Have you ever seen a sudden notification on your Xiaomi screen with a loud signal that you canβt ignore? These are emergency alerts β a special mechanism designed to alert users to potential threats, natural disasters or other critical situations. Unlike conventional push notifications, such messages have the highest priority: they break current tasks, activate vibration and sound at full volume, and sometimes even block other functions of the phone before reading.
Emergency alert system built into firmware MIUI and operates on the basis of state and regional alert services (for example, CMAS However, many users do not know how these notifications are turned on, whether they can be disabled and why they sometimes come with a delay. In this article, we will discuss in detail all aspects of the work of emergency alerts on Xiaomi β from technical nuances to practical tips for setting up.
What are emergency alerts and why do they need them?
Emergency Alerts is a mass-media system designed to provide critical information quickly in cases where:
- πͺοΈ Natural disasters: hurricanes, floods, earthquakes, forest fires.
- β οΈ Technogenic disasters: accidents at nuclear power plants, chemical leaks, explosions at enterprises.
- π¨ Terrorist threats: evacuation, blocking of areas, search for dangerous criminals.
- π₯ Medical emergencies: pandemics, quarantines, mass poisoning.
Unlike in the past. SMS Emergency alerts use a cell network (Cell Broadcast technology), which allows you to send messages to all devices in the coverage area β even if the phone is not connected to the Internet or the user does not have a mobile phone. SIM-At Xiaomi, these notifications are processed at the firmware level. MIUI, They cannot be blocked through standard notification settings.
It is important to understand that emergency alerts are not carrier-dependent, they are broadcast directly from government services through cell towers, which means that you will receive an alert even if your phone is in βairplaneβ mode (provided that Cell Broadcast is enabled).
β οΈ Note: In some countries (e.g. the U.S. and Canada), it may be illegal to turn off emergency alerts.
How to use Xiaomi emergency alerts: technical details
Xiaomiβs emergency alert mechanism is based on three key components:
- Hardware support: All modern Xiaomi smartphones (starting with the Redmi Note 5 and Mi 8) are equipped with a chip that supports Cell Broadcast technology.
- Firmware MIUI: Notification processing is carried out by the system application com.android.cellbroadcastreceiver.
- Public services: the source of alerts are local departments (EMERCOM, FSB, weather services, etc.).
When the service sends an alert, it is broadcast to all cell towers in a given region. The phone in the coverage area receives the signal and displays the notification according to the settings. MIUI. And yet:
- πΆ The message is received even with a weak signal (sufficient). 1-2 "stick").
- π The sound is played at maximum volume, ignoring the profile settings.
- π The notification is repeated every 2 minutes until the user reads it.
On Xiaomi, emergency alerts are divided into three categories according to their level of importance:
| Type of alert | Examples | Can I turn it off? |

| Presidential (Extreme) | Nuclear threat, martial law | β No. |
| Critical (Severe) | Earthquake, tsunami, hurricane | β οΈ Partially (depending on country) |
| AMBER Alerts | Search for missing children | β Yes (most countries) |
| Testing. | Checking the warning system | β Yes. |
Xiaomi does not technically control the content of the alerts, but only displays what the government service broadcasts. MIUI There are tools for filtering spam and duplicates, which we will talk about later.

- π Firmware Region: Global Versions MIUI Allows you to turn off more types of alerts.
- π‘ Operator policies: some providers block these settings from changing.
On most Xiaomi devices, you can turn off:

- β AMBER Alerts (search for children)
- β Meteorological warnings (in some countries)
But critical alerts (for natural disasters or terrorist threats) cannot be turned off, as is a requirement of many countries, and if you see a gray (inactive) switch in the settings, then this type of alert is blocked at the firmware level.

|---|---|---|
| The warnings don't come at all. | Cell Broadcast disabled in settings | Include in Settings β Annexes β Emergency alerts |
| Delay. 10-30 minute | Weak network signal or tower overload | Move to the area with the best coverage |
| Duplicates are coming. | Failure of the alert service | Clear the app's cache Emergency Alerts |
| Foreign language alerts | The inconsistency of the firmware region and SIM-map | Install global firmware or change SIM |
A common cause of problems is a mismatch in the firmware region, for example, if you use Xiaomi with Chinese firmware (China). ROM) in Russia, then:
- You will receive alerts from Chinese authorities (e.g., typhoons in Guangdong).
- Local alerts (from the Ministry of Emergency Situations of Russia) will not come.
- The text of the notifications will be in Chinese, even if the system is translated.
Solution: Flip-on MIUI Global or MIUI EU. Also check that the phone settings indicate the correct region:
Settings β Additional β RegionIf the alerts are delayed, it may be due to network congestion, and during a mass emergency (such as an earthquake), cell towers process thousands of requests simultaneously, leading to delays.
- π» Turn on the radio (if any) FM-receiver) to obtain alternative information.
- π± Use messengers (Telegram, WhatsApp) to communicate with loved ones.
- π Save battery power by disabling background applications.

How to distinguish a real emergency alert from a fraud
Unfortunately, scammers sometimes disguise their messages as emergency alerts to trick users into going to phishing sites or downloading malware.

- β Fake Alert: Comes as usual SMS It contains links to unknown sites, requires personal information or money transfer, has typos or strange language (for example, "Your account is blocked!").
If you doubt the authenticity of the alert, check it through official sources:
- π° Local Emergencies Ministry or Government Website.
- π» Radio or television (news channels).
- π± Official accounts of social media services.

If you receive a suspicious βemergencyβ notification:
- Do not click on links and do not download attachments.
- Take a screenshot and send it to Xiaomiβs support team or your carrier.
- Check if there are any suspicious apps installed on your phone (Settings) β Annexes).
