Just last week, 8,263 people got Nomorobo protection!

it has been a mindsaver........the phone may ring once and the call is caught!!! it has lessened the amount of calls dramatically!!! Thanks Nomorobo, you are the first line of defense against annoying robo calls!!

This has been a huge help to us. I have a question. We get quite a few calls where the phone rings once and no one is there. There is not a record of who called on Called ID. Could these be robo calls that did not get blocked in time? Is it a problem with Comcast?

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.

Working perfectly! The very small number of calls I now receive often just ring once. Many fewer junk calls than ever before. Thank you!
