Spam calls are a persistent nuisance, often leading to scams and unwanted interruptions. Fortunately, there are several methods to identify and block these calls, enhancing your privacy and peace of mind.
What Are Spam Calls?
Spam calls are unsolicited phone calls intended to promote products, services, or fraudulent schemes. They can range from robocalls delivering pre-recorded messages to live callers attempting to deceive you into sharing personal information. Recognizing these calls is the first step in protecting yourself.
