Spam calls are a persistent nuisance, often leading to scams and unwanted interruptions. Fortunately, there are several strategies you can employ to identify and block these calls on your mobile phone.
What Are Spam Calls?
Spam calls are unsolicited communications, typically from automated systems or individuals, aiming to promote products, services, or fraudulent schemes. These calls can range from robocalls delivering pre-recorded messages to scams impersonating legitimate organizations to steal personal information.

Built-in Features to Identify Spam Calls
Most smartphones come equipped with features to help users identify and block spam calls:

Be Cautious with Unknown Numbers: If you receive a call from an unfamiliar number, let it go to voicemail. Legitimate callers will leave a message.

Identifying and blocking spam calls requires a combination of utilizing built-in smartphone features, third-party applications, and carrier services. By staying informed and proactive, you can significantly reduce the number of unwanted calls you receive.
