## What is Spam Text Blocker by Nomorobo?

Take back your Messages inbox with Spam Text Blocker by Nomorobo.

Nomorobo’s award-winning technology is now built for text messages and helps filter spam and scam SMS and MMS from unknown senders, so you spend less time dealing with junk and risky links.

Stay focused on real conversations while suspected spam gets filtered out before it distracts you.

KEY FEATURES
• Filter spam and scam texts from unknown senders
• Reduce distractions from promotional and fraudulent messages
• Simple setup in a few steps
• Built with Nomorobo’s 10+ years experience fighting unwanted communications

HOW IT WORKS
Spam Text Blocker runs as an iOS Message Filter.

• The initial filtering happens on your device.
• For some messages, iOS sends a non-identifying request through Apple’s message filtering services to help determine whether a message looks like spam.
• We never receive info that directly identifies you (like your phone number, Apple ID, or contacts).
• The result is used only to classify messages as junk or allowed.

PRIVACY
We’re built for spam protection, not data collection.

Spam Text Blocker filters on-device and may use Apple’s message filtering services to send a non-identifying request to Nomorobo’s servers for classification. We do not receive your phone number, contacts, or any other information that directly identifies you. Data is used only to provide and improve spam filtering.

### 2/5 — Sending you spam calls

*2026-07-13*

I can’t seem to send you spam call numbers.

### 1/5 — Rubbish

*2026-07-03*

Gets the basics wrong. Don’t waste your money.

### 1/5 — Waste of money

*2026-02-27*

1. No way to exclude filtering based on known contacts. 2. Fails to block certain messages using custom keywords that it is configured to block, and that the built-in test says would be blocked. 3. Fails to block a majority of political spam out of the box. The best I can say is ... it works sometimes? I definitely have it set up correctly.

**Developer response:** Dear JN,

Thank you for your feedback. 

1. We don't block any messages from your contacts (it's actually Apple that makes sure this never happens).
2. We'd love to help you with this, so do you mind sharing more information with us via support@nomorobo.com? Mind you, we can't block iMessage messages (Apple prevents that) and we can't block any message that was sent from your existing contact.
3. We're working hard on making sure that none of the bad messages come through. Mind sharing with us some that came through? 

Thank you,
Nomorobo Support
