Cell broadcast warning day in Germany: Thursday, December 8, 2022

Do you still remember the big announced warning day in September 2020? That was quite a letdown. Cell broadcast technology was discussed last year as a solution to the chaos of sirens, app warnings and the like (we reported). Now all hurdles to use seem to have been cleared, and the time has come: Tomorrow is the first "Cell Broadcast" warning day in Germany. Without an additional app, the test warning should be sent to the corresponding end devices very easily via mobile communications, i.e. via SMS. The whole thing is called DE-Alert in this country and should take place at 11:00 a.m. The all-clear should be given at 11:45 a.m.

Thursday, December 8th, 2022 is DE-Alert warning day. Warning and all-clear are sent via cell broadcast. You can find details on this in this post.
Thursday, December 8th, 2022 is DE-Alert warning day. Warning and all-clear are sent via cell broadcast. You can find details on this in this post.

Level 1 alerts should be implemented with text and sound

In addition to a text message indicating the Alert Level 1 alert at 11:00 a.m., compatible devices will also play an alert tone. This may be a rapid alternation of two loud tones. 

On the one hand, this is intended to emphasize the warning character of the tones and, on the other hand, to enable a clear differentiation from the other signals and ringtones of the device. The warning tone for cell broadcast and thus for the DE alert is not the same on all devices, so it can vary depending on the manufacturer and model. 

Information for Apple users: DE alert on Cell Broadcast on the iPhone

On the Apple iPhone, receiving the warning and the all-clear is at least iOS 16.1 provided. If you have a device with iOS 15, you should update it to at least iOS 15.6.1. It is best to have the latest iOS version installed; so currently iOS 16.1.2. You can find out which ones you use under Settings -> General -> software update. Devices with earlier systems (iOS 12, iOS 13, iOS 14) will not receive the warning as of now.

The reception of cell broadcast and thus the reception of the DE-Alert should be activated by default in the compatible operating systems - however, the reception of test warnings may be deactivated. If you want to check this and adjust individual settings, you can also do this in the settings of the Apple smartphone. Here are the step-by-step instructions for doing so:

  1. Opens the Settings on your Apple iPhone
  2. Choose the point in it Messages from
  3. Scroll all the way down to the Cell Broadcast Alerts section
  4. Activates the last slider test warningsif you want to be on the safe side
  5. It is best to leave the other two controls for Extreme Danger and Hazard Information activated

  1. Hi John,

    On my IPhone 14 Pro only Katwarn mattered. Cell broadcast alerts were also not found in the notifications. I have now manually updated to ios 16.1.2. Now the cell broadcast alerts are displayed. "External danger" and "Danger information" were switched on "Test warnings" were switched on myself. Although I had automatic updates turned on, ios was not up to date! I do not know why.

    Wish you and the entire team including families MERRY CHRISTMAS 🎄🎄🎄 and a HEALTHY 2022
