Just last week, 8,252 people got Nomorobo protection!

Has worked great for me. A few calls slip thru occasionally. And some are with my name, number

It has reduced unwanted calls significantly. I have already told friends about it. Now if only it could block calls with caller IDs of Blocked or Anonymous that would be the icing on the cake. We never accept those calls.

My husband has Alzheimer's & the constant ringing of the phone was driving him & Me crazy, he could not understand why I would not answer it. I feel like someone was looking down on me when I found your service - my phone has been quiet since the day I started & if it is a rare important call it comes right to my iPhone in readable text

Fantastic service! We used to get dozens of calls a week. Very few now go through.Thank you!

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.

Great product. Thank you, but unfortunately more and more calls are getting through.

We signed up for Nomorobo on our 2 landlines as soon as it became available to us, which was a little over a year ago. We cannot thank you enough for making our home robocall-free. We absolutely love the service. Every once in a while, a robocall gets through, but that is rare. On 2 phone lines for more than a year I think maybe a few calls got through. We are totally satisfied with Nomorobo and I have recommended it to others. I am looking forward to the day when this service is available on cell phones. Thank you so much for being innovative enough to have developed this service.
