In an ongoing effort to combat illegal robocalls and scam texts, the Federal Communications Commission (FCC) has released a new series of step-by-step guides designed to help consumers activate built-in blocking and filtering tools on their phones.

The newly published resources, available at fcc.gov/blockit, provide tailored instructions depending on a user’s specific device and mobile carrier.

To maximize protection against unwanted communications, the FCC recommends that consumers enable both their phone’s native features and the specific services offered by their provider. The guides cover major mobile operating systems—including Android and iPhone—as well as major carriers like AT&T, T-Mobile, and Verizon.

The initiative aims to give everyday users simple tools to screen unknown callers, filter spam texts, and regain control over their communication channels. Consumers looking to learn more about broader FCC efforts to stop illegal robocalls can visit fcc.gov/robocalls.
