbers
- Account login details
No legitimate company should ask for sensitive information through an unexpected call.
Register Your Number With the National Do Not Call Registry
If you are in the United States, adding your number to the National Do Not Call Registry can reduce legitimate telemarketing calls.
It will not stop scammers completely because criminals do not follow these rules, but it can reduce calls from companies following marketing regulations.
You can register through the official Do Not Call website.
What About Robocalls?
Robocalls are automated calls made using software instead of a human caller.
Some are legitimate, such as appointment reminders or notifications you requested.
Others are scams.
The best defense is layered protection:
- Carrier spam filtering
- Phone settings
- Call identification tools
- Not answering unknown numbers
- Blocking repeated callers
No single setting can guarantee that every unwanted call disappears.
How to Stop Spam Text Messages Too
Spam is not limited to phone calls.
Text messages are another common way scammers reach people.
Avoid replying to suspicious texts, even if they ask you to reply with words like “STOP.”
For legitimate marketing messages, STOP usually works. For random scam messages, replying may confirm that your number is active.
Instead:
- Block the sender
- Report spam through your messaging app
- Avoid clicking unknown links
- Do not provide personal information
Keep Your Phone Easier to Handle With the Right Accessories
Blocking spam calls is mainly about software and settings, but the way you use your phone every day also matters.
A comfortable grip can make it easier to manage calls, messages, navigation, and other tasks without worrying about dropping your device. A reliable charging setup also helps when you rely on your phone throughout the day.
These accessories will not block spam calls directly, but they can improve your everyday phone experience.
1
PopSockets Adhesive Phone Grip: Useful for Everyday Phone Control
The PopSockets Adhesive Phone Grip is a simple accessory designed to make holding a smartphone more comfortable.
It attaches to the back of compatible phones or cases and gives you a small grip point that can reduce hand strain during extended use.
For people who spend a lot of time checking calls, messages, navigation, or social apps, a grip can make one-handed use easier. It can also work as a small kickstand when you want to watch videos without holding your phone.
The important thing to understand is that this does not filter calls or identify spam. It solves a different problem: making daily phone handling more comfortable.
At the supplied listing price of around $9.94, it is a relatively inexpensive add-on if you already spend several hours a day using your phone.
I would consider it useful for anyone who frequently uses a larger phone and wants a more secure hold.
It is not a spam solution, but it is the type of small accessory that can improve how you interact with your phone every day.
2
LISEN Retractable Car Charger: Keep Your Phone Ready While Traveling
The LISEN Retractable Car Charger is another practical phone accessory, especially if you spend a lot of time driving.
This retractable car charger is designed to provide charging options from a vehicle power outlet while keeping cables more organized than traditional loose charging cords.
The value here is convenience.
A phone that runs out of battery during travel can create problems when you rely on navigation, calls, messages, or emergency communication. Keeping a dedicated charger in your vehicle reduces the chance of reaching for a dead phone when you need it.
The supplied listing shows a price of around $16.99, making it a relatively affordable car accessory.
Like the PopSockets grip, it does not block spam calls. Your phone settings and carrier tools handle that job.
But keeping your phone charged and easy to use supports the bigger goal: making your phone reliable when you actually need it.
The Best Spam Call Setup in 2026
If I wanted to reduce spam calls as much as possible, I would combine several small protections.
My setup would look like this:
- Enable Silence Unknown Callers on iPhone or spam protection on Android
- Use carrier-level spam filtering
- Keep the phone software updated
- Avoid answering suspicious numbers
- Block repeat offenders
- Never share sensitive information during unexpected calls
- Use voicemail as a filter
The goal is not just blocking individual numbers.
The goal is making your phone smarter about deciding which calls deserve your attention.
Final Thoughts
Spam calls are unlikely to disappear completely, but you can reduce them significantly with the right combination of settings and habits.
Start with the tools already built into your iPhone or Android phone. Turn on spam identification, silence unknown callers when appropriate, use carrier protection, and avoid interacting with suspicious callers.
Most people do not need to install five different apps or buy expensive tools.
A few smart settings can remove a large amount of daily frustration.
And if you are improving your overall phone setup, small accessories like a comfortable grip or reliable car charger can make everyday use easier, even though they are separate from spam protection itself.
The best phone setup is not just about blocking unwanted calls. It is about making sure the important ones get through when they matter.
