Public phone booths

The photo shows public phone booths in Athens, Greece. I took this photo near the National Gardens on my way back from 1896 Olympic Stadium. Public phone booths have been disappearing in many cities because of the ubiquitous use of cell-phones, so four public phone booths in a row was kinda interesting to me and took a photo of them. I was a cell-phone holdout actually, but a year ago finally I bought one out of necessity. I don't know from when, but I don't often see public phones like I used to. What's the matter with them?
