How to Block SMS Spam on iOS 11

iOS 11 now allows you to send incoming SMS messages through third-party filters, just like spam processing in email programs. The good ones are filtered into your main Messages view, while the bad ones land in a separate tab.We will try to shed some light on how to block SMS Spam on iOS 11.

How to block SMS spam on iOS 11
These steps will help you block SMS Spam on iOS 11:

  1. Download an SMS spam blocking app (we’ve mentioned our favourites below).
  2. Go to Settings > Messages.
  3. Under Message Filtering, tap Unknown & Spam.
  4. Under SMS Filtering, select the spam blocking app you want to use.

SMS spam blocking apps on iOS 11
There are several SMS spam blocking apps on the App Store and we used many of them since the launch of iOS 11 to figure out which ones work the best. The Following are our favourites app to block SMS Spam on iOS 11 :


VeroSMS - SMS Spam on iOS 11

VeroSMS is a free app that lets you block spam messages via targeted keywords. An in-app purchase worth Rs. 80 lets you block texts based on crowdsourced keywords. If you don’t want to pay much, this app does a great job blocking spam messages as long you have the patience to manually enter keywords to block. These keywords can also be the name of a sender such as HLACHF or DUNKIN and the app will put them in the junk folder. VeroSMS is competent at getting the job done, but the problem is that you have to do most of the work.

Hiya Caller ID and Block

Hiya Caller ID and Block - SMS Spam on iOS 11

Best call blocker and caller ID lookup for iOS10. Hiya identifies the important calls you want to take and blocks numbers that you want to avoid.

SMS Shield

SMS Shield

SMS Shield is a subscription-based app (Rs. 300 per year) that allows you to block spam messages both manually and using its own machine learning algorithms. SMS Shield worked quite well for us overall and blocked more spam texts than other apps. It supports blocking by receivers as well, so you can block all texts originating from shortcodes such as “VK-HLACHF” by adding *-HLACHF as a blocked number under the Custom Block List feature. There’s no easy way to create a whitelist, but you can report individual messages as not spam by pasting the text in the app.

SMS Checker

SMS Checker
SMS Checker is a free app if you just want to block texts manually via keywords. There’s an in-app purchase (Rs. 500) to enable online filters for automatic blocking. If a subscription based blocking app is not for you, then you can pay a one-time in-app purchase and get SMS Checker. The app makes it very easy to create a whitelist and a blacklist, with multiple toggles for custom keywords in the message or in the name of the sender. Its automatic spam message blocking isn’t as good as that of SMS Shield, but that could change based on how many people use the app, and how often its filters get updated.
