About Nomorobo Max
Try out Nomorobo Max and you won’t be bothered by *any* unwanted calls. None. Zip. Zilch.
Supported Phone Carriers: AT&T, T-Mobile, Verizon, Xfinity Mobile, Mint Mobile, and Spectrum Mobile.
Here’s how it works:
AUTOMATIC CALL SCREENING:
When an unknown caller rings your line, Nomorobo Max will ask the caller to state their name and the call’s purpose. You’ll listen to the brief message and either accept the call, reject it, or send it to voicemail. You can then choose to block that number or add it to your contacts. Nomorobo Max also cross-references the incoming number against its global database of millions of scam phone numbers and screens the caller’s dialogue for common scamming terms and language patterns.
SMS SCREENING:
For even greater phone protection, Nomorobo Max can detect spam texts as well. When SMS screening is enabled, Nomorobo Max can analyze text messages from unknown senders and check the number against a robocaller database, as well as URLs in the body of the message against a suspicious URL database.
With Nomorobo Max, you never have to trade your privacy for protection.
Your contacts stay safely on your phone. We don't push ads and we don't track your location. We just protect your phone from illegal and unwanted calls and texts.
