Blocking incoming calls can be a useful feature for various reasons, such as avoiding spam calls, telemarketing, or unwanted interruptions. It allows users to control who can reach them via phone calls, providing them with privacy and peace of mind.
Historically, call blocking was done manually by screening calls or using call-blocking devices. With the advancement of technology, smartphones and mobile networks now offer built-in features and apps that make it easy to block incoming calls from specific numbers or unknown callers.
