Like an uninvited guest knocking without a word, silent calls from unknown numbers can spark unnecessary worry. These repeated attempts without voicemails often signal market research or survey efforts, not threats, but it's smart to stay cautious. Block the number if it persists, and use call screening apps to filter unknowns. Never share personal info over unsolicited calls—verify any claims directly with official sources. If it feels off, report to authorities like the Do Not Call Registry for peace of mind.
