When you get a call from an unfamiliar number, it's best to stay cautious. Let the caller speak first, but don't share personal info or click on any links they mention. If they pressure you for money, claim you owe a debt, or say you've won a prize, hang up and verify independently. Consider blocking the number or reporting it to your carrier. A quick search of the number online can also reveal if others have flagged it as a scam. Stay alert and trust your instincts—if something feels off, it's probably best to end the call.
