Best Spam Call Blocker for Android and iPhone

Put an End to Harassing Robocalls with Spam Blocker Mobile Apps

Are you utterly fed up with the avalanche of spam calls bombarding your smartphone daily? You‘re far from alone – illegal robocalls have exploded to an estimated 50 billion in the US annually according to the FCC. End the harassment once and for all with guidance on picking and optimizing call blocking apps.

Understanding the Depth of the Robocall Scourge

To grasp the sheer scope of mass automated calls, it helps to cover some key realities:

  • Robocalls utilize autodialing to blast millions of calls per hour from overseas call centers. The tech can fake legitimate numbers using number spoofing. This enables endless harassment.
  • The FTC receives over 500,000 complaints each month on violations from robocalling campaigns, typically involving financial frauds or data theft.
  • Estimates claim nearly 50% of all mobile calls now originate with illegal spam and telemarketing campaigns from fake numbers and names.

So why does fighting back against wrongdoers feel like an uphill battle? Consumer adversity comes from robocalling being an enormously profitable business with little risk. Setting up autodialing to millions is cheap, while weak laws let overseas scam centers operate unchecked.

However, you can gain peace of mind through mobile apps that block or filter these pesky unwanted calls. Now let‘s cover your defensive options…

Key Capabilities for Eliminating Spam Calls

To maximize blocking of illegal telemarketers and robocalls, an app should provide:

  • Blacklisting of known spam numbers
  • Caller ID lookups against database
  • Filtering calls to voicemail
  • Easy personal blocking
  • Reporting tools to train algorithms

Additionally, integration across all your devices ensures consistency in handling unwanted calls:

  • Mobile devices – iOS and Android
  • Landlines – VoIP and traditional
  • Small business phone systems

Select apps also offer improved call management capabilities through smart assistants that screen unknown callers with options to accept, deny, or flag for followup.

Next let‘s explore your top choices for putting up walls against telephone harassment.
