SMS Filter cleans up junk or spam SMSs by using a curated list of spam keywords across different categories. You can add your own block list of keywords or phone numbers to filter spam. If any SMSs have to be always allowed you can add specific keywords to the whitelist as well (like OTP, verification code etc)

SMS Filter is private and never sends any of your SMSs over the network.

How to enable SMS Filter
1. Open Settings App
2. Tap on Messages
3. Tap Unknown and Spam
4. Enable SMS Filter

SMS Filter is free to try for 2 weeks. Only after 2 weeks you will be charged for the annual plan. If you don’t like the service SMS filter provides you can cancel the subscription anytime before 2 weeks and you wont be charged. That said we really hope you like what SMS Filter provides so that you can block unwanted spam and junk SMS on your iPhone easily.

Developer Response ,

Sigh, we are sad that the app is not working according to your expectations. If you get a lot of junk messages from the same sender and an important message like OTP comes in via the same sending, then iOS treats the new message as junk too. This is how it is handled by iOS (even if you have added specific keywords to the whitelist)

One option to solve this is to delete the thread first, and then new incoming messages will come in the right folder.
