FAQs
I've enabled and verified Nomorobo on my phone. What do I do now?
Continue to use your phone like normal. All you'll need to do is to wait for the second ring to answer the phone for incoming calls, as Nomorobo needs the first ring to detect robocallers. If you only hear one ring and then it stops, you know a robocaller was just blocked. If the phone continues ringing, you can answer it.
Will this block my doctor's office, prescription reminders, school closings, weather advisories, etc.?
No. The only numbers that are blocked are reported, illegal robocallers.
A robocaller still called me. What happened?
Occasionally, a robocaller or telemarketer will slip through, as Nomorobo must constantly adapts to their changes in tactics. If you do get a robocall, please report it here.

No. At this time, Nomorobo isn’t compatible with Xfinity Voice Unlimited Saver or Local With More call plans.
What about political and charity calls?
Nomorobo does block political robocalls. You can enable or disable this feature by clicking Edit next to your number when signed into your account on the Nomorobo website. Nomorobo doesn’t block charity calls.
