How to permanently block all SMS on your Xiaomi phone: 5 proven methods

Spam, emails and messages from banks have flooded your Xiaomi? Want to completely disable SMS so that they do not distract from work or waste your device memory? In this article, you will find 5 working ways to block all incoming and outgoing messages on Redmi, POCO and other models running MIUI 14/15.

We’ll look at both standard system tools and third-party solutions, from simply disabling notifications to completely blocking SMS at the operator level. Importantly, some methods may affect other services (e.g. two-factor authentication), so check before you start to see if you’re using SMS to confirm logins.
