Why we love it

  • CALLER ID REQUIRED: The V100K Call Blocker requires Caller ID service to be activated by your telephone provider. Without Caller ID, the device cannot identify incoming numbers for blocking or manual entry.
  • Powerful Blocking, Made Simple: Preloaded with 100,000 verified scam and nuisance numbers, the V100K starts protecting you right out of the box. And if a new or spoofed number gets through, the large “BLOCK NOW” button makes it easy to instantly block it - up to 10,000 additional numbers at your command.
  • Realistic & Reliable Protection: While no device can stop 100% of spam (scammers constantly change numbers), the V100K gives you the power to shut down repeat offenders quickly and effectively - offering more control than passive filters alone.
  • Hassle-Free Design: No power supply needed, no app, and no subscriptions. The V100K is easy to install, with a clear screen and loud button click for extra confidence. Designed with seniors in mind, it’s ready to use and simple to maintain. For even stronger protection, you can pair it with your phone provider’s spam filtering service.
