How to Block Telemarketing Calls on Your Mobile Phone

Telemarketing calls can be a significant nuisance, disrupting your day and compromising your privacy. Fortunately, there are effective strategies and applications available to help you block these unwanted calls.

Why Are Telemarketing Calls a Problem?

Telemarketing calls are unsolicited communications from businesses aiming to promote products or services. While some are legitimate, many are intrusive and can lead to scams or privacy breaches. In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person per month. (antivirus.com)
