(408) 851-5020 is a Chinese Robocall

Has reduced my bothersome calls by 90% Thanks Nomorobo!

Doesn't block every nescience calls but its still great. Thanks

This is the best thing that has ever come out, no more annoying robocalls since signing up for this. I tell everyone about this awesome service and encourage everyone to sign up for it. Just waiting for the ability to set this up on my mobile device.

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.

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...

It feels like we get one call per day with one ring. That indicates to me that Nomorobo has picked it up and blocked it. What a nice relief to have one more phone scammer blocked. Keep up the excellent work.

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.

I love the concept but it does not work 100% - one initially the program was designed to block the calls from even ringing. Now when I get the calls - my phone rings one time. That one time is annoying and I never know when the phone rings is it a blocked call or a real call starting to come in. I have to pause to see which one. I still get the scammers come in, since they have also outsmarted the system by changing their numbers to local or hijacked phone numbers and ids. Overall I am glad to have such a system but it needs work.
