Unknown numbers are how most modern scams start. Burner Phone Checker tells you in seconds whether the call or text is a known scam pattern, a spoofed caller-ID, a robocaller, or a number freshly reported by other users this week. Paste the number or upload an SMS screenshot into ScamGuard — you'll get a clear verdict, a plain-language reason, and the next step. Works on phone, desktop and WhatsApp.
