Get dozens of promotional messages a day? Are you bullied by scammers with “win” offers? Xiaomi Poco smartphones (including the POCO F5, X5 Pro, M6 Pro and more) offer several built-in tools to combat unwanted SMS — from a simple blacklist to advanced artificial intelligence filters.
5 working methods of blocking SMS, including hidden functions MIUI, We'll look at how to weed out spam from banks, telecoms and marketing mailings, and what to do if standard tools don't work. SIM-The card only works on the firmware. MIUI 14+ and requires activation of the service from the operator.
1. Contact blacklist: basic method of blocking
The most obvious way is to blacklist a number, but MIUI has a deeper hidden feature than any other shell to find it.
- Open the Messages app (an envelope icon).
- Sms an unwanted text and hold your finger for 2 seconds.
- In the menu that appears, select Block (on some models, Add to the blacklist).
- Confirm the action by pressing OK.
The main disadvantage of the method is that the lock only works for a specific number, if the spammer uses different numbers (for example, mass mailings from operators), you have to add each one manually, and blocked SMS can still appear in the Spam folder, if you do not turn off this option in the settings.

- Go to Settings → Applications → Messages → Message settings.
- Select the Spam Filter.
- Activate the switch to Enable the spam filter.
- In the section Filter settings, tick tick: 📌 Filtering advertising messages 🔍 Filtering fraudulent messages 📱 Filter messages from services (to block SMS from banks and operators)
