Really works!

I’m loving Nomorobo Max! I haven’t had an unwanted spam call in weeks. I love the call screening. I now know who is calling, even from unknown numbers. Just today Nomorobo blocked three spam calls! My phone didn’t ring once. Love it! Keep up the good work

Performs as advertised

I’m still in the 14-day trial period, but already I notice how “clean” my emails and text messages have become. I’m sold!

Pls update your supported carrier list!

I’m sad! 😔 I downloaded to try and had planned to pay for your app subscription …but you do not support the TFW (Straight Talk) network yet. Will check back at a later time to see if you’ve expanded your availability for other networks.

Developer Response ,

Thanks for leaving a review! Nomorobo Max is currently available on AT&T, T-Mobile, and Verizon. We're working to add additional phone carriers, and will update accordingly when we are able to. For now, I'd recommend checking out the Nomorobo Basic mobile app, which can be used on ALL phone carriers.
