Verizon Call Filter affords users very little freedom to customize their call blocking experience. Unlike RoboKiller, users have to upgrade to get access to more precise spam blocking services.

Like most spam blockers, Verizon simply blocks calls from phone numbers on a block list—the problem is, scammers can just change numbers to get around that. RoboKiller, on the other hand, uses machine learning to detect scammers based on their unique audio fingerprints. Scammers may change their numbers, but they can’t change their voices.

Verizon offers SMS protection, but it can’t keep up with spammers like RoboKiller can. Our spam text blocking is 99% effective at identifying and shutting down text scams.

Some robocallers imitate local phone numbers so you’re more likely to answer them. Unlike Verizon, RoboKiller uses audio fingerprinting to combat neighbor spoofing. This capability makes RoboKiller more effective at identifying and stopping dangerous calls from similar-looking phone numbers.

RoboKiller doesn’t just block robocalls — we make it entertaining. Answer Bots answer your spam calls, mimicking a real person and wasting telemarketers’ time. You can even listen to the recordings. It’s a little poetic justice (and bonus entertainment) that Nomorobo just can’t offer.
