Since I have a Fairphone 4 now, I did receive a broadcast test message today at 11 am.
Have you checked your emergency alert settings?
Yes, all settings switches are and were activated.
I checked it the day before.
They are activated by default. So I did not change anything.
I also asked people around me with the same carrier.
Schau mal ob die App “Cell Broadcast Service” bei dir in den Berechtigungen den Standort mit drin hat oder nur SMS.
Einstellungen/Apps/AlleApps/ System Apps einblenden/ dann die app suchen
Didn’t receive any yesterday 
.
All checkboxes were checked as shown on the screenshot. Cell Broadcast has location permissions.
War einwandfrei mit Ton und Text bei meinem XA2
worked fine on a Sony XZ2 and a Samsung S10e, both with iode 4.4
I have a FP4 and my carrier is Vodafone. I got the alert this and last year and the bavarian one in the beginning of 2023 in english and german.
on Thu 2025-09-11 there was another “Warn Day”, Samsung A528B (A52s 5G) with active Dual-SIM (Telekom and Vodafone) and iodeOS 6.7 did not react, but checked the Emergency settings in advance and explictly enabled “Test warnings” 
On my Sony XZ2 iode 6.7 carrier O2, the alarm arrived
With pixel6a and 7a it had worked. With S10e with iodé 4, I don’t know, I have turned off.
Fairphone 4 5G, iodé 6.6, carrier O2, it worked just fine
OnePlus 11, iodè 6.7, carrier telekom/o2, works
It even worked without a SIM card (just WLAN). Was 8 minutes late, but it did show up. (Motorola G32, iodéOS latest build).

It didn’t work on my S10e with iodé 4.
Well, I hope that’s a typo as the current version I have installed is 6.x
I’d guess that 4.x had no support for cell broadcasting?
Some older devices don’t have A15 / LOS22 / iodé 6.x support, but still have A13 / LOS20 / iodé 4.x builds created.
