I have been using taxis a lot -- even as primary city transport service. Early 2000: pretty much I used to go to work and back by taxi.
I could call, they'd know the calling phone location (land lines, so that was fixed). Alternatively I'd have to tell where I was and where I'd like to go to. Either they would tell how much time it'd take, plus the car number picking me... or call back with the same info, if no immediate taxi was available.
The meters were a must - both distance and time and you got a receipt at the end. That's like 17-18y ago.
