The number of spam from robocalls is increasing every year in the USA. And according to the latest statistics, Americans received more than 60 billion unwanted calls in 2019 alone. So, expect more than that in 2023, and stopping telemarketing on cell phones is not that hard and complicated if you follow the right tips and tricks. Yet, getting spam calls from telemarketers and scammers all the time is frustrating.

That becomes complicated, especially when you see another new number that calls, you block it, and another number pops up the next day.

Now, here is how you can stop the annoying calls on your mobile phone. Try the first options and that will eliminate the majority of these unwanted calls.

Stopping robocalls on mobile numbers

Many people think that Robocalls are out of control, and that’s somehow true. But there is always a solution to fix a problem. And the first recommended way is The National Do Not Call Registry website.

That can help to reduce the number of Robocalls you receive on your mobile number. However, it’s not true that they’ll remove all the spam calls completely. In fact, users still get robocalls from organizations, charities, political groups, and campaigns, and so on. So, it’s not the end of these automated phone calls if a user just adds his number to this database. But, it’s worth it in terms of service.

To successfully report a spammer number, visit the official website And then, fill in the form by describing exactly what the robocall was about, and make sure you add the category of that call.

Try robocall blocker apps

Actually, there are many robocall blocker apps for iOS and Android devices. So, try one from the following list. But first, it’s your own responsibility to verify the review about each app and only install it after checking other details like their website. There are millions of apps for mobile devices and things can keep going well for a time. And then, the app may be abandoned and even be out of date which will slow down your smartphone and make things worse.

For that reason, verify that the Robocall blocker app you want to install has thousands of reviews. In addition, make sure the tool has lots of installations. Moreover, you need to add the tool after checking that it has at least a few screenshots. That allows you to see how it works and what it offers as features, tools, etc…Some of these tools come with phone number verifications, and that can tell you for sure, who is the person behind that unknown caller.

This is a good application that allows you to automatically block telemarketers on any cell phone number. In addition to that feature, there is a huge directory index of spam numbers that others reported and added comments about. So, it’s also another way to identify the caller and see who it’s in reality and even see the transcript of that harassing Robocall you got recently.


Nomorobo for cell phones can be installed on Android and also iOS. It’s another solution to limit the number of robocalls.

How to prevent spam calls on mobile

It’s not the time to find how telemarketers got your cell number and now they automate spam calls. If they have your details, they’ll keep using that number over and over again. Even if you block them, spammers will use another number or just sell databases of millions of contact details to other companies.

So, to prevent robocalls on a cell phone, it’s always crucial to be the person who protects his details from being scraped or found online. Make sure you keep your number private, never add it in comments or posts on social media sites like Facebook or others. Search engines like Google can access this information and personal details. Then, when someone wants to find your cell number, he can find it online and the unsolicited calls start from there.

Bottom line

Reporting robocalls on mobile numbers is easier with the latest apps and innovations. But once a telemarketing company gets your number, it will sell it to another organization and the list will never end up. That’s why protecting your phone number from being listed online is the first step and the most important prevention against getting robocalls from spammers.
