This Monday, at 10: 00 pmCivil Protection will activate a mobile phone notification system test in the Barcelona area. The activation is part of the deployment of EN-Alert, a tool designed to quickly and simultaneously alert those in the affected area of emergencies.
For a few minutes, all smartphones Those connected to the area's antennas will receive a drill message in three languages. The measure aims to familiarize the public with the alert system, verify system coverage, and identify potential technical improvements without causing unnecessary alarm.
When and where will the drill take place?
The test will take place in the Barcelona vegueriawhich includes Barcelonès, Baix Llobregat, Maresme, Vallès Occidental and Vallès Oriental. If you are in these regions at the indicated time—whether you live there or are just passing through—your mobile phone will receive the alert as long as it is turned on and with coverage and have them activated civil protection alerts.
The text of the drill notice will appear in Catalan, Spanish and EnglishYou will see an identifying message such as: "PROVA D'ALERTA DE PROTECCIÓ CIVIL DE LA GENERALITAT DE CATALUNYA. En una emergencia real recibirías instrucciones para protegerte".
What it will sound like and what to do when it arrives
The warning will be accompanied by a powerful sound, different from the usualwhich only stops when you interact with the notification on the screen. Even if the phone is on silent or vibrate, the alert will be heard to ensure its effectiveness; please, Don't call 112, since it is a test.
Anyone who needs to avoid the alert for work-related reasons or hearing sensitivity can Turn off the device or activate airplane modeHowever, some models may still display the warning. The test broadcast window will remain active around 10 minutes.
To clarify, here are some key points how the shipment works:
- Requirement: The mobile phone must be switched on and have coverage from its operator.
- Antenna broadcasting: The notification is issued indiscriminately to all terminals connected to the cells activated in the area.
- Approximate area: The territorial delimitation depends on the coverage of each antenna, so there may be overlaps or inexact borders.
- Network priority: The system prioritizes the delivery of the alert over other ordinary communications.
- Without a census of recipients: ES-Alert does not count how many phones receive the message; that is why citizen collaboration will be requested.
- audible alert: Even in silence, the alert is heard until you interact with the notification.
What is ES-Alert used for and real-world use cases
ES-Alert is the state-run mass broadcasting system. Cell Broadcast which issues immediate instructions in the event of serious risks, such as chemical accidents, floods or forest firesIts objective is to transmit clear instructions (for example, confinement or avoid travel) in a matter of seconds.
The usefulness of the system has been called into question after episodes of severe weather phenomena and recent emergencies. In the public debate, some voices have pointed to delays or inconsistent coverage of previous events, which has prompted the implementation of periodic tests to reinforce reliability and range.
In the regions of Barcelona, along 2025 Eight alerts have been sent to mobile phones via ES-Alert: four drills, two for the plan INFOCAT in response to a fire in Terrassa and two others due to the plan INNUCATED due to episodes of heavy rainfall.
Evaluation and citizen participation
Following the drill, the Generalitat will set up a anonymous survey To gather incident details: if you received the notification, in what language it appeared and from which telephone company. This information is used to adjust coverage and the accuracy of future activations.
It is worth remembering that the system itself no record The number of terminals that have received the message. Therefore, citizen collaboration is key and will be carried out without personal data, for strictly technical purposes and to improve the service.
Practical recommendations
When the alert arrives, try keep calmRead the entire message and tap the option on the screen to stop the sound. Avoid calling 112 during the drill; in crowded spaces (offices, classrooms, shops) it's normal for all mobile phones to ring at once, so warn those around you that it is a test.
- If you don't want your phone to ring, turn it off or activate airplane mode before 10:00 a.m.
- If you are in transit through the area (for example, by train or car), you could also receive the alert.
- In a real emergency, always follow the official instructions of the message.
With this activation, Civil Protection seeks improve protocolsto measure the effectiveness of the delivery system in Barcelona and its surrounding area and to strengthen a mechanism that, in real-world scenarios, allows for the issuance of quick and understandable instructions to millions of people. Citizen participation through the survey and adherence to the instructions during the trial will help to perfect a key system for collective security.
