Works great

I installed NomoRobo to keep unwanted calls from coming through. What I did was change my cell number with my wireless cellular provider and only provided it to drs or businesses I work with. Anyone else will get a different number by TextNow or GV. I’ve had NomoRobo for 2 weeks so far and I can say it works great for me. Any number from a dr whose in my contact list comes through. The rest NomoRobo blocks,silences and screens texts too. Thank you NomoRobo! I highly recommend this app because it works! It also allows you to accept calls if it’s screened. You can also put the number on your allowed or blocked list on the app and how you want that number handled by giving you 3 options.

Great app, needs multi esim support.

I hardly ever review apps but felt compelled to write one for Nomorobo. It works, I really love the call screening feature for non-spam numbers it has where the virtual agent will let me know who is calling and place the caller on hold until I accept / reject call. I was a bit skeptical at first about the call forwarding setup but after trying it for a couple of weeks I cannot recommend it enough. No robó calls have been allowed through and no important non-spam numbers have been blocked due to the call screening feature!

The only app suggestion I have as a multi-esim user is I would love the app to support its features on more than one line. As a Canadian ex pat I have both a Canadian and US number and cannot take full advantage of this on both lines. This is the only reason I did not give the app a perfect score.

For single-line users this app should work like a charm.

Thanks for your review!! The feedback is greatly appreciated. Glad to hear Nomorobo Max call screening has been working well.

Regarding multi-esims, we are actively investigating ways to support this. We plan to add Canadian carriers shortly, and would love to invite you to test it out. If you're interested, please reach out to us at

Max is my new best friend!

Nomorobo Max is completely magical! I no longer get stewpid calls all day long. Max grabs then usually before my call phone even rings at all. I then get a brief audio and transcription of the callers feeble attempt to waste my time and scam me, so that I know that call was bogus. When a legit call gets blocked and they leave enough identifying info to let me know as much, I can often pick up the call while they’re still waiting or easily tap on their number and call them right back (and then quickly add them to my contacts). Max is well worth the subscription cost to avoid spam calls and texts!

Excellent! We are glad you are loving it! Bye-bye, scammers and time wasters!
