Just last week, 8,259 people got Nomorobo protection!

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

What a blessing during the recent political campaign!!! It is also useful for senior related calls such as home security and "I just fell and can't get up" scare tactics. I recommend to everyone who complains about robocalls.

You're wonderful.

Trying to stop or at least limit Robocalls almost became a part time job for me. I would diligently try to use their "press 5 to be removed from our list" [yeah, THAT works!], & even more diligently report the numbers/caller ID in complaints to the Do Not Call Registry. Pretty much to no avail & a losing battle. Then I read about Nomorobo. Gave it a try & OMG, what a difference! An IMMEDIATE difference! A real Godsend --- The peace is wonderful. One little ring & then nothing. Thank you so much!!

I love this service. It blocks so many of these robo callers. I laugh at the tricks these callers use to disguise themselves. Nomorobo helps me a lot.

Thank you! I had doubts about nomorobo - I was so wrong! I love it! You all should win some sort of peace prize!

Before Nomorobo we would get some 20-30 auto dialer calls a day. We had even gone so far to buy a phone that announces the caller's ID, so we wouldn't answer the 800 calls. But then the masked local calls started coming too. I seriously considered getting rid of our home phone. I am so happy with Nomorobo. This service has seriously saved me and my husband countless and daily aggravation.

I find it aborts calls after 4 rings but doesn't block them. I still get many unwanted calls.
