Enable your phone's hidden spam text defense

Your phone has a built-in spam text filter, but it may be disabled by default. This feature sorts messages from unknown senders into a separate folder, helping to protect you from scams. On iPhones, enable "Filter Unknown Senders" in Messages settings. Android devices automatically sort these messages into "Spam" or "Unknown" folders. Never respond to suspicious texts, even to opt out, as this confirms your number is active. Blocking numbers and reporting spam to your carrier can also help.
