Just last week, 8,272 people got Nomorobo protection!

Every time the phone rings once and then goes silent, I say thank you!

It's great! Let the phone ring once. If it rings again, it's real. In not, we say, "Gee, Thanks, NOMOMOBO!

Nomorobo is the best! And it was suggested to me by my telephone service supplier! That company, Optimum/Cablevision, allows 30 numbers to be blocked at their website.. I asked for more and the service person advised me to sign up for Nomorobo. Terrific! And I can see, on my phones, what numbers or "non-numbers" have been blocked.

Love it, it stops about 10 calls a day. Saved us from just cancelling our home phone which is still considered.
— Frank P, Nov 29th, 11:36am
I have already recommended Nomorobo to all of my friends. I love it! We get so many calls that are now handled with just one ring! I wish my mother-in-law had signed up...she was just scammed out if more than $2000 by a robo caller from Canada.
