Receiving calls and messages from unknown numbers can be both inconvenient and potentially risky. Fortunately, there are several strategies you can employ to manage these communications effectively.
What Are Unknown Numbers?
An "unknown number" typically refers to a call or message from a number that doesn't display its caller ID information. This can include private, restricted, or unlisted numbers. While some legitimate calls may come from such numbers, they are often used by telemarketers and scammers to conceal their identity.
