Fantastic ! We have a 98% reduction in calls. No more unwanted messages !

The best service ever!! One rings means a robo call blocked. It makes me smile. Wish I could get the same service on my cell phone.

I love it however, a lot of robo calls still come thru. I am retired so home most of the time and i see on my TV before answering who is calling and i would say about 5 out of 7 get thru each day.I wish i knew how to get rid of the other 5.However, the ones you catch are great.

It seems to be working fine.I'm getting just a single ring now and I assume that's a call you've intercepted? Also, are you intercepting calls from WITHIN my state? (California)

Fantastic! My phone has numerous single rings daily as Nomorobo kills them. Suggestion: During the next election cycle can we block the surveys, get out the vote and money requests?
