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

I love NOMOROBO! I tell all my friends and family about it. I would like to see the option to block charities as well. I get calls several times a day from different cancer societies asking for donations.

Great service! Now I do not have to listen to Rachel of Credit Card Services!

It's great

It works! It's stopping about 8 calls a day. We love it.

Very effective. It brings me a small joy every time I hear the phone ring just once. I know Nomorobo just blocked another one! Thanks for a great service.

Nomorobo is a great service, that works. We had disconnected our internet phone because of robo calls. Our internet phone is now connected 24/7 and only rarely do we even get a one (1) ring call, let alone a call that makes it through. At this point no downsides. Whatever I say will not be your decider. Just try it and be amazed.

I love hearing the choked, abortive ring of a robo call being killed mid-ring! Die robo-call! Die! Can't wait to get this on my cell!
