How to view blocked SMS on Xiaomi Redmi: the full guide

Xiaomi and Redmi smartphone owners often face a situation where important messages from banks, delivery services or friends suddenly stop coming or disappear from the incoming list, which can be caused by aggressive MIUI filters that accept legitimate mailings as spam, or by third-party blocking applications. Understanding where the system sends such messages is the first step to solving the problem of data loss.

Modern Android shells, including MIUI, have built-in protection mechanisms that operate autonomously and can hide content without the user’s knowledge. Blocked messages on Xiaomi devices are often not permanently deleted, but moved to a special hidden folder “Antispam” or “Blocked”. In this article, we will discuss in detail the algorithms for finding such messages, methods for restoring them, and how to fine-tune filters to prevent loss of information in the future.

There are several scenarios in which a user loses access to SMS, which can be an accidental lock of a number, a SIM card overflow memory or a conflict of system applications, diagnosing the problem requires a consistent check of all possible storage locations. Don't panic if you don't see the expected confirmation code - it is most likely in the quarantine of the security system.

Check the standard application Messages and Antispam folder

The first and most obvious place to look for missing messages is the standard Messages app, which is preinstalled on all Xiaomi smartphones. The system groups incomings not only by contacts, but also by security status. Often users simply do not notice a separate tab or icon indicating quarantine.

To get to the desired section, you need to open the application and carefully examine the interface. Depending on the version of MIUI, this can be the tab “Antispam”, “Blocked” or a separate folder in the menu of chat settings, the system automatically sorts messages containing links or sent from short numbers, placing them in an isolated area.

• 📱 Open the Messages app on the main screen.
• 🛡️ Click on the shield icon or three-dot menu in the corner of the screen.
• 📂 Select “Antispam” or “Blocked Messages».
• 🔍 Check out the Spam and Blacklist lists».

Within the anti-spam folder, messages are often divided into categories. You can see separate listings for blacklisted numbers and for messages marked as spam by Google or Xiaomi algorithms. Recovering a message from this section is usually done by simply dragging and dropping or selecting the "This is not spam" option, after which the message is returned to the general inbound list.

💡

If you find the desired message in the Antispam folder, be sure to add the sender number to the contacts or whitelist so that in the future messages will come directly.

Using the Security Application to Search for SMS

Redmi’s central restriction management node is the system application Security, where the resides engine filters calls and messages, and when a standard messaging app doesn’t display the data, a deep search through the security menu often yields a more complete result.

Security aggregates data about all blocked events, which stores not only the history of current blockings, but also archival data that may have been removed from the main interface, access to this data is protected, but not completely hidden, which allows the user to control the operation of filters.

To access the extended event log, follow the following steps:

1. Launch the Security app (green icon with shield).
2. At the top of the screen, find and click on the Antispam icon (usually looks like a shield with a forbidding sign).
3. In the menu that opens, select the Record tab or the Watch/History icon in the upper right corner.
4. Switch the filter to display only SMS if the calls are by default.

In this section, you'll see a detailed log of all the messages that were intercepted by the system, which shows the time, the sender number, and often the preview of the content. MIUI allows you to export that data or move it right away to the inbox, and it's the most reliable way to find messages that are cut off at the system level.

Setting up black and white contact lists

A common reason for blocking SMS is the erroneous blacklisting of a number, which can occur by accident when dialing a number or as a result of a contact synchronization failure, and the blacklist completely ignores any attempts to communicate with the specified numbers, without notifying the user of incoming events.

Lock lists are managed through the same Antispam menu in the security app, and you can see the full list of numbers that are not allowed to access your device, and it is important to review this list regularly, as short service numbers of banks or taxi services can get into this list.

To adjust the filters correctly, do the following:

• 🚫 In the Antispam menu, click on the gear (Settings).
• ✅ Select the item "Black List».
• ➕ Check if the numbers are available and delete them if necessary.
• ⚪ Go to the White List and add important service numbers.

⚠️ Warning: Numbers added to the whitelist ignore all spam filtering rules.Use this feature with caution, adding only verified senders to avoid opening the floodgates to real junk.

You should also pay attention to the settings of “Smart response” and filters by keywords. Xiaomi allows you to block messages containing certain phrases (for example, “credit”, “promotion”). If you have set up such filters before, check their contents – it is possible that an important message was screened out by the coincidence of the keyword.

Recovery of messages from SIM-map

In the age of smartphones, we often forget that SIM-If the messages are not saved to the phone book or the message application has been reset, the confirmation codes and important notifications may remain on the SIM card chip.

To view the contents of a sim card on Xiaomi, you need to use a specific path in the settings, since the standard application can default to ignore this medium, usually there are old messages or messages that came when the phone’s memory was full.

Algorithm of actions for verification SIM-memory:

Settings -> Applications -> Messages -> Storage -> Message management on SIM- card

Or an alternative way through system settings:

Settings -> Password and security -> Privacy -> Special features -> Messages on SIM- card

(The path may vary slightly depending on the Android and MIUI versions.)

In this section, you'll see a list of messages that are stored directly on the chip. There's a limited functionality here: usually only read and delete is available. However, if you find a lost SMS there, it can be rewritten manually. SIM-Phone memory cards on modern versions of Android are often not available directly through the standard interface.

Problems with messages from banks and service providers

A separate category of problems is related to messages from financial institutions and large services, banks use special communication channels that Xiaomi security systems can mistakenly classify as spam due to high frequency of mailings or similarity to phishing attacks.

If you don’t get a text message from the bank, but you’re sure the number isn’t blacklisted, the problem may be in the notification settings for a particular aggregator application or the operator’s work, sometimes “lost” messages on the operator’s side due to overflowing of the delivery channel.

Table of possible reasons for blocking service SMS:

To solve the problem with banks, it is often necessary not only to unlock the number, but also to reset the filter settings for short numbers. The Security app has the option “Block by Keywords” – make sure that there are no words used by the bank in the mailings (for example, “code”, “payment”, “card”).

Third-party applications and deep recovery

If MIUI's built-in tools have failed to find lost data, third-party solutions come to the rescue, and data recovery applications and alternative SMS clients can access system databases that are hidden from the standard interface.

A popular solution is to install applications like SMS Backup & Restore or GT SMS Recovery, which can scan hidden sections of the mmssms.db database, where the history of all correspondence is stored, including deleted (but not overwritten) records.

• 📥 Download the proven recovery app from Google Play.
• 🔐 Provide the necessary permissions to access SMS and storage.
• 🔍 Start a deep scan of the device.
• 💾 Save the messages found to the cloud or file XML.

⚠️ Note: When installing third-party SMS applications, you give them access to your personal correspondence. Use only high-rated and positive-review programs, avoiding dubious software that may pass your confirmation codes to third parties.

Also worth mentioning is the ability to view messages via Google Messages in the web interface, if the phone was enabled cloud backup or sync with a Google account, a copy of the message could be saved in the cloud even if it was deleted or blocked on the device.

💡

Android system logs and databases store traces of messages longer than the user interface. Deep search requires superuser rights (Root) or specialized software.
