Owners of smartphones based on the operating system Android periodically encounter intrusive notifications from emergency services. These messages, delivered through the Cell Broadcast system, can interrupt important calls, games, or applications at the most inopportune moment. Users are often looking for a way to block messages from the Ministry of Emergency Situations on Android in order to maintain silence or avoid panic caused by technical tests of the system.

However, completely blocking such notifications is not always possible and, in some cases, is not recommended from the point of view of personal safety. Cellular communication standards provide a priority channel for transmitting information about natural disasters, man-made disasters and other threats to life. However, the settings of most modern devices, such as Samsung Galaxy, Xiaomi or Pixel, provide tools for managing the category of alerts received.

The nature of Cell Broadcast messages and their differences from SMS

To understand the shutdown mechanism, you need to understand the data transmission technology. Messages from rescue services use the Cell Broadcast (CB) protocol, which is fundamentally different from the usual SMS. Unlike text messages, which are sent to a specific phone number, Cell Broadcast is broadcast to all devices within the coverage area of ​​a specific base station.

This technology allows you to deliver an alarm instantly to thousands of subscribers, without creating the network load that occurs when sending mass individual messages. The protocol works at the level of the smartphone's radio module and operating system, often bypassing standard spam filters or Do Not Disturb mode. This is why conventional methods of blocking numbers do not work here.

Each such message has a unique identifier and severity category. The ETWS (Earthquake and Tsunami Warning System) and CMAS (Commercial Mobile Alert System) classify alerts by threat level. Some of them, such as information about an imminent disaster, can be programmed at the phone firmware level as non-deletable and non-disabled to ensure that the information reaches the user.

⚠️ Warning: Completely disabling all alert channels may deprive you of critical information in the event of a real emergency. It is recommended to disable only test messages or notifications of low severity.

Standard alert settings in Android

Most smartphone manufacturers provide users with access to manage emergency alert channels through the system menu. The path to these settings may differ slightly depending on the version Android and shell of the manufacturer, but the logic remains the same. Typically, these options are hidden in the application settings or accessibility section.

To access the configuration, you need to go to the menu Settings → Applications → Special access → Wireless emergency alerts. In some cases, this item is included directly in the section Security and emergencies. Here the user sees a list of categories of messages that the device is ready to receive and display on the screen.

The control interface is usually a set of switches (toggles) opposite different types of threats. You may come across categories such as “Extreme Threats,” “Severe Threats,” or “Test Messages.” Disabling the switch opposite the category Test or AMBER Alert will allow you to stop receiving unnecessary notifications without blocking signals about real danger.

It is worth noting that on devices with a “clean” Android (for example, Motorola or Google Pixel) the menu may look more ascetic, whereas in shells One UI from Samsung or MIUI from Xiaomi there is a more detailed gradation of notification types. If you don't find the item you want in the standard menu, it may be that your carrier or region does not support detailed filtering at the software level.

💡

If the switches in the menu are active (grayed) and not clickable, this means that the restriction is set at the level of the carrier or regional security settings. In this case, software disabling is impossible without obtaining root access.

Specific settings on Samsung, Xiaomi and Huawei smartphones

Large electronics manufacturers often modify the standard behavior of the alert system, adding their own interfaces or, conversely, limiting user access to them. Let's consider the features of popular brands, since their paths to settings can differ radically.

On smartphones Samsung settings are often placed in a separate “Messages” application or hidden deep in the system security settings. Owners of devices of this brand should pay attention to the “Wireless emergency notification settings” item, where you can configure in detail the types of received signals. On some Samsung models, the function of blocking test messages may be hidden under the additional “Advanced” menu.

Devices from Xiaomi i Huawei have their own characteristics due to aggressive optimization of the battery and work with notifications. Here, EMERCOM alerts can be blocked by the system as “intrusive notifications” if you do not add the service to the white list. However, to legally disable it, it is better to use the built-in notification manager, which can be found by searching in the settings for “Cell Broadcast” or “Distribution List”.

Smartphone brand Path to settings (approximate) Blocking features
Samsung Settings → Biometrics and security → Emergency alerts Detailed filtering by threat types
Xiaomi / Redmi Settings → Passwords and security → Confidentiality → Special access Blocking via management is possible notifications
Huawei / Honor Settings → Security → Emergency alerts Operator confirmation is often required
Google Pixel Settings → Applications → Special. access → Wireless emergency notifications Minimalistic interface, minimum options

It is important to understand that the menu interface may change after a firmware update. Manufacturers regularly revise the location of points to accommodate new safety standards or changes in shell design. If you cannot find the section you need, use the built-in search for the phone settings.

Why might the settings be missing?

On some devices intended for certain markets, the Cell Broadcast control menu may be completely hidden by the manufacturer at the request of local communications regulators. In such cases, it is impossible to disable messages using standard methods.

