Text spam na usually trying to get you to click, call, pay, or share. Block Guard now handles text spam through both rule-based filtering and link-safety checks inside di messaging workflow.

Step 1: Make Block Guard your default SMS app

Android only allows one default SMS app to fully send, receive, and filter SMS and MMS. Without wey role, Block Guard cannot run di full messaging and text-blocking stack.

Step 2: Turn on text blocking

  • Open Text Message Blocking.
  • Enable di master toggle.
  • Use di three tabs for blocked senders, blocked keywords, and blocked message log.

Step 3: Add sender and keyword rules

  • Add exact blocked senders for repeat offenders.
  • Add regex sender rules when spam rotates through one number pattern.
  • Add keywords or regex keyword rules for repeated bait like fake delivery notices, loan spam, or prize scams.
  • Whitelist trusted senders when a real conversation should bypass aggressive rules.

Step 4: Watch for dangerous links

  • Block Guard warns on known phishing domains.
  • It fit also warn on suspicious shortened links, payment lures, credential harvesting language, and urgent-action wording around a link.
  • If a warning appears, do not trust di message just because di sender looks familiar.
