Cell Broadcast went live on February 23, 2023. The Cell Broadcast service works without the need to install a warning app and complements the existing warning apps such as NINA or Katwarn. In contrast to an SMS, a warning sent via Cell Broadcast reaches every device in a mobile communications cell that is ready to receive such messages.
When you receive a warning message via Cell Broadcast, the mobile device usually makes a loud warning sound. At the same time, the device also displays a text message that is also even read out on some devices, e.g., fire, an accident or a natural disaster. The text message contains instructions on what to do as well as informative tips.
Important: The respective authority/ministry is responsible for the warning content. No all-clear is usually sent via Cell Broadcast. The relevant authority or ministry is responsible for the content of the warning. No all-clear notification is usually issued via Cell Broadcast.
