Feedback on the civil defense test alarm

So far, a lot of feedback has been received from the population about the civil defense test alarm. The messages about AT-ALERT are of course very helpful for checking the system in Vienna because they are being used for the first time. Despite the technical failure of the contact page for the sirens, a lot of feedback was received via the siren phone. Feedback on the perception of the signals is possible until October 11, 2024.

The initial feedback also raised the question of how to unsubscribe from this system. It must be said that no telephone numbers are known, but only sent to mobile phones that are ready to receive. The transmission took place via the radio cells of the mobile phone operators. The final reception also depends on the age and the corresponding operating system. This could result in alarms not being received on the cell phone. (End) red
