What are these "Channel messages"? (In German, "Kanalnachrichten")
Occassionally I'm receiving a notifitcation titled as "Kanalnachricht". There are to numbers displayed. To give you a picture I uploaded a picture in my blog:
I have not yet scanned the source code to determine, why I receive those notifitcations. I assume, it could be due to "Receive cell information" setting in the "phone settings" dialog (c.f. preferences app).
Soon I'll crosspost this issue in the German carrier's forum (i.e. in the Congstar forum) in German.

Some providers (e.g. O2 in Germany) send Cell Broadcasts on Channel 221. They use it to post the coordinates of the base station so it can be determined for example, if the phone is in the home zone. So it seems to me that this could well be caused by the "receive cell information" setting. I'm not sure about other providers - so if you use Congstar/T-Mobile, I'm not sure, if the above is valid.

Oh, look, there were an answer O:

However, Congstar confirmed your assumption partially.
There's no "home zone" offered by them, but by other carriers using D1.
