Just last week, 8,280 people got Nomorobo protection!

We usually have dinner around 7pm and it seems like that is when robocalls start. It is great to hear the phone ring only once and not have to interrupt dinner to answer the phone. Nomobo made dinner enjoyable!

It's great, however, we still get one ring before robocall rejects the unwanted call. It cuts down on the annoyance but I sure wish it would eliminate that one ring.

We LOVE Nomorobo. We've reported around 50 numbers ourselves and say thanks to Nomorobo every day when time-wasting robo/slamming/ con calls are intercepted after one ring. We've told everyone we know about the service. It really works. Thank you!

What can I say? This is the best deal in a long time. It really works and am so grateful that I hear one ring, and no more. If anyone doubts this program, please get your friends, neighbors to sign up. Thank you so much for this program. I have gotten my friends to sign up. They love it

The greatest thing since Private telephone numbers and no more Party Lines. We chuckle every time a call is blocked, knowing that we didn't need to get up from what we were was doing. I keep an updated record of all unwanted calls my Call Blocking Phone and of those my friends at NOMOROBO, block for us. Interesting stuff, many thanks...

Thank you, thank you,thank you. This has been the best thing since cell phones. Having my phone only ring one time brings a smile to my face.
