Decicing via radio call

[bpcw0001]

Hi,

I tried to use the 136.925 frequency from the cockpit to call for decing, in order to test this and prepare for the upcoming colder season.
The menu comes up, I can select decice or deice/anti-ice, but then nothing happens.

There is no truck coming, or anything else happening that might indicate a decicing/anti-icing process. Tried on several different airports, but no luck so far.
Sure, currently we don't need decing/anti-icing since it is summer and temps are high. Is this checked somehow, and this will only work in true icing conditions?

What's the deal here? What are the prerequisites for this to work? 
I am parked normally at the airport, with all engines running and ready to go.

Ah, ok, it worked at BGBW (Nasarsuaq airport in Greenland).

It also works when I manually create icing weather conditions at an airport.

So it does check for actual icing conditions? And if there are none, the deicing guys will just do nothing?
Nice that they don't tell me in that case
