Scam calls often impersonate banks, delivery services, government agencies, or “tech support” to pressure you into paying money or sharing personal information.

Common scam call patterns

  • Urgency: “act now or your account will be closed.”
  • Authority: “this is the IRS / your bank / your phone provider.”
  • Spoofing: the caller ID looks local or looks like a real business.
  • Callback bait: missed call from an unfamiliar number to trigger a call back.

What you can do today

  1. Never share OTP codes, passwords, or card details on a call you didn’t initiate.
  2. Use whitelisting so real contacts get through without you turning protection off.
  3. Block repeat numbers immediately.
  4. Watch for spoofing (especially neighbor spoofing).
