I get the impression that almost all countries use Touch Tone service on their telephones. For places that never had much landline service to begin with, people are heavy into cellular, which of course is Touch Tone. (Apparently in an undeveloped place it's cheap to build a new cellular network than landline since stringing wires house-to-house and store-to-store are not required.)
Anyway, I was wondering if there were any places where legacy rotary dial switchgear was still the primary method of handling calls. I tend to doubt it since electronics are so much cheaper and easier to maintain. Rotary equipment required skilled maintenance.
Public replies, please.
