I don't remember seeing any at all on recent trips 8-(

Where did you look?
For instance, in Germany, almost every village and town has one or more
pink 'Deutsche Telekom" booths. These are usually just half booths, a
metal pole with a sign and a pink/silver phone. This is what they look

Any geocacher will be able to point you to these, because many of them
are hiding places.
In Belgium, you can't miss these:

Side note: in Bad Zwischenahn, a closed, yellow phone booth is now in
use as a free public library. An amazing sight!
