Top Free Solutions to Block Sales Calls for Everyday Users in the United States

Unwanted sales calls are a pervasive nuisance for many Americans. Fortunately, there are effective and free solutions available to help you regain control over your phone.

What Are the Most Effective Free Methods to Block Sales Calls?

1. Utilize Built-in Smartphone Features

Both Android and iOS devices offer native features to combat spam calls:

  • Android: Many Android phones, especially Google Pixel and Samsung Galaxy models, come equipped with built-in spam protection. For instance, the Google Phone app allows users to filter spam calls by enabling "See caller & spam ID" and "Filter spam calls" in the settings. (whocalledus.net)

  • iOS: iPhone users can activate the "Silence Unknown Callers" feature, which automatically silences calls from numbers not in your contacts. Additionally, SMS messages are filtered into categories like "Transactions," "Promotions," and "Junk." (deadzones.com)
