Are you tired of being bombarded by annoying spam calls?

You’re not alone.

These unwanted calls can be a major headache, interrupting your day.

And that is not all, these calls potentially put you at risk of major scams.

Fortunately, there are several effective methods to block spam calls on your Android phone.

In this ultimate guide, we’ll explore what spam calls are, how spammers find you and detailed steps to block these unwanted calls using various features and services.

Before we get to the solution, let’s understand the problem in detail.

What is A Spam Call?

A spam call is an unwanted phone call that typically tries to sell you something, ask for your personal information or trick you into a scam.

These calls can come from telemarketers, automated systems (robocalls), or even fraudsters pretending to be from legitimate organizations.

Spam calls are not only annoying but can also be dangerous if you fall victim to a scam.

Spam calls can be divided into the following types:

• Telemarketing Calls: These are calls from companies trying to sell you products or services. While some may be doing real business, they often pry on personal information.
• Robocalls: These are automated calls that deliver pre-recorded messages. They can range from political campaign messages to fraud schemes.
• Scam Calls: These calls aim to deceive you into providing personal information or money. Common scams include pretending to be from a government agency, bank, or tech support.
• Phishing Calls: These are similar to scam calls but focus specifically on getting personal information including credit card numbers, Social Security numbers, or online account details.

How Spammers Find You?

The people behind those spam calls are professionals.

These spammers have several ways of finding your phone number.

Following are some of the commonly known methods.

These companies collect and sell your personal information, including your phone number, to marketers and spammers.

They gather data from various sources like online purchases, subscriptions, and public records.

When you fill out forms online, your phone number can be collected and shared with third parties.

It is advised that you should always check the privacy policies and opt out of sharing your information when possible.

If your number is listed publicly, such as in online directories or social media profiles, spammers can easily find it.

So, be cautious about where you share your phone number online.

Spammers use automated systems to dial random phone numbers, hoping to reach potential victims.

This is also known as “war dialling” and can flood users with unwanted calls.
