Just last week, 8,251 people got Nomorobo protection!


I was a happy subscriber, but was very annoyed when I started missing calls from friends - they called, I heard 1 ring, and they got disconnected as I picked up. I did not realize that this was happening because of NOMOROBO, the the ISP techs (Time Warner RR) were here twice and it took them a few weeks to realize that it was the doing of NOMOROBO, I lost many calls, including bi\usiness calls during those at least 4 weeks, until I disconnected from your service. You should explain that this can happen, or better - fix this VERY annoying and serious problem with your otherwise welcome service.I might join and recommend you if you do that.

My wife and I are finally getting control of our phone back. We love the peace and quiet that NOMOROBO has achieved for us. Thank You a hundred times.

Great! I love it!

Nomorobo has made my home a much nicer place to be. I thank you for eliminating most of the numerous pesky calls that interrupted my day and made me paranoid to answer my phone. Your service indeed does what it claims. Thank you.

I love this service!! It works about 90% of the time so really good! I am glad it finally works with Xfinity.

I signed up quite a while ago and it works great

Love it! Absolutely love it!! Thank you for creating it. I have recommended it to family and friends and they have thanked us.

Works great ! Now just find a way to include the political calls before 2016 and I will be in heaven!
