Verizon Block Anonymous Calls [cracked] -

Use *77 temporarily during high-spam seasons (e.g., election or tax season), then turn it off when you’re expecting legitimate private calls.

Turn it on for a few days. Check your voicemail regularly. If you see important missed calls from “No Caller ID” leaving voicemails, turn it off and rely on Verizon’s Call Filter or a third-party app like RoboKiller instead. verizon block anonymous calls
