Symptoms
- Robocalls continue despite blocking individual numbers
- New spam numbers appear constantly, often similar to your own area code
- Automated messages play as soon as you answer
- Blocked numbers keep calling from slightly different numbers
Likely causes
- CommonScammers cycling through spoofed numbersBlocking one number does little when the next call comes from a different spoofed one.
- CommonCarrier-level spam filtering not enabledThis is usually more effective than blocking numbers one at a time.
- PossibleBuilt-in phone spam protection settings turned offBoth major mobile operating systems have settings to silence unknown callers.
What to do
- Turn on your carrier's network-level spam blocking or labeling service, often free, through their app or by dialing a short code.
- Enable 'Silence Unknown Callers' or equivalent on your phone so only known contacts ring through.
- Avoid answering or pressing any buttons on robocalls, since interacting confirms your number is active.
- Add persistent numbers to your phone's block list, understanding it won't stop spoofed variants.
- Consider a dedicated call-blocking app with a large spam number database if built-in tools aren't enough.
- Register with the National Do Not Call Registry for legitimate telemarketers, and report illegal robocalls to the FTC.
When to call a pro
No professional help needed; if scam calls include threats or impersonate government agencies demanding payment, report them to the FTC rather than engaging.
