The tools you need to live spam-free

Here are some of RoboKiller’s unique features (that you can’t get with Nomorobo):

Customizable call blocking

T-Mobile Scam Shield has limited functionality and provides little room for catering the call blocking experience to each user’s specific needs.

Audio fingerprinting

Like most spam blockers, T-Mobile 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.

Smarter spam text blocking

T-Mobile 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.

Protection against neighbor spoofing and caller ID spoofing

Some robocallers imitate local phone numbers so you’re more likely to answer them. Unlike T-Mobile, RoboKiller knows how to identify and stop these sneaky spam calls before they reach you.

Answer Bots
arrow down

RoboKiller doesn’t just block robocalls—we make it fun. Answer Bots intercept incoming spam calls and mimic a real person to waste telemarketers’ time. You can even listen to the recordings. It’s a little poetic justice (and bonus entertainment) that T-Mobile just can’t offer.

Silence from spammers. Praise from the press.