Using the engineering menu and hidden codes

For advanced users who did not find the necessary options in the standard interface, there is access to hidden diagnostic menus. These tools are intended for engineers and testers, but allow you to manage radio parameters, including Cell Broadcast settings. They are accessed through a set of special commands in the Phone application.

One ​​of the common methods is to enter a code ##4636##. This code opens the testing menu, where you can find the Information about the phonesection. Inside this section there is sometimes a “Broadcast Settings” or “Cell Broadcast Settings” item. Here you can try to uncheck the boxes for receiving messages.

Another option is to use a code *#0011# (relevant mainly for devices on Samsung Exynos processors), which opens the network status service menu. However, be extremely careful: changing parameters in the engineering menu can lead to unstable network operation, signal loss, or resetting the modem. Inexperienced users should refrain from experimenting in this section.

⚠️ Attention: Entering commands into the engineering menu is at your own peril and risk. Accidentally changing network settings can cause the phone to stop seeing the SIM card or connecting to the Internet. Before making changes, write down the original parameter values.

You should also take into account that on modern versions Android (starting from 10 and higher), access to many engineering functions has been limited by Google developers for security reasons. Therefore, on new smartphones, these codes may simply not work or open a stripped-down menu without the ability to edit Cell Broadcast parameters.

Restrictions from the telecom operator and legislation

Even if your smartphone has all the necessary switches, the final decision on message delivery is often made by the cellular operator. Operators are required to broadcast signals from the state warning system in accordance with the legislation of the country. This means that some categories of messages marked as “Presidential Level” or “Imminent Threat” will be force-delivered.

In the Russian Federation, for example, the operation of the alert system is regulated by federal laws, which oblige operators to ensure that signals reach subscribers. Technically, this is implemented through a priority channel, which the phone does not have the right to ignore at the software level without breaking communication protocols. Attempts to circumvent this restriction may be considered network interference.

In addition, telecom operators can update settings profiles on your SIM card remotely. If you successfully turned off notifications in your phone menu, but after a while they appear again, your operator may have reset your settings or changed the broadcast settings in your region. In such a situation, repeated disabling through the menu may not have a long-term effect.

Users should distinguish between commercial mailings from operators (advertising, news) and government alerts. The former can be easily blocked through the support service or the USSD command, while the latter are part of the civil defense infrastructure and their blocking is extremely difficult on purpose.

💡

The legislation of most countries prioritizes the citizen's right to receive information about a threat to life over the right to silence, so complete blocking of signals of the highest danger category is technically impossible using legal methods.

Alternative control methods notifications

If standard methods do not help, and annoying messages continue to arrive, you can try using third-party notification management tools. There are filter applications that are capable of intercepting system notifications and hiding them from the user, although the signal itself at the modem level will still be received.

One ​​of the softer ways is to use the Do Not Disturb mode with fine-tuning exceptions. You can set your phone to turn off sound and vibration for all notifications except calls from your favorite contacts at certain times (such as at night). However, Cell Broadcast messages often have high priority and can even break through this mode, producing a specific loud siren sound.

It is also worth considering installing custom firmware (Custom ROM) if you are an experienced user. In some unofficial builds Android enthusiasts remove the functionality of mandatory notifications or provide full control over them. But this method is associated with a loss of warranty and a risk of data security, so it is suitable only for a narrow circle of technical specialists.

  • 📱 Set the Do Not Disturb mode to minimize the sound.
  • 🛡️ Use notification filter applications to hide the text of the message.
  • 🔧 Consider installing custom software only if you have the appropriate skills.
  • 📞 Contact your telecom operator to clarify the possibility of disabling test channels.

Before installing any filters, make sure that they are compatible with your version Android and do not contain malicious code.

Frequently asked questions (FAQ)

Is it possible to completely disable messages from the Ministry of Emergency Situations forever?

It is impossible to completely disable all types of messages, especially the highest danger categories, at the legal level. The telephone is required to receive signals that threaten the lives of the population. However, you can disable test messages and warnings about less serious events through the system settings.

Why do messages appear even in Airplane mode?

This is a myth. In Airplane mode, the radio is turned off completely and the phone loses contact with cell towers. Therefore, it is technically impossible to receive a Cell Broadcast message in this mode. If the message appears after the mode is turned off, it means that it was accumulated by the network and delivered immediately after the connection was restored.

Will the phone work if I turn off all notifications?

Yes, the phone will work normally. Disabling alerts only affects the reception of broadcast messages from emergency services. Calls, regular SMS, mobile data and application operation will not be affected.

How to distinguish a test message from a real alarm?

Test messages usually contain the word “TEST” or “TEST” in the title or text. Real alerts contain specific information about the threat, instructions for action, and an indication of the region of danger. In the phone settings, you can often disable the “Test messages” category, leaving real threats active.

Does blocking messages affect Internet speed?

No, Cell Broadcast messages are received over a separate logical channel and do not affect the throughput of the data channel (4G/5G). Blocking these messages will not speed up or slow down your Internet.
