How to remove SMS on Xiaomi: a complete guide to cleaning messages

Managing incoming correspondence on Xiaomi, Redmi and Poco smartphones requires periodic attention, as the accumulation of old dialogues can slow down the message system. Users often face the need to quickly clear the history of correspondence from spam or simply free up space in the memory of the device. The deletion process can vary depending on the version of the MIUI shell or HyperOS, as well as the type of application used for SMS.

In this article, we will take a look at all the existing methods of removing text messages, from erasing one particular note to completely cleaning the database, learn how to work with the standard Messages app and alternative clients, and understand whether it is possible to return deleted content back.

Delete individual messages and entire dialogues

The most common scenario is to remove one particular message from the chain or delete the entire contact dialog, which is done by long pressing in the standard MIUI shell, and when you press your finger on the text, you have an action menu where you can select the deletion option.

If your goal is to erase all the correspondence with a certain number, the algorithm changes a little, so you need to go to the general list of all the dialogues, find the right subscriber and do a long press on his name or preview of the last message, the system will highlight a line, and at the top of the screen will appear a toolbar.

• 🗑️ To delete one entry, select it with a long tap and click the basket icon in the menu that appears.
• 📁 To erase the entire branch, pinch the dialog in the shared list and confirm the action in the pop-up window.
• 📤 The function “Delete for all” in conventional SMS does not work, as it is a cellular protocol, not a messenger.

⚠️ Note: Once the dialog has been confirmed, it will not be possible to restore it with standard system tools, so check the selected contact before the final action.

It is important to note that deleting a message from the outgoing does not mean that it did not reach the destination: SMS is a one-way protocol, and after sending a copy remains with the operator and the recipient. Local deletion affects only the memory of your Xiaomi smartphone.

Massive cleanup of message history

When memory is full or you want to start with a clean slate, it’s more convenient to use the mass cleaning feature. Xiaomi’s Messages app offers a convenient mechanism for allocating multiple dialogs at once, which allows you to get rid of dozens of branches at a time, which is especially important after changing your SIM card or number.

To activate the selection mode, it is usually enough to press and hold your finger on one of the dialogs in the list, after which checkboxes will appear opposite each name. You can scroll through the entire list and mark the conversation that is to be destroyed. Alternatively, using the menu "More" or three dots in the corner of the screen.

There is also an automated way to clean through storage settings, and the system can suggest that you delete all messages over a certain period, such as those over 30 days, and it's useful for maintaining the hygiene of the digital space without the risk of removing important codes right now.

• 📂 Go to the storage management menu inside the message application.
• 📅 Select a filter by date or size of the attachment (MMS).
• ✅ Confirmed removal of selected message groups.

⚠️ Note: During a mass cleanup, be careful not to highlight dialogs with banks or two-factor authentication services where access codes may be stored.

Dealing with blocked messages and spam

The MIUI and HyperOS shells have a powerful antivirus and spam filter built in, and all messages from unknown numbers or containing stop words automatically go to a separate Spam or Blocked folder, which are not displayed in the shared list or alarm the user with audible signals, but take up space.

To remove such spam, you need to log into the filtering settings. Usually the path looks like Settings → Messages → Antispam or through the Security app. Inside you will see a list of all blocked communication attempts, they can be deleted one by one or clear the entire lock log at once.

Interestingly, deleting a blocked list does not automatically blacklist a number if it wasn't already there, it's just cleaning up the event log, and if you want to completely stop receiving SMS from a particular sender, you have to blacklist it manually.

Cleaning Multimedia Investments (MMS)

Text messages take up negligible space, but multimedia attachments (pictures, audio, business cards) can quickly eat up gigabytes of memory. Unlike regular texts, MMS are stored in gallery and system folders. Simply removing text messages is not enough to make room if there were photos in the dialogue.

To clean up effectively, you need to use a built-in storage analyzer. The Security app on Xiaomi has a Cleanup section that finds large files, including attachments from messages. Deleting through this tool ensures that you erase both the file itself and the link to it in correspondence.

It's also worth checking the Internal Storage/MIUI/mms folder through the file manager, sometimes with tails from deleted dialogs -- files that the system didn't delete automatically -- and manually checking that directory helps free up a few more megabytes.

Using Google Messages on Xiaomi

Many Xiaomi users prefer to replace the standard app with Google Messages. The interface and deletion logic are different there. There is no built-in shopping cart in the Google app, so deletion is instant and irrevocable if synchronization is not enabled.

The deletion process in Google Messages is similar to the system: a long press highlights the dialogue, and swiping left or right on a message in an open correspondence allows you to delete a specific replica. However, mass allocation here is implemented less convenient for inexperienced users.

An important feature is cloud integration. If you use the web version of messages, deleting correspondence on your phone syncs with the browser. This provides a unified history, but requires caution: once you clear the chat on your PC, you lose it on your smartphone.

• 🌐 Removal syncs between device and web version.
• 📵 The “Delete for All” function only works in chat mode (RCS), Not a regular text.
• 🔄 The app cache needs to be cleaned separately through Android settings if display errors occur.

Can I Restore Removed SMS?

Recovery of deleted messages on Xiaomi is a hot topic, because there is no built-in messaging basket in the app. If you accidentally delete important code or correspondence, standard methods will not be able to return them. Android immediately marks the memory space as free to write.

The only reliable way is to have a backup. On Xiaomi, you can set up auto-save SMS to the Mi Cloud or Google Drive. If the backup was created before you delete it, you can restore data by resetting your phone or using the cloud recovery feature when you first set up.

There are third-party recovery programs (like Dr.Fone or DiskDigger), but they are not guaranteed to work, they work by scanning deep memory sectors, but on modern smartphones with encryption, the chances of success are extremely small without superuser rights (Root).

⚠️ Warning: Do not install dubious applications from unverified sources that promise instant SMS recovery. Often these programs are viruses or require payment for a result that cannot be provided.

If backup is not available and the data is critical, the only option is to contact the carrier, but operators only store the metadata (who, to whom, when) and the contents of SMS under the Communications Act for a very short time, providing this information usually only at the request of law enforcement agencies.
